STRONGARM CARBIDE END MILL - 1/4" X 6"

Solid Carbide Mill-Drills

The perfect solution for drilling X-O locks! X-O locks require perfectly placed holes in the lock case when drilling for lost combinations.  Even trickier, the drill must not damage critical components located inside that case.

These exceptionally hard and sharp solid carbide Mill-Drills from StrongArm are ideal at doing just that.

Use them with your StrongArm Mini-Rig to penetrate into the case without drilling to deep. The cutting ends of the mills are very slightly tapered - giving the perfect mix of cutting ability plus depth control.
