Carbide engraving bits for stone, marble, and granite
Carbide engraving bit for CNC routers and CNC machines for 10-mm cylindrical shank tools
This is the most widely used (and our most widely sold) carbide tip used by stoneworkers who write, engrave, and finish marble and granite, including bas-relief creations with CNC machines and routers.
2 different versions are available: M, for marble, and G, for granite. Choose the correct carbide alloy for your application. Versions with or without through-tool-cooling are also available. Bore-holed bits allow water to pass within the tool to cool it.

Carbide tips are recommended especially for marble and soft stone. To engrave hard granite and particularly abrasive materials, we recommend PCD, polycrystalline diamond-tipped tools for granite.
Recommended operating parameters
We recommended the following parameters for your CAD/CAM program when using single-lip bits.
- Spindle speed between 5000 a 7000 RPM as a function of the feed rate
- Feed rate between 100 and 500 mm/min as a function of the plunge Z and material hardness
- Maximum depth 3 mm (recommended 1mm)
- We recommend ramp maneuvering when penetrating the stone
Plunge (step in Z): 1mm
Spindle speed: 7000 rpm
Feed rate: 400 mm/min
Plunge rate: 80 mm/min with ramp maneuvers
You will need ER-Collet sized for 1omm fittings when using a 10-mm shank tools
