Hi
I'm planning to make my own drill bit. I want a multiprofile one, I looked at the driggers but theyre quite useless, so going to have a go at making one from some threaded rod.
Anyone done this before and can give any tips? I plan to do the grinding with an angle grinder, diamond disc for bulk grind and an extra thin grit disc for the details. The M8 stuff is only mild steel, so I'm not sure how long the bit will last, but I expect it will manage 30 or 40 holes in softwood OK.
