Carbide edge-rounding bit for Marble
This tool is used to round and fine-finish the edges of engraved cuts in marble, limestone or other natural stone. These edge rounding bits come with 3 different internal radiuses (2.7 mm/3mm/4 mm) and come with a bored or non-bored version (depending on whether through-tool cooling is desired).
This tool is not used just to finish engraved edges but is often used to fine-finish the edges of relief lettering on stone signs, emblems, tombstones, etc. using a swift manufacturing strategy involving, as a first step, the rough-cutting of a base, leaving the desired lettering in relief, followed by the fine finishing of the lettering contour with this bit).

- Spindle speed: 5000 – 7000 rpm, depending on feed rate
- Feed rate 100 .500 mm per minute based on plunge and material hardness
- Maximum plunge: depending on bit radius
