Alright so sorry to any machinists I may disappoint here with my ignorance. Anyhow today I was working on two knives I have for some customers and on the blade portion there is a 7/8 in diameter finger hole. My problem is I was drilling the hole with a typical (Milwaukee) step drill bit that is new and when I got to 5/8in hole the bit just stopped cutting. Like when I mean it stopped the bit does not go a millimeter more further. I’ve tried all I know at the time to resolve the issue. So far I’ve attempted to anneal it, change drill press RPMs, and yes I am using lubricant to keep the heat down. This is a stock removal project so it should be soft. The steel is from New Jersey Steel Baron and I know it’s good stuff but it’s giving me a hell of a time. I thought about buying a carbide tipped masonry but because the seems to help a few people. But right now I’m pretty stuck, anyone have any ideas? I would be more than happy to take any advice I can get.
