Besly Modern Application Taps for Nickel Alloys

Besly Modern Application Taps for Nickel Alloys are for tough to machine Nickel Base Alloys such as Inconel, Hastelloy, Waspalloy, Incoloy, Astraloy, Rene and Monel. Designed for use in through holes, a spiral point is used to drive chips forward, reducing the chance of chip breakage.

These taps are surface treated to reduce friction and come with plug (3-5 thread) chamfers. The DIN lengths with ANSI shanks feature accommodates the sometimes needed extra reach without the need for special taps and set-ups.

Please call 800 435-2965 for current net pricing.
