Double End Drill Bits
This is one case where being self-centered is not a bad thing. For quick penetration of thin metal in machining projects, these self-centering, split-point drill bits are great for making holes in sheet metal, setting holes for rivets, or making pilot holes. And with cutting edge on either side of the bit, these metal drill bits ensure you’ll go longer without having to sharpen or replace them. Products vary by application, length and other considerations. For more quick cutting bits, see our spade blades and indexable drill inserts.
