Drilling into stainless steel bolt (SUS 430)
On 2014-10-30 23:51:57
I usually handle only wrought copper material and I was drilling for stainless steel bolt (M14 SUS 430) for the first time, but it was crisply opened with no problems. I only drilled four holes at the most, so I will not mention durability, but I was able to accomplish the intended work properly.
Used to drill holes in resin.

It was saved because I received it immediately. The feeling of use was also no particular problem.
