die drill - side and front view
Die Drills are designed for drilling into 48-65 RC hardened steels. They produce very accurate holes and can be used as a reamer.
Die Drills - Carbide Tipped
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

Die Drills - Solid Carbide
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.
