Review on 🔪 Precision and Durability: CMT 191 001 11 Carbide Spiral Diameter for Enhanced Cutting Performance by Jeff Drollinger

I used this bit on my usual expensive aluminum router with CNC in a pinch. I originally bought this bit to cut MDF, but when I was in the middle of a job and the other one broke, I installed it in my router and expected it to break within minutes. I turned some parts out of 6061-t6 aluminum and it turned out great. I just ordered another one and will continue to test it cutting aluminum. I hope they hold up well enough to give up my more expensive bits.
