Drilling of sus304, sus 316L

Sus304 can be used with confidence. Cospa is nice. Sus 316L has poor blade holding. The defect of the blade leads to defective products, so if the cospa is good, I would like a good one to hold. Especially in products which are hardened by the plasma of thick material, the blade holding is particularly bad.

Drill hole processing of difficult tap material tap with MC.

You can cut well. Since it is an obtuse angle, there is a designation of the depth of the pilot hole of the tap by MC, and it is convenient to secure the pilot hole of the tap when it drives the tap with just the edge.

Sharpness is good. Unlike made in China, there is no warp. I think that accuracy is also good. I will also buy it.
