Carbide V-Groove Router Bits

Carbide engraving bits for stone, marble, and granite | 10-mm cylindrical shank tools for CNC routers and CNC machines

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.

Two 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
