Up on the cnc roof I heard a chatter, and when I looked I was blinded by a super red glow!!! And with a puff of smoke my bit was toast !! Hahahaha
I had set my cnc to run at 200ipm and a depth cut of .005”. Needless to say the first bit snapped. So I slowed the feed to 60ipm and got a lot of it cut until that bit wore out. Same with second bit but it went faster due to the fact that the wd40 started soaking into the mdf that I spray glued the sheet toand swelled up causing the bit to dig in to deep.
I don’t think the bits I have can take a single pass cut.
