ULTIMATE ROUGH-IN PRODUCTIONFor fleet managers and trade specialists, the Milwaukee 49-22-0130 7-Piece Selfeed Bit Kit represents the pinnacle of high-volume boring efficiency. Engineered specifically to tackle the rigors of commercial rough-ins, these bits leverage an aggressive lead-screw design that effectively pulls the cutter through dimensional lumber with zero manual feed pressure. This allows your team to maintain a rapid pace when routing plumbing lines or electrical conduits, while simultaneously extending the runtime and motor life of your high-torque drill fleet by reducing mechanical resistance. / SELF-FEEDING AGGRESSION: The optimized lead screw geometry automates the drilling process, ensuring the bit stays engaged and productive even in the toughest dense-grain woods. / RENEWABLE PERFORMANCE: Unlike disposable alternatives, these heavy-duty bits are designed to be resharpened, providing a massive return on investment over the lifecycle of the kit. / ANTI-SLIP HEX SHANK: The 7/16" hex shank provides a locked-in connection for high-torque drills, eliminating the chuck slippage that often plagues round-shank accessories. / RUST-INHIBITING COATING: Every bit is treated with a specialized surface finish to prevent corrosion and ensure clean chips for smoother, faster material ejection.
