RAPID ROUGH-IN BORING DOMINANCEWhen your crew is staring down a massive rough-in, the Milwaukee 49-22-0135 Selfeed Bit Kit provides the mechanical advantage needed to blast through dimensional lumber without the fatigue of manual pushing. These bits are engineered for high-volume, repetitive drilling where clean holes and speed are the primary metrics for jobsite ROI. By utilizing an aggressive center lead screw, the bit self-feeds through the timber, allowing the motor to do the work while you maintain control, ensuring every conduit and pipe run passes through a perfectly gauged aperture. / AUTOMATIC FEEDING: The high-pitch center feed screw pilots the bit and pulls the cutter through the wood automatically, requiring zero downward pressure from the operator. / SHAVED RADIUS PRECISION: Inside cutting planes shave the hole radius to produce clean, smooth holes that won't snag pipes or wires during installation. / INDUSTRIAL LONGEVITY: Each bit is fully resharpenable and coated with a rust inhibitor, ensuring these assets stay in your fleet for years of service rather than being treated as disposables. / HIGH-TORQUE ENGAGEMENT: The 7/16 inch hex shank provides a massive gripping surface for the drill chuck, eliminating bit slippage even when boring through dense knots.
