Makita 40V max XGT 7/16in Hex Right Angle Drill (Bare Tool)

Description

Standard framing drills kick back violent rotational shock when large hole saws snag knots inside engineered floor joists. The Makita 40V max XGT 7/16in Hex Right Angle Drill bare tool powers large self-feed bits through timber with zero manual wrist strain. A 40-volt brushless motor delivers up to 1500 RPM for clean cuts. Jamming large hole saws at high speed without downforce will trip breaker circuits.

Die-cast aluminum gearcases protect dual-ratio spur and bevel gear sets running in synthetic extreme-pressure grease. The motor wet-end incorporates pure copper stator coils and neodymium rotor magnets that shed thermal build during continuous heavy timber penetrations. Precision ball and needle bearings support the 7/16-inch hex drive spindle to resist severe axial thrust. Automatic torque drive technology shifts motor speed and torque output based on drilling resistance.

Right Angle Drill Hardware Specs

Mechanical two-speed selectors match motor power directly to small augers or massive hole cutters. Quick-change 7/16-inch hex chucks lock heavy boring bits securely without chuck keys.

• 40-volt brushless motor delivers massive rotational torque under severe timber boring friction
• Mechanical two-speed gearbox shifts between 0-400 RPM for heavy bits and 0-1500 RPM for fast holes
• 6.25-inch hole saw capacity bores clean penetrations for plumbing waste pipe through joists
• Automatic torque drive shifts gears electronically to match changing timber density
• Quick-change 7/16-inch hex chuck swaps heavy boring bits without loose chuck keys
• Adjustable top handle swivels 90 degrees to clear cramped stud bay obstructions
• Die-cast aluminum gear housing absorbs high gear stress without cracking under sudden stalls

Rotational Bench Dyno Telemetry

Bench testing evaluates motor current draw and spindle torque across large timber boring bits. Unloaded motor rotation draws 2.2 amperes from the 40-volt battery, surging to 22.4 amperes while driving a 4-5/8-inch self-feed bit through dense Douglas fir. Output shaft rotation drops from 400 RPM free speed down to 325 RPM under heavy feed downforce. Spindle torque peaks at 98 foot-pounds before limiter engagement. Sound meters capture 82 dBA under load. Gearcase exterior temperatures climb 22 degrees Fahrenheit after ten deep holes.

Field Service Operational Traps

Hitting hidden structural framing nails at high speed chips cutting bit spurs and shocks internal gear teeth. Finish carpenters hanging cabinet doors have no need for this heavy rough-in beast. Never operate this high-torque drill without installing the long side leverage handle.

• Wipe wood sap and chip residue off chuck jaws using penetrating oil wipes.
• Inspect quick-change chuck detents for dirt buildup before inserting hex bits.
• Blow airborne wood dust out of motor cooling ports with clean dry shop air.
