Centering, countersinking and V-slotting with a single tool. 

Thread milling in high hardness steels without pre-drilled hole.

The AT-2 thread mill with end-cutting edge for high hardness steels is ideal for highly difficult high hardness steel applications. The risk of sudden tool breakage can be minimized by breaking chips into small and manageable pieces and evacuating them smoothly. Since no pilot hole is required, process integration and the risk of breakage can be avoided.
