Hi experts. I was taking a 'heavy' pass through some mild steel earlier today and forgot that my vice is a bit undersized for my machine.... Seems newbie karma got me, the stock pulled out of my vice and decided to fling around a bit. In doing so smacking into my favorite, and only 1" Niagara HSS end mill that I was using for this pass.. It unfortunately put a decent sized chip in the one cutting corner of the two flutes. Please note, my heavy pass, is probably your finishing pass. I rarely use my mill to full potential and am quite scared of doing actual passes as I fear stuff like this happening, and I cherish my 'cheap' hss tooling because I have so little of it. Please see attached images. Is there any way I can repurpose the end mill? Or perhaps fix the chip? It is still useful for cutting but leaves a hideous finish. Maybe I'm just plain dumb, but I'll let the experts decide... P.S. I'm happy I decided not to go for carbide tooling as it probably would've come off a lot worse due to the brittle nature. I'm gonna swap back over to a more sizeable vice after this to prevent it from happening again. I mainly use this end mill for surface finishing so
Any useful advice or similar experiences would be appreciated.
I mainly use this for surface cuts, rarely using the sides so I really need a good cutting edge which the chip obviously has effected.
