Drilling of flat bar of stainless steel
On 2015-06-16 15:30:41
As stated in the other person's writing, small diameter drilling of stainless steel is difficult. The precision of the drilling machine to be used · The cutting oil · the number of rotations will have a big influence. If you understand this it is a convincing product. I use it regularly.
S45c square hole piercing

Because the diameter is small, when I drilled with desktop milling machine keeping the rotation at 1000 rpn, the place near the edge of the blade rather than the cutting edge brilliantly broke and broke. Even though I did not move fast. It was at least a salvation that the cutting edge did not remain because the hole was not so much open. This manufacturer believes that COSPA is good and uses various sizes, but was it a third-tier manufacturer to crush using it for the first time? I guess it is useless unless it is a top manufacturer.

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

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.
