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 through holes, the spiral point drives the chips forward. Special relief, point diameter, spiral point and chamfer geometry helps reduce heat that commonly causes tap seizure and breakage on reversal.

These taps are surface treated to reduce friction and come with plug (3-5 thread) chamfers.

Please call 800 435-2965 for current net pricing.
