Drilling of stainless steel flat bar
From Japan
On 2015-06-16 15:30:41
Small-diameter drilling as stainless steel writing of other people is difficult. Will precision, cutting oil, the number of revolutions of the drilling machine to be used has been greatly affected. Once you understand this is a convincing product. And love.

Drilled under hole in the S45c angle bar
From Japan

Since the diameter is small After drilling to keep the rotation in a tabletop milling machine to 1000rpn, beautifully broken is a place close to the blade source rather than a cutting edge, it broke. It will be not how to proceed was faster. Since the hole was not open so, the cutting edge was left was the salvation of even at the very least. The manufacturers believe that is good COSPA, has been using a variety of size, or would do was a third-rate manufacturers and crumble with the first time. I guess useless and thin the is not a first-class manufacturer.

Work to widen the pierced hole

It is natural that 1 mm used by me is thin, but as soon as the sharpness of the tip got worse it broke.

Drilling in stainless steel pipe (wall thickness 1 mm)
From Japan
On 2012-07-16 13:37:26
When drilling about five places, the cutting edge wears and the sharpness becomes dull. I think that it is suitable for the price, but it did not break, and when sharpening again a considerable number of holes could be made and the purpose could be reached.
