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 blind holes, a spiral flute is used to pull the chips out, reducing the chance of tap breakage.

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

Please call 800 435-2965 for current net pricing.
