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 through holes, the spiral point propels chips ahead of the tap, reducing the chances of torn or rough threads.

They are surface treated to reduce loading and galling and come with plug (3-5 thread) chamfer. 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.
