M40CO screw machine length drill bits are of a heavy duty design, recommended for use when drilling difficult materials and applications. They are manufactured from High Speed cobalt, suitable for drilling hard materials including tool steel, and have a bronze oxide finish to stop workpiece material from sticking to the cutting surfaces of the tool, so you get a more accurate hole. The 135 degree split point is an aid to self-centering, so no drill wander over the workpiece surface, and reduces the force needed to drill down. M40CO drill bits are available in fractional sizes from 1/16in to 3/4in in 1/64in increments.
