These bits are made of precision-ground
high speed steel (HSS) that keeps a sharp edge longer, resists wear and possible overheating. Center brad point allows accurate positioning and prevents skating. Side cutting edges have relieved backs to reduce friction and produce smooth side walls. In diameter sizes 1/8" to 1/2" in 1/64" increments. Includes convenient storage box.
BONUS: Includes 4 additional small diameter HSS split point bits-1/16", 5/64",3/32"/ and 7/64" diameters. Great for screw pilot holes, miniature work and more !
