Used for slicing cherries and iroko, runs at high feed speeds, vibrates horribly. I slowed down the IPM and ran it faster, it worked for a few minutes then it started smoking and went dull for 10 minutes. You get what you pay for and save your money for it, I bought 4 and if you don't cut MDF just these are junk. I replaced Jerry's 2-shaft bit and cut 3 times faster and also cut 18 more boards perfectly.
