Coolant Tungsten Carbide Rods with oil duct

Both carbide rod with straight coolant holes and helical coolant holes are supplied. Different grades are also available in stock. The internal cooling hole can provide much more efficient chip evacuation and deeper hole making capabilities. It is widely used in deep-hole drills and thread end mills.
