6x60x0.1 Diamond Four Face Engraving Bit
A diamond four face engraving bit from JEEFOO in Guangzhou, China from JEEFOO in Guangzhou, China combines a 60-degree four-face profile with a fine 0.1 mm tip with a durable diamond edge for relief, lettering and dimensional carving. The 6 mm shank configuration provides four cutting faces and a 60-degree included angle so users can balance fine detail, reach and tool strength.
Suitable Materials and Applications
- Marble, granite and compatible engineered stone
- Tombstone lettering and decorative line work
- Ceramic and tile contour engraving
- Three-dimensional relief and sculpted surfaces
The 0.1 mm tip of this diamond four face engraving bit is intended for fine lettering and decorative outlines. A narrower angle can reach fine lines, while a broader profile is generally stronger and better suited to wider relief features. Cutting length must also match the actual depth without creating unnecessary overhang.
CNC Setup for Accurate Engraving
Confirm the shank fits the collet, clean both mating surfaces and measure runout before machining. Secure the stone blank on a rigid, level bed. Start with a shallow test pass, moderate feed and conservative step-down, then adjust according to spindle load, vibration, sound and surface finish.
A diamond four face engraving bit should move continuously through the material. Excessive dwell creates heat and can polish the surface instead of cutting efficiently. Use wet cooling when the machine permits it, or effective dust extraction for approved dry processes.
Improving Detail and Surface Quality
Use separate roughing and finishing toolpaths for complex relief. Leave a small, consistent finishing allowance after roughing, then apply a reduced step-over for the final pass. Stable fixturing and low runout help the diamond four face engraving bit reproduce fine lines without chatter marks.
Safety and Tool Care
Stone and ceramic dust can be hazardous. Follow machine instructions and use suitable eye, hearing and respiratory protection. Inspect the tool before each job and stop if diamond coverage is damaged, the shank is bent or cutting performance changes suddenly.
JEEFOO Tool Selection Support
When requesting a diamond four face engraving bit, provide the stone type, machine model, spindle interface, desired angle, cutting depth and finish requirement. JEEFOO can use this information to help confirm a practical DC-series configuration for production.
Frequently Asked Questions
Which angle should I choose? Narrow angles favor fine details; wider angles offer more strength and broader cuts. Match the angle to the artwork and depth.
Can one tool rough and finish? It is possible on light work, but separate roughing and finishing strategies normally improve tool life and surface quality.
