Carbide V-Groove Router Bits

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 bit cutting angles:

• 30° round-tip carbide router bits
• 30° flat-tip carbide router bits
• 45° V-groove router bit
• 60° V-groove router bit
• 90° V-groove router bit
• 15 mm diam – 90° V-groove router bit
• 105° V-groove router bit
• 120° V-groove router bit

Recommendation:
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

Typical parameters:
Plunge (step in Z): 1mm
Spindle speed: 7000 rpm
Feed rate: 400 mm/min
Plunge rate: 80 mm/min with ramp maneuvers
Material: marble

Note:
You will need ER-Collet sized for 1omm fittings when using a 10-mm shank tools
