Key Features
Big Cordless CapacityThis DEWALT sliding miter saw cuts up to 14 inches horizontally, with capacity for 6-1/2 inch baseboard standing up and 6-1/2 inch crown nested. That gives trim crews and remodelers the reach of a serious 12 inch saw without dragging a cord around the job. Runtime That MattersRegenerative braking technology and a bevel gear transmission are built to reduce wasted power. In real terms, that means more cuts per charge and less downtime when you are moving from room to room or working where power is not convenient. Cleaner Cut StationWith integrated WIRELESS TOOL CONTROL support and dust collection rated to capture up to 97% of dust, this saw helps keep the work area under control. That matters when you are cutting trim indoors and do not want cleanup turning into half the job.
Overview
The DEWALT 20V MAX XR 12 in. Double Bevel Sliding Miter Saw Kit, model DCS785WW1, is a cordless 12 inch sliding compound miter saw built for accurate crosscuts, miter cuts, and bevel cuts on trim, framing components, and general jobsite stock. This is a sliding miter saw designed for precision trim work, finish carpentry, and high-capacity crosscutting. If you need a full-size saw but want to stay on the DEWALT battery platform, this kit gives you a serious cordless setup with the saw, battery, charger, blade, and jobsite accessories in one box.
What separates this saw from a lot of cordless options is capacity. DEWALT calls it their largest cut capacity 20V MAX miter saw, and the numbers back that up: it cuts up to 14 inches horizontally, handles 6-1/2 inch baseboard standing up, and cuts 6-1/2 inch crown nested. For trim installers, remodelers, and punch list crews, that means fewer workarounds and less flipping material to finish a cut. It is also built to produce up to 371 cuts in 3-1/4 inch MDF base molding and up to 153 cuts in pressure treated 4×4 timber per charge with the included DCB2108 battery, so this is not a light-duty cordless novelty.
DEWALT also put real thought into efficiency. Regenerative braking technology is there to help extend runtime, and the bevel gear transmission is designed to minimize power loss through the system. That matters because cordless miter saw performance is not just about peak power, it is about how much usable work you get before swapping packs. On a mobile setup or in a finished space where outlets are limited, better efficiency translates directly to fewer interruptions.
Accuracy features are jobsite-friendly instead of fussy. The CUTLINE blade positioning system gives you an adjustment-free cut line indication, so you can line up fast without depending on a laser that needs recalibration. Quick bevel adjustments at 22.5 degrees and 33.9 degrees with the included bevel pawls also make sense for finish work where repeatable angle changes are common. Add in simple touchpoints for depth of cut, miter, and bevel settings, and this saw is set up to keep you moving instead of hunting for controls.
Dust control is another strong point. DEWALT rates the system to capture up to 97% of dust during use, and the integrated WIRELESS TOOL CONTROL setup can trigger a connected vacuum to run when you pull the saw trigger. That is useful in remodel work, interior trim installs, and occupied homes where keeping dust down is not optional. The kit includes both a dust bag and a non-Airlock vacuum adapter, though the vacuum itself is sold separately.
From a portability standpoint, this is still a full-capacity 12 inch slider, but DEWALT kept the tool-only weight to 51.7 pounds and added convenient carry handles. That is still a two-hand lift for most people, but it is manageable for jobsite moves and truck-to-room hauling. The included stabilizer bar, base extensions, material clamp, and blade wrench round out the package so the saw is ready to work right away instead of sending you back for small essentials.
Battery compatibility is a big reason this kit makes sense for existing DEWALT users. It works with the full range of DEWALT 20V MAX and DEWALT FLEXVOLT batteries, so crews already invested in the platform can share packs across drills, impact drivers, saws, and this miter saw. DEWALT specifically notes that for best performance, an 8Ah or higher battery is recommended, and this kit includes the DCB2108 8Ah battery to match the saw’s intended use.
Who should buy it? This is a strong fit for finish carpenters, remodelers, trim crews, deck builders, and general contractors who need a cordless miter saw with full-size capacity. If your work is mostly small punch cuts at a bench, this may be more saw than you need. But if you want a serious cordless miter saw that can handle base, crown, wider stock, and jobsite movement without giving up the battery platform, this one earns its space in the trailer.
Cut Full-Size Trim Without a Cord
The big selling point here is simple: you get true 12 inch sliding miter saw capacity in a cordless platform. That makes a difference when you are installing trim in finished spaces, moving room to room, or working in new construction before permanent power is in place.

DEWALT 20V MAX XR 12 in. Double Bevel Sliding Miter Saw Kit for Pros Who Actually Need Capacity
This is the cordless miter saw for guys who do not want to give up full-size cut capacity just because the jobsite setup keeps changing.
- Who it’s for: Trim carpenters, remodelers, and contractors who need a 12 inch sliding miter saw for base, crown, wider stock, and room-to-room mobility.
- Why it stands out: The big win is capacity plus battery compatibility. You get up to 14 inch horizontal cuts, double bevel capability, strong runtime claims, and support for the full DEWALT 20V MAX and FLEXVOLT battery lineup.
- Worth knowing: It is still a full-size slider, so this is not the smallest saw to stash in a van. But if your work justifies the reach, the included 8Ah battery and dust-control setup make this a well-thought-out kit instead of a stripped-down bare tool.
