Cutting Taps Basic Knowledge

I'm thinking of regrinding taps to reuse them. Are there any recommendations that define which types of taps can be resharpened and which ones can not?

The performance of all taps is highly dependent on the balance of elements like, the cutting angle,
the cutting chamfer and the margin width.
Normally, Yamawa does not recommend regrinding taps because it will result in a loss of
performance of the resharpened taps compared to the originally factory ground taps.
If you do decide to resharpen taps please refer to the following points when regrinding them.
