Thread: Carbide CNC bits cutting life?
Threaded View

Hi.
I am cutting furniture out of 12mm MDF using Straight 6mm 2 flute carbide bits.
I usually take 4 passes (3mm each). The bits last on average about 80 mins before sounding 'wrong' and emitting burning smell.
Is this about right? or should they last longer. I have tried various ones from UK and from China, but they are all about the same.
Just wanted to know if this sounded normal, or wildly out.
