These bits pay for themselves the first time they prevent your bit tip from skidding across a finished surface. The tips have a coating of fine diamond grit that increases friction between the driver and screw head to significantly reduce cam-out. Each bit is milled from chrome molybdenum vanadium tool steel, hardened to Rc57-59, and nickel-plated to resist corrosion.

Made in Germany, they are 1" long with standard 1/4" hex shanks. For long screws or the slot bits, we recommend using a retracting screw holder (sold separately). Its sleeve holds the screw in line with the bit and retracts as the screw is driven. Extends from 4 3/4" to 7 1/2" long.
