AT-2 Vol.3

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.

Thread milling cutters series VOL 6

Thread mills are tools designed to cut threads by milling. Thread mills are used on numerically controlled machining centers (NC) that have simultaneous, triaxle control and helical interpolation functions. In comparison to general tapping, thread milling is more stable with less cutting condition limitations in terms of chip management and coolant lubricity. Discover our line-up of thread mills inside the brochure.
