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.

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.

FLEXTORQ bits are engineered for durability. This latest generation from DEWALT redefines fitment and performance with overhauled tip geometries. The newest DEWALT FLEXTORQ PH2 bits deliver 100% more more→screws per bit. Every FLEXTORQ bit features a FLEXTORQ Zone designed to absorb impact for longer life. Save time and find the right bit with new highly-visible laser-etched size. Each FLEXTORQ bit is IMPACT READY with a 1/4-in hex shank for use in impact drivers and drills.
