Very happy with how smooth these bits are. I'm making some recessed panels to cover the four pillars in the entryway. I used the 1/8" setting to test, then switched to the 1/4" setting to complete the cutout for the panels. 4 without question. From now on I will look for CMT bits whenever I need to change something or get a new profile. It is great. You will not regret this purchase. worth your money.
