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.

Power through masonry, concrete, rock, and more with DEWALT Hammer Drill Bits. Featuring rock carbide tips that maximize surface contact for extended bit life and a 4-flute design that cleans debris w more→hile you work. 3 flats on the shank eliminate bit slippage.

The Milwaukee Shockwave 7-piece Shockwave Impact Magnetic Drive Guide Set is engineered for extreme durability and up to 30x life. The Milwaukee magnetic drive guide set features optimized Shockzones more→that absorb peak torque and prevent them from breaking. Each Custom Alloy76 Steel drive guide has a stainless steel sleeve that slides over the fastener for improved stability. The drive guide barrels have laser etched depth gauges for increased fastener control.

The Shockzone is optimized for each tip type and length of driver bit to absorb peak torque and prevent breaking. The Custom Alloy76 has a customized steel and heat treatment per tip type to extend the life of the driver bits, providing up to 50X life vs. competitive impact driver bits. The Shockwave driver bits are built to deliver extreme durability for the most demanding applications.

For rotary drilling only. Includes 5/32 pilot bit which must be used first. Ideal for drilling porcelain tiles up to a scratch hardness of 8. The drill bit will not walk, tape or center punching is no more→longer needed. Flat bottom parabolic flute ensures fast and efficient removal of drill dust and prevents clogging. Cuts nice, clean holes with very little or no chipping; operate drill motor 400-600 RPM.
