About this product
Achieve Fast Accurate Multi-Material Slicing in Tight Spaces with Advanced Directional Control
The DEWALT DCS438B 20V MAX XR Brushless Cordless 3-Inch Cut-Off Tool delivers clean, high-velocity sectioning through dense masonry, porcelain tile, metal sheeting, and drywall. Driven by an industrial brushless motor that produces 550 Max Watts Out (MWO) and an un-loaded spindle velocity of 20,000 RPM, this compact utility saw allows operators to execute straight plunge cuts up to 0.7 inches deep. The power head features a mechanical forward and reverse directional switch to divert sparking away from critical lines, coupled with an adjustable dust-extraction shroud that integrates smoothly into standard site vacuum equipment.
Best Used For:
- Electrical Conduit and Pipe Fitting: Cleanly trimming EMT conduit, structural copper lines, and PVC piping without rough burrs.
- Ceramic Tile and Masonry Installation: Scoring or shaping custom porcelain tiling, stone backsplashes, and cement backer boards accurately.
- HVAC Sheet Metal Modification: Slicing straight or curved access paths directly through steel ventilation ductwork and flashing.
Key Performance & Safety Features
- High-Torque Brushless Powerplant: Electronic brushless design maximizes multi-material cutting efficiency up to 550 MWO while dropping internal thermal wear patterns.
- Bi-Directional Forward and Reverse Modes: Switchable rotation paths optimize cutting angles to safely direct active sparks and chip streams away from the operator.
- Removable Dust Shroud with AirLock Connection: Integrated cutting guard connects directly to commercial extractors via a locking flange to keep work surfaces dust-free.
- Tool-Free Cutting Depth Shoe: Precision stamped index ring features clear Imperial markings to facilitate micro-fine cutting depth alterations instantly.
- Universal Blade Adaptor Geometry: Accommodates standard 3-inch cutting wheels with a 3/8-inch arbor, alongside an adapter ring for 7/16-inch wheel configurations.
- Asset Management Site Readiness: Designated internal dock receives an automated Tool Connect monitoring chip (sold separately) for quick fleet tracking tracking options.
