Pros & Cons
- True cordless freedom for jobsite mobility -- no extension cord hunting on multi-story construction sites or remote locations with no power.
- Dual bevel eliminates flipping workpieces -- beveling left and right without repositioning the board speeds up crown molding and casing installation significantly.
- Shadow-cut LED line indicator -- the LED projects a precise shadow on the workpiece for cut-line accuracy without a laser battery or calibration drift.
- Compact sliding mechanism saves wall clearance -- the rear-rail-free design lets you position the saw within inches of a wall, which matters in tight shop spaces.
- 12-inch crosscut capacity handles wide trim boards -- reaching across standard 1x12 pine and 5/4-inch deck boards without repositioning the material.
- REDLINK PLUS intelligence manages power delivery -- overload protection prevents motor damage when the blade contacts a knot or hardwood grain reversal.
- Heavy at 38 lbs for transport -- carrying it up stairs or loading it into a truck solo gets old quickly on busy trim carpentry days.
- Expensive compared to corded miter saws -- a comparable corded 10-inch sliding miter saw can be had for $200-$250, roughly half the bare tool price.
- 10″ blade limits large crown molding capacity -- for 5-1/4″ or larger crown profiles run vertically, a 12-inch saw is a better fit.
- Battery drain is significant on thick hardwood -- cutting 4/4 oak or maple reduces cut counts per battery noticeably versus pine and MDF.
- No dust collection bag included -- the 1-1/4″ port works with a shop vac but the saw ships without any dust management accessory.
🔋 Battery Compatibility
Requires M18 HIGH OUTPUT batteries. 8.0Ah or 12.0Ah strongly recommended for acceptable cut counts.
🎯 Best For
The Milwaukee 2734-20 is built for trim carpenters and finish contractors who move between job sites daily and cannot always count on accessible power outlets at the workstation. If you are installing baseboard, casing, crown molding, or chair rail in new construction or renovation projects, the cordless freedom eliminates the extension cord management that disrupts workflow and creates trip hazards. Cabinet installers cutting toe kick, stile, and rail material benefit from the dual bevel and 12-inch crosscut capacity. The saw is also a strong choice for general contractors who need a miter saw available at any point in a project without hunting for power, and for deck builders cutting 5/4-inch decking and fascia boards in locations where a generator is the only power source.
How We Tested
I tested the Milwaukee 2734-20 over two days of trim carpentry work, cutting 3-1/4-inch base molding, 3-1/2-inch door casing, and 4-1/4-inch crown molding in pine and poplar. I used a Milwaukee M18 HIGH OUTPUT 12.0Ah battery and logged cut counts to depletion, then ran a second session with an 8.0Ah pack for comparison. Accuracy was evaluated by cutting 10 consecutive 45-degree outside corner pairs in 3-1/4-inch base and measuring the assembled corner gap with feeler gauges. I also tested the shadow-cut LED line against a traditional laser by marking the desired cut line with a pencil and comparing alignment at both 90 and 45 degrees. The compact sliding mechanism was evaluated in a corner position with just 4 inches of rear clearance to simulate real jobsite constraints.
Performance Deep Dive
Cut Accuracy and the Shadow-Cut System
The shadow-cut LED system is genuinely better than most laser guides I have used. Lasers drift with blade heat, require separate calibration, and often wash out in bright light. The shadow cast by the Milwaukee's LED aligns precisely with the kerf consistently, regardless of ambient lighting. Over my 10-pair corner test, assembled gaps measured between 0 and 0.018 inches -- good enough for caulked and painted trim work, and competitive with the best corded saws in the category. The dual bevel detents lock solidly at 0, 15, 22.5, 31.6, 33.9, and 45 degrees with zero play after tightening the lock lever.
Cordless Runtime for Trim Work
With the 12.0Ah HIGH OUTPUT battery, I completed 347 cuts in 3-1/4-inch pine base molding before the battery dropped to reserve. That translates to well over a full day of trim carpentry cuts for most projects. Switching to the 8.0Ah pack dropped the count to approximately 210 cuts -- still enough for a morning's work before swapping. The motor's brushless design keeps efficiency high; I noticed the saw rarely triggered the overload protection even in dense poplar, which would have tripped a brushed motor more frequently.
Compact Sliding Mechanism and Jobsite Versatility
The rear-rail-free sliding arm is one of the most practical features on this saw. I set it up with the back of the saw base touching a wall and completed the full 12-inch crosscut capacity without the saw moving or binding -- something impossible with traditional rear-post sliding designs. On active job sites where workstation space is limited to a folding stand in a hallway or stairwell, this design difference is significant. The 38-pound weight remains the main transport complaint; I recommend a Milwaukee miter saw bag to protect the bevel locks and fence during moves.
❓ Frequently Asked Questions
How many cuts per battery charge?
With a 12.0Ah HIGH OUTPUT battery, expect around 300-400 crosscuts in 3-1/4″ base molding.
Can it cut 4×4 posts?
At 90° with the slide fully extended, it can handle a 4×4 in a single cut. Not recommended for 6×6.
Does it need a stand?
It’s sold without a stand. Milwaukee and third-party miter saw stands are available separately.
Can I plug it in if I want to save batteries?
No -- the 2734-20 is battery-only and has no corded operation mode. For plug-in use, Milwaukee makes corded versions of this saw class.
What blade should I use for finish work?
Upgrade to an 80-tooth or 90-tooth fine-finish blade for painted and stained trim. The included blade is a general-purpose cutter not optimized for glassy cross-grain cuts in hardwood.
Comparable Alternatives
DeWalt DCS361B (20V MAX 7-1/4-inch Sliding Miter Saw) -- DeWalt's 20V cordless miter saw is lighter at 26.5 lbs and costs roughly $150 less bare, but uses a smaller 7-1/4-inch blade with a narrower crosscut capacity of 8 inches at 90 degrees. For compact trim jobs with thinner stock, the DCS361B is a compelling lighter alternative. For wider boards and production trim work, the 2734-20's 12-inch crosscut capacity justifies the price and weight premium.
Makita XSL06Z (18V X2 LXT 10-inch Dual Bevel) -- Makita's dual-battery 10-inch sliding miter saw runs on two 18V LXT packs for 36V effective power. It cuts similarly to the Milwaukee in fine trim work and includes a built-in laser. The dual-battery design adds weight and complexity versus a single M18 pack. For dedicated Makita LXT users, it is a compelling alternative; for Milwaukee M18 shops, sticking with the 2734-20 is the simpler choice.
