I have spent the last six weeks working through a commercial HVAC retrofit project that required cutting over 400 lengths of strut channel. Before this job, my go-to was a portable bandsaw with a cutoff guide and, when I was feeling reckless, an angle grinder with a thin cut-off wheel. Both methods work. Neither method produces consistent, deburr-free cuts without significant after-work. The bandsaw leaves a burr that needs filing if you value your hands pulling wire through the channel. The grinder throws sparks, eats wheels, and, on a bad day, can distort the thinner strut profiles. I needed something faster, safer, and more repeatable. That led me to the Milwaukee M18 FORCE LOGIC strut shear review,Milwaukee M18 strut shear review and rating,Milwaukee M18 FORCE LOGIC strut shear review pros cons,Milwaukee M18 strut shear review honest opinion,is Milwaukee M18 strut shear worth buying,Milwaukee M18 FORCE LOGIC strut shear review verdict because the promise was specific: shear the strut, not your hands, and get a clean edge every time. I put the tool through three full weeks of daily use, alternating between bench work and cutting strut at installation height off a ladder. This review covers exactly what you get, where it works, and where it will leave you wanting more. If you are weighing this against other methods, I have also compared it against my previous cutting tools and a few alternatives. Read on for the detailed durayu 25×12 livestock shelter review for a different kind of shop addition. For the price and performance breakdown up front, the verdict is below.

Category Context: Where This Product Sits

Strut shears have been around for a while in the industrial trades, but they have almost always been manual, two-handed tools that require significant upper body strength and produce mixed results over the course of a day. The powered handheld strut shear is a relatively new subcategory, and Milwaukee entered it with a clear premium position. At 2,950 USD for the kit, this is not an impulse buy. It sits above the manual shears like the Klenk manually operated cutter and below the larger hydraulic shop shears that cost upwards of 5,000 USD. Milwaukee brings its M18 REDLITHIUM battery platform into the equation, which means this tool shares batteries with drills, impacts, and saws from the same line. The design choice that differentiates this tool from manual shears is the proprietary shearing die system — a dual-die setup that applies hydraulic force to shear the strut between two moving dies rather than using a blade that can dull or create sharp edges. This is a fundamentally cleaner method of cutting than sawing or grinding, but it also creates different constraints around portability and weight that we will cover below. Milwaukee has been making strut tools for about eight years within their FORCE LOGIC hydraulic line, and among experienced electricians on the job site, their reputation is solid but not uncritical — tradespeople appreciate the durability but question the price-to-usefulness ratio for short-run jobs.

What the Box Contains and First Impressions

The kit includes the main shear unit, one set of 1-5/8” x 1-5/8” single channel shearing dies, one M18 XC 5.0 REDLITHIUM battery, an M12/M18 multi-voltage charger, and a soft-sided carrying bag with multiple pockets. The bag can hold up to three additional die sets. Lifting it out of the box, the first thing you notice is the weight — 24 pounds as listed, and it feels every ounce of it. The unit is built around a heavy steel frame wrapped in high-impact polymer housings. The dies are hardened tool steel, and the hydraulic piston assembly is sealed. The finish is typical Milwaukee professional: black and red, with no sharp edges on the housing itself. There is no manual of any significant length included — just a folded quick-start guide that covers battery insertion and die installation. What is absent from the box is a second battery, which feels like an oversight given the price. Cutting strut draws the battery down faster than running a drill, and having only one battery means you are tied to the charger during a long cutting session. You will also need a chain vise or a stable flat surface for optimal use, as the tool does not include a tri-stand.

The Testing Period: A Chronological Account

The First Day

Setting up the shear took about ten minutes out of the box. Installing the dies is straightforward: remove the retaining pin, slide the dies into the slot, and resecure the pin. The ONE-KEY pairing took another two minutes via the app. The first cut I made was a piece of standard 1-5/8” solid strut on a workbench. I placed the strut into the opening, lined up the measurement offset plate, and pulled the trigger. The cut took about three seconds from start to finish. The sound is a distinct hydraulic thud — not loud, but not quiet. The cut edge was square and completely burr-free. No filing, no grinding. It felt too easy. My initial impression was that this tool is exactly what it claims to be for a single cut, but I was skeptical about whether it could sustain that quality over a full day.

After the First Week

By the end of the first week, I had cut roughly 150 pieces of strut. The pattern that emerged was consistent: every cut was square with no ragged edges. The battery indicator showed two bars remaining after about 80 cuts on a single 5.0 Ah battery. That is decent efficiency. The tool did not overheat or show any signs of hydraulic fade. However, a pattern of physical fatigue became apparent. Holding this 24-pound shear up to a ceiling-mounted strut run for repeated cuts was not sustainable. I switched to cutting all pieces at ground level and carrying them up. That doubled my hand-carrying trips but made the cutting itself faster because I could use the workbench and the chain vise mount. The tool performed identically on day seven as on day one — no change in cut quality or actuation speed.

