Amastone’s solid carbide engraving router bits are ideal tools for engraving and lettering stone and for finishing and bas-relief work in general.
These made-in-Italy high-quality stone engraving bits for marble. Widia – solid carbide – engraving bits with a cutting angle adge of 30°, 45°, 60°, 70°, or 90°. They may have a rounded tip (0.5 mm radius) too.
The bit shank is 10mm in diameter and bored for the inner water flow.
The 60° and 90° tips also come with a reverse cutting edge to be used on machines with an anticlockwise rotation.
When using a single lip carbide bit, we recommend the following parameters for your CAD/CAM program
- Speed of rotation 5000 to 7000 RMP as a function of feed rate
- Feed rate between 100 and 500 mm/min based on depth in Z and material hardness
- Maximum depth 3mm (recommended 1mm)
- Ramped plunge recommended for stone
