Our CNC diamond carving bit is built for stone engraving, lettering, and shallow relief work on granite, marble, and quartz. It helps shops cut clean lines and logos on countertops, monuments, signage, and architectural panels. High-grade diamonds and a stable cutting feel keep the tool tracking smoothly on tight paths, reducing edge chipping and rough groove walls. You get sharper detail, less rework, and steadier results in both custom jobs and batch runs.

The DINOSAW CNC diamond carving bit is the engraving-tool family for the ZDDK platform: seven diameters from Φ6 to Φ20 mm cut monument lettering, decorative grooves and relief programs in stone — with working heights to 150 mm and round-shank mounting for direct CNC spindle fit.

Real Engraving Performance & Key Metrics

Seven Diameters

Seven diameters cover the engraving spectrum: fine bits for lettering and detail, large bits for relief roughing and background removal.

Working Height Range

Working heights from 6 to 150 mm serve shallow etching through deep relief programs — with machining depth achieved by programmed step-down passes.

Direct Collet Fit

Ø6–20 mm round shanks mount directly in standard CNC collets: concentric grip without adapters, protecting the fine-detail accuracy engraving demands.

Diameter Progression

Larger diameters remove relief backgrounds efficiently; smaller diameters follow narrow strokes, lettering corners and fine decorative details: complex programs typically move through a diameter sequence rather than asking one bit to do every stage.

Working-Height Range

Working heights extend to 150 mm for deep-relief tool access — with actual machining depth achieved through programmed step-down passes per material and bit diameter, not a single 150 mm plunge.

Diamond Cutting Edge

Diamond tooling is better suited than conventional carbide to abrasive stone and sintered materials, maintaining a sharp cutting interface longer through engraving programs — edge life is the difference on production lettering runs.

Complete Production Solutions & Equipments

Choose equipment combinations for your product needs to establish efficient automated production lines and maximize profitability.

Built for flat engraving, relief carving, and 3D work. Pairing the machine with a diamond carving bit improves depth repeatability and corner control on lettering, logos, and decorative patterns.

Use for routing outlines, trimming, and shaping before fine engraving. Router bits handle heavier stock removal, while carving bits focus on crisp lettering and clean etched walls—better workflow, less tool stress.

After engraving, polishing pads refine groove edges and surrounding surfaces to remove fine scratches and restore gloss. Useful for marble decorative lines, quartz logos, and sintered slab detailing where “finish quality” sells.
