  Besly Modern Application Taps for Stainless Steel

Besly Modern Application Taps for Stainless Steel are for tough to machine Stainless Steel Alloys and Precipitation Hardening (PH) Stainless Steels. Designed for use in blind holes, a spiral flute is used to pull the chips out of the holes, reducing the chance of torn or rough threads.

These taps are surface treated to reduce loading and galling. They are available  with bottom (1-2 thread) or modified-bottom (2-4 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.

Note: Click the EDP No to check availability.

   
All dimensions are in inches.
