Description

Authorized Dealer Badge DEWALT logout

Shop the DEWALT DCS571B compact cordless circular saw engineered to slice through 2x dimensional framing timber inside narrow crawl structural gaps. This 20V MAX XR brushless power tool drives a 4-1/2 inch thin-kerf blade through an integrated high-performance metal bevel gear mechanism. Delivering up to 45-degree angle bevel adjustments while maintaining an active electronic blade brake, it resolves heavy material binding and handling limitations across overhead wood trimming and sub-floor sheathing projects.

**Battery and charger sold separately.

Best Used For:

  • Sheet Good Ripping: Slicing down 3/4-inch oriented strand board (OSB) and interior plywood sheets cleanly over continuous linear paths.
  • Dimensional Lumber Sizing: Executing true 90-degree crosscuts through 2x structural timber framing elements and 45-degree cuts on 1x materials.
  • Confined Space Trimwork: Maneuvering inside narrow wall studs or roof rafters to execute trim alterations where standard circular tools cannot fit.

Key Performance & Safety Features

  • High-Efficiency Brushless Motor: Advanced internal power plant optimizes structural performance parameters to run through 339 linear feet of OSB per charge.
  • Compact Metal Bevel Drive: Specialized gear geometry houses high turning force inside a slim profile frame to slice full 2-inch structural wood thicknesses.
  • Electronic Blade Brake System: Automated safety friction circuitry stops spindle inertia instantly upon trigger release to safeguard the workspace.
  • Extended Rear Handle Stalk: Elongated tool body balancing layout stretches forward reach and straightens hand alignment during long rip tracking.
  • Vacuum Hood Integration: Removable dust collection adapter links directly with external utility extraction tubes to capture fine chips indoors.
