CNC V-groove router bits are commonly used in CNC routing to produce signage with lettering and other shallow detail. These router bits for lettering are best suited to create projects with an engraved design on a flat surface.
The v groove angle will determine how deep you can plunge for a given groove width. A narrower angle produces a deeper groove while a wider angle produces a shallower groove.
Some of the v-groove bits come with a flat bottom to enable you to engrave wide without going too deep.
