3×15 Brazed Diamond Stone Carving Bit Guide
The 3×15 Brazed Diamond Stone Carving Bit is a precision tool for detailed engraving, narrow channels and controlled material removal in granite, marble, ceramic, engineered stone and other compatible mineral materials. Its 3 mm working diameter reaches fine features, while the 15 mm diamond working section supports deeper relief than a short point tool.
Brazed diamond construction
Vacuum-brazed construction exposes a strong layer of diamond abrasive and bonds it securely to the metal body. This open surface helps the tool cut efficiently and release stone particles when cooling and dust control are suitable. The geometry is intended for carving and finishing; it is not a substitute for a large-diameter roughing tool when heavy stock must be removed quickly.
Key specifications
- Working diameter: 3 mm
- Diamond working length: 15 mm
- Tool type: brazed diamond stone carving bit
- Typical materials: granite, marble, ceramic and engineered stone
- Typical work: fine grooves, lettering, relief and narrow contours
CNC setup and machining advice
Before machining, confirm that the shank matches the collet and that the spindle, holder and workpiece are secure. Keep tool overhang as short as the feature allows. Set the tool above the surface, verify the programmed path and begin with a conservative feed rate and shallow depth per pass. Increase engagement only after checking spindle load, vibration, sound and the quality of the carved surface.
Stone dust is hazardous and abrasive. Use the machine manufacturer’s approved wet-cooling or dust-extraction method, appropriate guarding and personal protective equipment. Water cooling can help control heat and dust when the machine and electrical system are designed for wet processing. Never introduce liquid to equipment that is not rated for it.
How to improve tool life
- Avoid forcing the 3 mm tool into deep full-width cuts.
- Use several controlled passes for deep relief or channels.
- Maintain consistent cooling and remove abrasive slurry.
- Inspect the brazed surface and stop if the body bends or the bond is damaged.
