I just got in a couple VERY nice endmills from Maritool. They are 3 flute 45 degree helix roughing endmills. I put this 3/8" endmill in my X3 and did a 0.125" depth slot going 12IPM at 2000RPM. It seemed to work very well with no vibration, just a nice clean slot. When I removed the endmill I saw that the edge of one of the flutes was chipped. Bummer, this endmill only had about 1 minute of cutting time.

That was my first cut. I swapped out the endmill with the 2nd one I ordered of the same type and went on to do an hour of cutting with zero issues and that endmill cut through the aluminum like butter.... VERY nice.


My question is, did I get a bad endmill? Can this one still be salvaged, it's a ~$30.00 tool, and I'd like to get more than 1 minute of life out of it.
