Besly Modern Application Taps for Titanium Alloys

Besly Modern Application Taps for Titanium Alloys are for commercially pure Titanium and annealed Titanium alloys such as 6AL-4V. 

Designed for use in blind holes, a spiral flute is used to pull chips out, reducing the chance of tap breakage. Special back taper, thread and chamfer relief helps to reduce heat that commonly causes tap seizure and breakage on reversal.

These taps are surface treated to reduce friction. They come with bottom (1-2 thread) and modified bottom (2-4 thread) chamfers.

Please call 800 435-2965 for current net pricing.
