#12 Cobalt Oxide/Gold Finish 135 Deg. Split Point Heavy-Duty Jobber Drill

Manufactured to NAS907 type D standard, R89CO drills are made from High Speed cobalt for drilling hard materials such as tool steel. They have a bronze oxide finish to stop workpiece material from sticking to the cutting edges of the tool for cleaner, more accurate holes and a 135 degree split point to help with self-centering and reduce the amount of force needed to drill into the workpiece. Available in wire gauge sizes from 52 to 3, R89CO are heavy duty drills, recommended for difficult materials and applications.
