Destruction of the bolt that remained in the screw hole
5
From Japan
On 2014-03-31 14:19:34
I opened a hole to remove the stainless steel bolt with 6 holes that remained in the screw hole of the iron plate and could not be taken off. We gradually enlarged the hole so as not to damage the screw thread by using from a pack drill with a small diameter and finally removed the thin debris. Thought I was wondering what happens at one time, thanks to this drill pack I could punch a hole without any difficulties, and at the end I cut the taps and prepared the threads. Thank you very much.
