Grooving for the insert coil to put in the blind hole

I bought the upper tap of M6 (AL - HT 1B STI M6 × 1 1.5P).
Because the attached tap of the recoil on hand is a middle tap, I purchased the upper tap for the blind hole. In the case of M6, the diameter of the recoil tap was about 7.2 mm, whereas the yamawa was about 7.35 mm, but the coil could be inserted without problems. Because the recoil coil diameter is slightly smaller, the attached taps are inevitably smaller somewhat. On the other hand, coils such as helisert are slightly larger, so it seems that Yamawa is also making it a little bigger. Either way I am satisfied that I could buy the upper tap at a reasonable price. I think I will buy another size if I need it.
