Review on 🔩 Yonico 31014 SC 4" Diameter Spiral Router Bit by Luis Thompson

I bought these as a cheaper alternative to the Onsrud and Amana O-Flute series. They totally did the job and very good value for money. Their bottom edge in the pockets is the only area they brand. They have excellent chip control and clearance in plastics as well as good surface finish. I use them in lots of HDPE and Acetal with a desktop CNC router (Axiom AR1). These bits run easily at 60-100 ipm on such a small machine and still deliver a good cut.
