M51CO HSS-E Bronze 135D Taper Length Drill Long ANSI 29/64 in

With a heavy duty design, recommended for use in difficult materials and applications, M51CO taper length drill bits are manufactured from Premium High Speed cobalt for drilling hard materials, including tool steel. With a 135 degree split point to help with self centering and reduce the push force needed, the drills also have a bronze oxide finish which prevents workpiece material from sticking to the cutting surfaces of the tool for clean and accurate holes. M51CO HSCo taper length drill bits are available in a range of fractional diameters, starting at 1/16 in and going all the way up to 1 in, in increments of 1/64 in.
