I’m cutting 60x35” oval countertops out of 1” MDF that has bee laminated with melamine.
Using a 1/2” straight plunge 2 flute and did these 3 tests at the feeds and speeds shown. Bit was hot after tests 1 & 2, not so much on #3.
Cuts quiet, with nice smooth edges and no chipping.
My question is how to get rid of the burn marks shown at the plunge point?