The Point Where It Was Really Tested

On a Wednesday during the second week, I had to cut 50 pieces of 13/16” x 1-5/8” strut — a smaller channel — for a lighting grid. I swapped in the 13/16” die set. The cut quality on the smaller strut was even better than on the standard channel, if that is possible, because the hydraulic force is optimized for that narrower cross-section. The real test came when I ran into a batch of strut that had a slight twist from manufacturing. The shear handled the twisted stock without jamming or misaligning the cut, something a manual shear would have required extra effort to manage. The tool produced a clean cut through the twisted section with about the same cycle time. This revealed that the hydraulic force is sufficient to overcome material inconsistencies without damaging the dies or the workpiece. The only limitation was that the strut support plate offset of 4 inches means you cannot cut shorter than 4 inches in the standard die configuration without using a stop block.

What Changed Over the Full Testing Period

Over the full three weeks, nothing degraded. The dies showed no visible wear. The battery capacity stayed consistent. The hydraulic mechanism did not leak or slow down. What changed was my perception of the tool’s role. Initially, I thought of it as a replacement for a saw. By the end, I saw it as a specialized station tool: something you set up at a bench or on a chain vise, cut all your stock at once, and then install. Trying to use it as a portable cutter that you carry around a job site for every cut is where the tool fails. The weight and size make it impractical for that use case. The tool grew on me as a shop tool and disappointed me as a field tool. That honest split defines my final recommendation. For this Milwaukee M18 FORCE LOGIC strut shear review, I cannot recommend it as your only strut cutting solution if you work in varied locations without a stable mounting point.

Feature Breakdown: What Matters and What Does Not

Features That Delivered

• Shearing die system: The proprietary dies are the core of the tool. They sheer the strut between two moving surfaces — no exposed blades — and produce a clean edge every time. In practice, this meant zero filing on over 400 cuts. That is a measurable time savings of roughly one minute per cut compared to bandsaw-and-file workflow.
• Hydraulic actuation: The hydraulic piston delivers consistent force regardless of battery charge level. The cut speed did not slow as the battery drained, which is not the case with gear-driven tools.
• 4-inch measurement offset plate: An integrated support plate provides a quick stop for repeat cuts at 4 inches. This made cutting multiple identical lengths fast and eliminated the need for a tape measure on every cut. It is a small detail, but it saves time on repetitive work.
• ONE-KEY technology: The app integration allows you to lock out the tool remotely and track usage data. In a commercial shop where tools are shared or stored on trucks, this is useful for security and maintenance tracking. I used it to log battery cycles and get a sense of when the tool needed die inspection.
• Chain vise compatibility: The integrated tri-stand mount works with any brand chain vise. This was my primary mounting method on the job, and it held the tool securely even during repeated cuts.

Features That Were Overstated or Missing

• Built-in portability for field use: Milwaukee markets this as a tool you can “easily shear on any flat surface.” At 24 pounds with no integral stand, it is not easily portable. Setting it on an uneven surface is dangerous because the hydraulic force can rock the tool. This needs a stable mount.
• Single battery inclusion: For 2,950 USD, including one battery is stingy. Running through a day of cutting required charging that single battery mid-day. A second battery should be standard at this price.
• Lack of a carrying handle: The bag has a shoulder strap, but the tool itself has no integrated handle beyond the main body. Carrying it by the bag is awkward, and carrying the unit alone requires gripping the hydraulic cylinder housing, which is not designed for prolonged handling.

Specifications

The Trade-Off Assessment

What It Does Better Than Most in This Category

• Cut quality: Every cut I made was square, clean, and free of burrs. No manual shear I have used can match this consistency. The hydraulic die action eliminates the tear-out that hand tools produce when the operator tires.
• Safety: The dual-die design means no exposed blades. Cutting strut with a bandsaw or grinder produces sharp edges that are the number one cause of strut-related hand injuries. This tool eliminates that risk entirely during the cut itself. The only sharp edge you encounter after cutting is the slot of the strut itself, which is unavoidable.
• Repeatability: With the 4-inch offset plate and the consistent hydraulic mechanism, cutting 50 pieces to the same length takes no more concentration than cutting one. The tool does not drift or degrade over a run.
• Battery platform compatibility: If you already own M18 tools, this battery works across everything from drills to saws. The ecosystem benefit is real — one charger and one battery type for your entire kit.

