Jobber-length drill bit made from M2 high speed steel with Irwin's 135-degree self-centering split point. The precision-ground tip starts cleanly on flat and curved surfaces without walking, so you can drill accurately without punching a pilot hole first. The bit has a black body and gold flute.

Overall length: 4-1/2". Flute length: 3-3/16". Three-flatted shank gives the chuck a better grip and helps stop the bit spinning.
