My pa bought this machine anbout 2014, for a contract needed ann AWD grader, and it’s had a gob of issues keeping the cutting edge bolts tight. They are 5/8 bolts and there’s every other hole drilled. So I got it in the shop and started poking holes. I got a box full of bits and even some that I have sharpened myself for hard steel. (Down to about a 110° point. The first 3-4 holes went well and now I think I have run into work hardening ? Can’t penetrate it with a common bit, or a 110° to just make a pilot hole. I tried putting torch to it - but I poured water on it and I’m thinking that was wrong now.
