Solid carbide engraving bits for CNC routers and machines – Amastone
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 solid carbide engraving bits have a lip angle of 30°, 45°, 60°, 70°, or 90° and may have a rounded tip (0.5 mm radius).
The 60° and 90° tips also come with a left lip (or cutting edge).
The bit shanks are 10mm long and bored for the passage of water.
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 55 mm/min based on depth in Z and material hardness
- Maximum depth 3mm (recommended 1mm)
- Ramped plunge recommended for stone
