The demands for tapping into heat resistant alloys and stainless steels are increasing rapidly in the Aerospace Industry. The most common heat resistant alloys are Nickel base alloys, such as A286, Inconel, Hastelloy, Waspaloy, and Titanium alloys. There are considerable difficulties in tapping these materials due to their material features which can easily cause severe damage to taps.
YAMAWA has the best line of taps for such a severe tapping conditions.
