That depends on the detail, material, and groove shape: narrow angles create fine, narrow cuts, while wider angles can make wider grooves and are suited for different lettering styles. Some examples include 30°, 60°, and 90° V-tip inserts, for useful flexibility rather than one universally best angle. The RCK-360 30° insert suits fine-line engraving, while the RCK-380 60° insert provides a wider-angle option and I use them both in my shop for a quality cut. The RCK-392 90° insert expands the choices for broader V-grooves; several angles are available to match your work. There is a no option in my shop but to buy the Amana Tools bits and blades.