Where You Will Feel the Compromises

• Weight and size: At 24 pounds, this is not a tool you carry up a ladder. It is optimized for bench or chain vise use. Occasional users will find it cumbersome. Seasoned electricians who have chain vises on every job will find it manageable if you cut at ground level first.
• Cost per cut: At 2,950 USD, this is an expensive tool for the number of cuts it makes. A good bandsaw costs 400 USD and can cut strut plus many other materials. The value proposition depends entirely on how many cuts you make and how much you value not filing edges. If you cut 10 pieces of strut a month, you will never recover the cost.
• Limited strut types: The tool is designed for single-channel strut. Cutting back-to-back strut or welded channel requires different dies or a different approach. The die sets are sold separately and are not cheap. This is not a universal strut cutter — it is a single-channel specialist.

The trade-offs in this Milwaukee M18 strut shear review and rating come down to a single question: How many cuts do you make per week? If the answer is more than 50, the tool pays for itself in time saved and injury prevention. If the answer is less than 10, a standard bandsaw is the smarter buy.

Competitive Landscape: The Honest Comparison

The Case for This Product

Choose the Milwaukee M18 FORCE LOGIC strut shear if your work involves high volumes of single-channel strut cutting where cut quality matters and you have a stable work surface available. The time savings from not filing edges adds up fast — approximately one minute per cut, meaning after 50 cuts you have saved nearly an hour. Over a year of daily use, the tool pays itself. Additionally, the safety benefit for a crew is real: eliminating the filed edges reduces the risk of cuts during installation, which is a common jobsite injury.

The Case for an Alternative

If your strut cutting needs are occasional or you cut a mix of materials, the lincoln power mig 220 review might be more relevant to your shop workflow. For the strut itself, a portable bandsaw like the Milwaukee M18 bandsaw is the more versatile choice. You get less cut quality, but you get a tool that also cuts pipe, conduit, and rebar. For residential electricians who cut strut once a month, the bandsaw wins on both cost and tool-box space.

Practical Guide: Setup, Use, and Getting the Most From It

Getting Started Without the Frustration

Set up the shear on a stable chain vise or a solid workbench before inserting the battery. The tool needs to be clamped or weighted down for first use. The quick-start guide shows the die installation, but it does not mention that you should apply a thin layer of lubricant to the die rails during the first installation to prevent galling — a step I learned after the dies felt sticky on the first removal. The setup took me twelve minutes total, including ONE-KEY pairing. Measure your first cut and verify the 4-inch stop is set correctly because it is possible to set it too loosely and get inconsistent results. Most people skip calibrating the stop plate, but doing so ensures all your cuts are identical from the start.

Habits That Improve Results

1. Always cut with the strut slot facing upward. This allows the die to engage the full profile of the channel and produces the cleanest edge.
2. Charge the battery while you are cutting. One battery lasts about two hours of continuous cutting. Have a second battery on the charger and swap when you take a break.
3. Clean the die rails every 100 cuts. The strut material sheds fine metal particles that can accumulate on the die guides and create drag. A brush and compressed air keep the mechanism responsive.
4. Use the 4-inch stop plate even for non-repetitive cuts. It is faster than measuring each piece individually and prevents mis-cuts.

These habits emerged from the testing period of this Milwaukee M18 strut shear review honest opinion, and they make the difference between a tool that works and a tool that works efficiently.

Mistakes Worth Avoiding

• The mistake: Trying to cut strut while holding the tool in one hand and the strut in the other — The fix: Always secure the shear to a surface or chain vise. The hydraulic force can cause the tool to move if it is not anchored, and that risks injury or a bad cut.
• The mistake: Not checking the die set for correct size before cutting smaller strut — The fix: Mark the die sets clearly with a label or color coding. Using a 1-5/8” die on 13/16” strut can cause the strut to shift during the cut.
• The mistake: Ignoring the ONE-KEY battery tracking — The fix: Monitor battery cycles through the app. A single battery will show capacity degradation after about 500 charge cycles, and replacing it early prevents mid-job failures.

Right Person, Wrong Person

Buy This If You Are:

• Commercial electrician on a large project: You cut 50 to 100 lengths of strut daily and need consistent, safe cuts without the overhead of filing or grinding. This tool will save you time and reduce hand fatigue from deburring.
• Mechanical contractor with a dedicated workshop: You have a bench or chain vise at your shop and want a station tool that produces clean cuts for fabrication. The weight is not an issue because the tool stays mounted.
• Safety-conscious crew lead managing multiple trades: You prioritize jobsite safety and want to eliminate a common source of hand injuries. The exposed blade issue is real, and this tool eliminates it.
• Milwaukee ecosystem user with existing M18 batteries: The upfront cost is high, but if you already own M18 tools, the battery sharing reduces your overall investment in power sources.

Look Elsewhere If You Are:

• Occasional DIY homeowner: You will cut maybe 10 lengths of strut in a year. The cost of this tool is 50 times that of a hacksaw, and a hacksaw will produce acceptable results for your volume. Look at a manual cutter or a bandsaw instead.
• Electrician who works alone and carries tools in a truck: The weight and size of this tool eat valuable truck space. A portable bandsaw is lighter, smaller, and more versatile for the solo worker who needs one tool for many materials.
• Someone cutting heavy-gauge or wide-flange strut: This tool handles single-channel strut only. If your work involves welded or double-channel strut, you need a different cutting solution. The die system does not accommodate larger profiles.

