6x30x0.2 PCD Engraving Bit Guide
A 6x30x0.2 PCD engraving bit combines a 6 mm shank, 30-degree cutting angle and 0.2 mm flat tip for fine CNC lettering and narrow decorative grooves. The flat bottom creates a consistent groove base and provides more tip support than a sharp point. Polycrystalline diamond offers high wear resistance when the tool is matched to a suitable abrasive material and machining process.
Applications and Material Compatibility
The cutter can be considered for fine characters, logos, line work and controlled-depth engraving. Depending on the exact PCD grade and tool design, applications may include approved non-ferrous, composite or hard decorative materials. Ceramic, tile, marble or stone use should be confirmed with the supplier because material structure and machine conditions vary.
- Fine CNC lettering and logo engraving
- Narrow decorative grooves with a flat base
- Controlled-depth marking in approved abrasive materials
- Repeat-production engraving after parameter validation
Understanding the 6x30x0.2 Specification
The 6 mm value identifies the shank, the 30-degree value identifies the included cutting angle, and 0.2 mm identifies the flat tip width. Confirm the complete drawing, overall length and usable cutting geometry before programming. Engraving width changes with depth because of the angled profile.
Calculate the required depth from the target groove width and confirm it with a test cut. Do not rely on the nominal tip width alone. Machine runout, material flatness and tool-setting error can noticeably affect fine engraving.
CNC Setup and Cutting Control
Clean the collet, verify low spindle runout and clamp enough of the 6 mm shank for stable rotation. Secure and level the workpiece so the programmed depth remains consistent. Begin with a shallow test pass, conservative feed and material-appropriate spindle speed.
Inspect the groove base, line width, chips or dust, cutting sound and tool loading. Use suitable extraction, cooling or lubrication only when approved for the material and machine. Avoid impact, excessive plunge load and sudden side engagement because PCD cutting edges can be damaged by improper handling.
JEEFOO PCD Tools from Guangzhou, China
JEEFOO supplies precision CNC engraving tools from Guangzhou, China for distributors, manufacturers and workshop users. Share the material, desired groove width, depth, machine type and production volume when requesting a 6x30x0.2 PCD engraving bit. Explore more tooling information on the JEEFOO cutting tools website.
For general information on PCD as a cutting-tool material, see the reference on polycrystalline diamond. Record verified tool length, depth, feed, speed and cooling method with the CNC program for consistent repeat work.
Production and Inspection Checks
Make a short test engraving in the actual material before full production. Measure line width and depth, inspect the flat base and check for edge chipping or surface damage. Confirm that the tool returns to the same zero reference across the work area. Store the approved sample and parameter record with the job.
Frequently Asked Questions
What does the 0.2 mm value mean?
It identifies the nominal flat tip width. Actual groove width also depends on engraving depth, runout and the 30-degree cutting geometry.
Can this bit engrave every stone or composite?
No. Confirm material compatibility, tool grade and cutting method with the supplier before use. Different materials require different parameters and may need specialized cooling.
How can engraving consistency be improved?
Use low runout, a level workpiece, accurate tool-length setting and shallow validated passes. Maintain the same zero reference and inspect the 6x30x0.2 PCD engraving bit before each batch.
Product Description
This PCD flat bottom engraving bit uses a 6 mm shank, 30° cutting angle and 0.2 mm flat tip for fine, narrow engraving. The sharp low-angle profile supports detailed characters and delicate decorative lines, while the flat bottom improves tip durability and gives the groove a consistent base.
Polycrystalline diamond provides high wear resistance for extended production on suitable abrasive non-ferrous, composite and hard decorative materials. The cutter is intended for precision CNC engraving with controlled depth. Stable workholding, low runout and gradual passes help maintain edge quality and repeatability.
Recommended Applications
- Ceramic, tile, marble and compatible stone engraving
- CNC lettering, logos and decorative groove carving
- Precision machining with controlled depth and stable workholding
