R88CO drills, manufactured to NAS907 type D standard, have a heavy duty design, recommended for use in difficult materials and applications, and are manufactured from premium High Speed cobalt, for drilling hard materials including tool steel. They are available in fractional sizes from 1/16 inch to 1/2 inch in 1/64 inch increments.
The 135 degree split point helps with self-centering and reduces the push force needed, whilst the bronze oxide finish prevents workpiece material from sticking to the cutting edges of the tool, for more accurate holes.