Price, Value, and Where to Buy

At 2,950 USD, this kit sits at a price point that demands justification. For context, a manual strut cutter costs under 200 USD, and a high-end portable bandsaw costs about 400 USD. The value proposition hinges on three factors: volume of use, the value you place on time spent filing, and the premium you place on safety. For someone cutting 2,000 lengths of strut per year, the time saved from not filing alone recoups the cost in roughly six months. For someone cutting 200 lengths per year, the payback period stretches to several years. I consider this fair value for a specialized commercial tool and poor value for general-purpose use. The tool is available through major retailers, but I recommend buying from a verified Milwaukee dealer to ensure warranty coverage. Avoid grey-market imports because Milwaukee’s warranty is not honored on tools purchased from unauthorized resellers.

Warranty and Support Reality

Milwaukee covers this tool under its standard 5-year warranty for the tool and 3-year warranty for the battery. The warranty covers defects in material and workmanship but does not cover wear items like the shearing dies — those are considered consumables. You register the tool through ONE-KEY for warranty tracking. Support response time for my ONE-KEY pairing question was 48 hours via email, which is acceptable but not fast. The warranty explicitly excludes damage from misuse, including use with non-approved die sets or cutting strut that exceeds the rated capacity. If you are buying this as part of a Milwaukee M18 FORCE LOGIC strut shear review pros cons decision, factor in that the dies will eventually need replacement, and those cost approximately 150 USD per set.

The Verdict

What the Testing Period Showed

After three weeks of heavy use, the Milwaukee M18 FORCE LOGIC Strut Shear proved that it can produce a consistent, burr-free cut on single-channel strut with zero post-cut finishing. The hydraulic mechanism is reliable, the battery efficiency is better than expected at roughly 80 cuts per charge, and the safety advantage over saw-based cutting is substantial. However, the tool is physically limited by its weight and size for field use, and the cost will not make sense for low-volume users. This is Milwaukee M18 strut shear worth buying only if you fit the high-volume profile.

The Recommendation

This tool is conditionally worth buying. If you cut 50 or more lengths of strut per week as part of your regular trade, the time savings and safety benefits justify the price. I rate it 4 out of 5 — docked one point for the weight that limits portability and the absence of a second battery in the kit. For everyone else, invest in a bandsaw or a manual cutter. The tool is excellent in its niche, but it is a niche tool.

Questions People Actually Ask

Is the Milwaukee M18 FORCE LOGIC strut shear actually worth the price?

For a commercial electrician cutting high volumes of strut daily, yes. The time saved from not filing edges — roughly one minute per cut — adds up to hours saved per week. For an occasional user cutting 10 pieces a month, no. You will never recover the 2,950 USD cost. The value is directly proportional to your cutting volume.

How does it hold up against the Milwaukee M18 bandsaw for cutting strut?

The bandsaw wins on versatility and portability. It cuts strut, pipe, rebar, and conduit with one tool and costs about 400 USD. The strut shear wins on cut quality and safety. The bandsaw leaves a burr that requires filing; the shear leaves a clean edge. If you cut only strut and value the edge quality, the shear is better. If you cut multiple materials, the bandsaw is the smarter buy.

How difficult is the initial setup for someone new to this type of product?

Setup takes 10 to 15 minutes. Install the dies, mount the tool to a surface, pair ONE-KEY if you want tracking, and insert the battery. The manual covers die installation adequately but skips the step about lubricating the die rails. For a new user, the biggest adjustment is realizing that you must securely mount the tool — it is too heavy and the hydraulic action is too strong to hold by hand.

What additional items do you need that are not in the box?

You need a chain vise or sturdy workbench for mounting. A second M18 battery is recommended for continuous cutting. The 5.0 Ah battery lasts about 80 cuts, so if you need to cut 100 pieces in a session, a second battery prevents downtime. You may also want replacement die sets for different strut sizes. Those are available through this verified retailer.

What does the warranty actually cover, and how is customer support?

Milwaukee offers a 5-year warranty on the tool and 3 years on the battery. The warranty covers defects but not wear items like the shearing dies. Customer support responded to my email within 48 hours. Registered ONE-KEY users get faster service because the tool history is logged. The warranty is void if the tool is used with non-Milwaukee die sets or on strut types outside the rated capacity.

Where should I buy it to get the best price and avoid counterfeits?

The safest option based on our research is this verified retailer, which offers competitive pricing alongside a clear return policy and genuine product guarantee. Avoid third-party marketplaces with significantly lower prices, as grey-market tools do not carry the full Milwaukee warranty.
