Much different and the thing that has been used until now, it has a sticky, some of the bend in the drilling can be processed without breaking cover the bend in the stickiness of the drill. It had surely broken the thing until now.
Perforation of thick stainless steel plate

Bite good. But, thick stainless steel be severe.
2.3t iron (SS400) was able to open without any problems. If the blade of φ6.8, bite even without pilot hole is good.
When drilling holes in the blade of φ6.8 and φ13 to SUS304 plate of 3t (pilot hole φ3.2, use a water-soluble cutting agent), it was opened while sharpening the cutting edge in the grinder so dull and opened one to two holes.
Stopped at the clamp to the SUS304 plate of 5t to two-ply (a total of 10mm thickness), and drill a hole of φ6.8 (pilot hole φ3.2, use a water-soluble cutting agent), the blade of the new may bite, It was a relatively short period of time can be 1 nail puncture, but will dull to be a second, now in a state where the cutting powder does not come out.
Looking at the cutting edge in the magnifying glass, also wear Ku outer periphery as well as the tip, had become like a cone Speaking drill blade is extremely. The wear of the outer peripheral portion is reached to 7 ~ 8mm in length direction, It is also hard to sharpen a grinder, also sharpening, it will not only open a few holes with a single blade. Again, stainless steel 10mm thick It seems necessary for carbide blade.
Use a stainless steel plate drilling and car of iron plate (for harder than normal iron pan).

It has been used for the development of specially equipped vehicles, but because they can be hard, especially frame portion, and the like.

It is the use of one-time Pokkiri but because there was a need to open sideways with a hand-held drill, I wanted to expire best.
A result, was able to fulfill without sharpness drops to last.
