I understand dust vs chips, and I think I make proper chips?
I usually start makita at 1 and go up if router is struggling. Or, like with hardwoods, I start around 2 - just in case, and then slow down. I don’t know if it’s good or not, but whenever I measure temperature of the bit, it’s in 20s C… but I still made endmill completely dull while cutting out just two trays from hardwood ( Christmas gifts! Trays! ). I buy only cheap bits for now, cos I expect them to live short, but not that short, tbh?
Can anyone tell me how many hours of milling cheap/expensive bit should last?
