Review on 🔩 Yonico 31014 SC 4" Diameter Spiral Router Bit by Orlando Mohr

I use these bits in my CNC router, primarily for cutting aluminum and plastic. Decided to use this bit instead of my Onsrud 63-610. The aluminum was T-65, which put more stress on the racquet than traditional non-tempered metals. Regardless, this punch lasted about 30 minutes in a 3 hour run. After it broke I switched to the onsrud bit and finished the job. While I don't think this bit is weak or ineffective, it does appear to be slightly weaker than Onsrud.
