By the very nature of this 150 degree V groove router bit, your carves get done lightning fast because it has such a wide cut.

With a 1/4″ shank, it is the go-to v carving bit for home-based CNC’ers when it comes to larger projects. The ‘super-shear’ blade design is designed to leave exceptionally clean cuts at higher feed rates. This is the v bit to use when your v-carved letters are wider than 1″.
