Drilling for cap bolts

It is easy. However, I often use SUS 316 L, so I do not have much. I want a little more durability with coating etc.

It is suitable for counterbore processing. You can cut well.

I thought that the diameter of the shank was thicker than I thought so that I could grasp it with a drilling machine? Well it's about 10 mm, but I think that this is for M6 with hole diameter 10 mm bolt 6 mm and then for M5, M4, M3, M2.5.

It is very satisfying with the product. It is 100 points, and I'm happy that it is already two or three centimeters long. * I am requesting from here, I knew that this product was from before but there is a doubt in the photographing of the product and I bought a Fukuda Seiko (FKD) for a submerged milling cutter with a drill (for a hexagon socket head bolt) However, (Fukuda Industry is short in length), I bought a chamfered drill TPT for cap bolt (tip of a halfway shaft), I wanted consumers to understand a little more about the angle of photography and so on. The image for M8 had a look like the boundary of the cap from the drill as thin as the bowling pin so it felt like I felt like it for a flat head screwdriver but I bought it for purchasing, It was for the cap bolt, I am very sorry to purchase two similar things before,

I got broken when it ceased to run. It is cheap, so I will buy it again.
