DeWALT 20V MAX 6-1/2 in. Cordless Circular Saw (Bare Tool) - DCS391B is a high-performance cordless circular saw engineered for professionals and serious DIYers who need reliable cutting power without the restriction of a cord. Driven by a 5,150 RPM motor and fitted with a 6-1/2 in. carbide-tipped blade, this saw handles demanding rip cuts, crosscuts, and bevel cuts through framing lumber, sheathing, and dimensional materials with consistent speed and accuracy. The tool-only configuration means you can pair it with your existing DeWALT 20V MAX lithium-ion batteries, keeping your cordless system unified and your investment efficient.

Key Features

• 5,150 RPM motor - delivers sustained power and blade speed through tough cuts in framing lumber and engineered wood, reducing bogging and keeping your workflow moving on the jobsite.
• High-strength magnesium shoe - combines lightweight construction with jobsite-grade durability, so the saw stays precise cut after cut without adding unnecessary fatigue to your arm over a long work day.
• 0 to 50 deg. bevel capacity with preset stops at 0 deg. and 45 deg. - gives you versatility for everything from square cuts to aggressive bevels, letting a single saw handle a wide range of framing and finish applications.
• Optimized rubber overmolded D-ring comfort grip - positions your hand in a natural, controlled hold that reduces strain during extended use and keeps the saw balanced through long cut runs.
• Left-side blade placement - puts the blade on your dominant sightline when cutting right-handed, improving cut-line visibility and reducing the chance of drifting off your layout mark.
• Tool-free blade changing - lets you swap blades quickly without hunting for a wrench, saving time during blade changes between materials or when a blade dulls mid-job.
• Direct drive motor configuration - transfers power efficiently straight to the blade with fewer mechanical components, contributing to the saw's 7.58 lb. overall weight and compact footprint.
• Maximum cut depth of 2-1/8 in. at 90 deg. and 1-5/8 in. at 45 deg. - covers standard 2x dimensional lumber in a single pass at both square and angled cuts, eliminating the need for multiple passes on common framing tasks.

Why This Product

• Fits your existing 20V MAX battery system - if you already own DeWALT 20V MAX lithium-ion batteries, this bare tool lets you add a circular saw to your arsenal without paying for a redundant battery and charger, keeping your overall tool investment lean.
• Aggressive bevel range for versatile cutting - the 0 to 50 deg. bevel capacity goes beyond the standard 45 deg. stop found on many saws, giving you access to steeper angled cuts that are useful for compound trim work and specialized framing angles.
• Lightweight magnesium shoe built to last - unlike aluminum or plastic shoe alternatives, the magnesium construction resists bending and warping under jobsite stress, which directly protects your long-term cut accuracy and square reference surface.
• Compact dimensions for tight-space maneuverability - at 13.78 in. long and 8.94 in. wide, the saw is sized to work in framing bays and on staging where larger worm-drive or rear-handle saws become awkward.
