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.

Although we used to make a hole in fairly robust metal (material unknown), cut as I thought is was bad. I wonder if one is I have the bad ... the skill of the problem to can not be easily opened

Are you satisfied with the processing or the like of the difficult-to-cut materials.
It was processing Koguya's recommendation There is also flame-cut material with a trade (HRC ≒ 25 steel) in a Mitsubishi Materials Co., cobalt drill but was in trouble much if there is no match it.
Problem by using this drill was also smoothly can be processed without.
Since the blade length is long short shank than third-party drill feels like stiffness there.
Some people may even be evaluated as fragile, but in the place where I used to think that there is no problem.
