From Japan

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.

When the drilling about five places cutting edge is worn, sharpness is dull. I think that it corresponds to the price, but break it without, and it is a considerable number of drilling and re-sharpening, I was able to reach the objective.
