The “Straight 4” 1/4″ solid carbide ball-nose endmill CNC router bit is the bit to use when you want to soften down those features that look too sharp on your projects
The 1/4″ ball nose adds that missing delicate rounding effect to your signs and raised lettering when something seems a bit too ‘hard’ with your project.
As with all CNC router bits on this site, the Straight 4 1/4″ ball-nose endmill bit is made right & built to last. That’s why these are made above industry standards and 100% tungsten carbide.
Carbide is what professional metal machinists use to make complex items like car engines. It stays sharp 50x longer than conventional CNC router bits.
