Straightness at best may last longer than the drill of high-speed steel

Kobelco of the drill that was favored 10 years is no longer cut, I bought here review was good. But sharpness is doubtful from around to open the three-hole, fourth hole, the 5 hole eyes I have become almost equivalent cut name as the 10-year use Kobelco. Do it because foreign-made (made in Singapore)? It is the worst. I will no longer buy.

Reaming of pilot holes

We are satisfied with processing of difficult-to-cut materials etc. There was a recommendation of a tool shop with dealings, and I was processing difficult-to-cut materials (HRC ≒ 25 steel) with a cobalt drill made by Mitsubishi Materials, but I was in trouble because my teeth were inconspicuous. By using this drill, we could finish machining without problem. I feel that there is also rigidity because the blade length is shorter than the other company's drill and the shank part is long. There are also people who evaluate it as easy to break, but I think that there is no problem in the place I used it.
