The DeWalt DCG412B 20V MAX 4.5-Inch Cordless Angle Grinder Bare Tool is an industrial portable metalworking power tool engineered for high-speed cutting, weld surface grinding, rebar flush trimming, and concrete scoring across commercial jobsite environments. Driven by a high-output 20-volt motor reaching 8,000 RPM, this tool accepts 4-1/2-inch and 5-inch grinding wheels and cutoff discs using a tool-free quick-change wheel release flange. Equipped with a tool-free adjustable guard, a 2-position anti-vibration side handle, and a two-finger trigger switch with a lock-off safety lever, this cordless power tool operates on any DeWalt 20V MAX lithium-ion battery platform. **Battery and charger sold separately.

  • Concrete & Masonry Tuckpointing: Scoring concrete control joints, slicing masonry pavers, and trimming ceramic tile backerboard using diamond blades.
