The Milwaukee Shockwave Impact Duty Phillips Bits are engineered to be the Most Durable, Best Fitting driver bits on the market. The Phillips bits feature Wear Guard Tip for increased wear resistance more→which protects the fit over the life of the bit. The impact driver bits have and optimized Shockzone for each tip type and length of driver bit to absorb peak torque and prevent breaking. The Custom Alloy76 Steel is customized and heat treated per tip type to extend the life of the driver but by up to 50X vs. competitive impact driver bits. The Milwaukee Shockwave Impact Duty driver bits are built to deliver extreme durability for the most demanding applications.

Diablo's new 2-cutter Self Feed Bits are designed to strict tolerances in the heat forging manufacturing process resulting in energy efficient drilling with up to 2X life per battery charge. Diablo Se more→lf Feed Bits 2-cutter design and an aggressive low thread count feed screw deliver up to 2X more holes per charge. The replaceable feed screw features a pull out stop mechanism that prevents the screw from slipping out when the bit is removed from the material. The combined innovative engineering of Diablo Self Feed Bits makes them the ideal choice for making holes up to 2X faster in soft woods.

While most screw driving bits are simply compatible with impact drills and drivers, Irwin Impact Performance Series fastener drive bits are engineered for maximum durability and long life with impact more→drivers. These bits are forged rather than milled, so they fit fasteners more precisely, which reduces stripping and increases the life of the bit itself - Irwin's Impact Performance Series bits have three times longer life than traditional bits.
