DEWALT Angle Grinder DCG405B 20V 4.5 Inch Corded Replacement Cordless Skin (9000 RPM Brushless Slide Switch Kickback Brake Power Loss Reset Bare Tool)

Halt Wheel Rotation under Two Seconds during Sudden Bind Ups and Prep Structural Weld Lines Safely

The DEWALT DCG405B 20V MAX* XR® Brushless 4.5-Inch Angle Grinder is an industrial-grade cordless metal fabrication instrument engineered to deliver up to 9,000 RPM of rotational velocity. This heavy-duty power tool features an advanced electronic brake that stops wheels in under two seconds and a specialized dynamic kickback sensor to shut down the motor during severe wheel pinches or stalls. Outfitted with a slim ergonomic gear housing, a secure safety slide switch, and a Power Loss Reset® circuit, this compact layout tool optimizes mobile productivity across commercial construction grids. **Battery and charger sold separately.

Best Used For:

• Commercial Rebar Cutting: Slicing rapidly through thick concrete reinforcing iron rods and heavy mesh layouts unassisted on structural project slabs.
• Structural Steel Beveling: Removing mill scale, cleaning slag, and beveling heavy carbon steel plates prior to multi-pass welding sequences.
• Restricted Mechanical Grinding: Smoothing rough metal edges and trimming hanging hardware struts inside tight utility chaseways or narrow ceiling runs.

Key Performance & Safety Features

• XR Brushless Motor Efficiency: High-performance drivetrain deletes carbon brush wear cycles while maintaining consistent operational speed profiles under heavy feed pressures.
• PERFORM & PROTECT™ Kickback Brake: Electronic deceleration system stops abrasive wheel movement within 2 seconds if an internal binding index is breached.
• Power Loss Reset® Circuitry: Smart electrical monitor blocks unexpected motor self-starting if a fresh battery pack is inserted while the slide switch sits engaged.
• Ergonomic Slimline Grip Frame: Reduced chassis diameter allows operators to balance the tool securely while wearing thick leather welding gloves.
• Two-Position Side Control Handle: Auxiliary stabilizing handle mounts on either side of the cast metal gear box to optimize tool tracking leverage.

Technical Specifications

PRO-TIP: When dropping this cordless grinder into tight structural channel cuts, let the 9,000 RPM velocity establish its scoring kerf naturally before leaning into the frame. Maintaining a straight feed alignment line prevents binding conditions entirely, ensuring the integrated Kickback Brake remains passive while extending cutting disc life.
