I’m having trouble drilling holes – the bit gets very hot quickly and and starts to burn the wood.
I’m using the “drill” operation in Estlcam, so it makes multiple passes. I’ve tried different speeds on the router (Makita running at full speed, then 6 then 5 on the dial). The Z speed is 3mm/second and I’m drilling 3/4" pine to full depth.
It strikes me that the bit I’m using might not be appropriate - its a 1/4" 2 flute downcut. Would the downcut be packing the chips in and causing the heating?
