DEWALT Stud and Joist Drill DCD446B 20V MAX XR Brushless Right Angle Drill (Keyed Chuck Anti Rotation System Wood Boring Electricians Bare Tool)

Mitigate Jobsite Bind-Up Risks and Maintain Continuous High-Torque Mechanical Boring

The DEWALT DCD446B 20V MAX XR Brushless 1/2-Inch Right Angle Stud and Joist Drill is a compact cordless wood-boring power tool engineered to deliver up to 1,845 max watts out for rigorous framing installations. This heavy-duty right-angle unit drives up to a 4-inch hole saw or a 2-9/16-inch self-feed bit through dense framing timber while spinning at a maximum speed of 1,250 RPM. Outfitted with an advanced electronic Anti-Rotation System that monitors rotational motion and automatically cuts motor power during excessive tool twist, this bare tool maximizes trade productivity for structural electrical and plumbing layouts.

**Battery and charger sold separately.

Best Used For:

• Plumbing Layout Openings: Boring large 4-inch structural clearance holes using hole saws through joists and studs to pass commercial drain lines.
• Electrical Conduit Channels: Drilling serial 2-9/16-inch or auger pass-through routes cleanly across structural framing lumber to run distribution cabling.
• Confined Framing Intersections: Executing high-torque right-angle bit entries inside restrictive stud bays, low overhead clearances, and tight corner layouts.

Key Performance & Safety Features

• Anti-Rotation Protection Technology: Senses sudden torque adjustments and immediately kills tool power, alerting the user via a red structural LED indicator light.
• High-Efficiency Brushless Motor: Delivers advanced motor lifetime and maximizes continuous-run power output under extreme resistance.
• Large Drilling Diameter Threshold: Sustains deep cutting capacity to run up to 4-inch hole saws or 2-9/16-inch self-feed bits safely.
• XR Battery Power Enhancement: Harnesses intelligent power scaling to produce up to 79% more max watts out when stepping up to a DCB2108 pack over basic batteries.
• Tool Connect Smart Integration: Outfitted with an on-board chip pocket configured to accept DCE042 smart tags for effortless cloud tracking on the site manager app.
• Industrial Keyed Chuck Assembly: Utilizes a heavy-duty 1/2-inch keyed chuck interface to guarantee a firm lock and prevent bit slip under load.

Technical Specifications

PRO-TIP: Although the integrated electronic Anti-Rotation System acts quickly to cut powertrain rotation when a bit binds, always maintain a firm two-handed stance with your secondary support arm extended against the structural framing joists. Providing a reliable structural bracing point allows the high-torque brushless gears to advance with zero lever flex.
