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.

Diablo's driver bit range delivers maximum performance, extreme durability and up to 50x longer life when installing and removing fasteners. An optimized tip design provides a strong, precise grip tha more→t reduces wear, stripping and slippage. Torque Resistant Design absorbs torque for less stress at the tip when tightening and removing nuts and screws. This range is Impact Strong, delivering increased shank stability and durability in cordless and corded impact and drill drivers.

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.
