About tap regrinding Vol.1

【英】困ったときの知恵袋詳細
Cutting Taps Basic Knowledge
I would like to continue using my worn taps by resharpening them. Can you tell me the critical points I have to keep in mind when regrinding my used taps.
The cutting performance and stability of a tap is dependent on a balance of several elements
such as the cutting angle, the chamfer relief and the margin width. It is difficult to resharpen
a standard tap that was designed to run at high speeds. It is even more difficult to recreate
the grind and produce the same cutting performance of a special tap that was developed for a
specific industry. You need to be very careful when regrinding taps as any type of tap
regrinding may cause problems with duplicating the original performance of the tap.
