Made in USA since 1992

Which material is right for your job?

Carbide - Long Length
Carbide - Long Length
Carbide
Carbide Stiffest — resists point wander Wants a rigid setup Best for Production centering, harder material
Cobalt
Cobalt M42 — holds hardness under heat Tougher than carbide under load Best for Stainless and tough alloys, sizes 1 to 4
HSS
HSS Widest size range, 00000 to 8 Regular and long length Best for General lathe work and hole starting

Combined drill and countersink tools, also known as center drills, are used to create an accurate starting point and countersunk center for lathe work or precision hole starting ahead of a full-size drill. We stock these in Carbide, Cobalt, and HSS, with HSS available in both Regular Length and Long Length.

A clean, accurately placed center drill point prevents drill wander on the next operation, which matters most on tight-tolerance or deep-hole work. All combined drill and countersink tools are manufactured in the USA and stocked for same-day shipping.
