Cutting MDF for T-slot

Postby Casper » Sun Apr 03, 2016 5:59 am

A 6mm bit that I am using to cut some MDF 30mm thick for T-slot spoiled board has got burnt. It was running at 850mm/min. I want to buy some 2 flute HSS bits, 2 flute carbide and straight flute bits.
Was this setting too slow or high for cutting the MDF?
Also, which of the 3 different cutters that I want to buy is good for my job?

HSS will wear out so fast. So do not waste your money buying it.

The straight flute will work well if you have a good vacuum. Spiral up cut would work better. They remove chips much better than any

What is the main function of the vacuum for the straight flute?

The vacuum is for dust collection. You don’t need it for blowing or sucking for now especially if you can clear the chips.
