Drilling in stainless steel

Compared with ordinary blades, machining can be performed with the same precision without a center drill. Also, since it bite well and cut very well, it became possible to raise the feed speed more than before. On our side, if we skipped the center drilling process, we could shorten the working time to nearly one - third of the previous one, and it was possible to greatly improve working efficiency.
