Review on 🔪 Amana Tool 46225 K Spektra Down Cut Router Bit by Ronald Dimatulac

I cut 1/4" Baltic birch plywood with $5 Chinese compression drill bits with no problems. Thought I'd give this beat a try. Tried to do the same with this beat ( bought twice) and it broke after cutting only 4. I'm just sticking with the $5.00 beats as I don't want to pay $36.00 for another disaster and wrecked work.
