Carbide Tipped Die Drills are designed for drilling into 48-65 RC hardened steels, such as dies, bearing races, and safes. Often used as a reamer or core drill to produce close diameter holes. Tolerance +.000-.001

Solid Carbide Die Drills are designed for drilling shallow holes in 48-60 RC hardened steels, stainless steels, and high temperature alloys. Drills produce such accurate holes that extra reaming operations can usually be eliminated. Use rigid setups.
