Funny I was just looking thru a tool catalog today enmll shopping. Marveling at how gawd awful expensive they get especially the 1"ers!! Sorry bout that. Might be worth it to sent to a sharpener they can shorten it 3/8" and regrind. Might be $50 to save a $200+ endmill assume its carbide.
I bet that Gorton mill didn't miss a beat and kept on ticking!
I did the same thing on a 3/4" endmill in one of the Gortons we used to own several years ago. Bad thing was I did it twice on the same setup back to back. Yeah, it sounds like three shot guns going off at the same time.
Sorry for it being so long to get back. How it happened was a gorgon mill has gear driven power feeds, I engaged the feed the wrong direction and before I realized what I had done it caught a 1 inch raised area of the piece I was milling.
Since it was going the wrong direction it was climb milling and didn't like the feed rate.
The it'll buff out comment brings back a lot of memories, I delivered new vehicles for over 20 yrs.
Thanks scruffy ron
