Taper Vacuum Brazed Diamond Stone Bit – CNC Router Carving Tool for Granite & Marble

The ToolDocker Taper Vacuum Brazed Stone Bit is designed for stone fabricators, memorial sculptors, and architectural CNC operators. Unlike standard electroplated tools that wear down quickly or sintered bits that require continuous dressing, vacuum brazing chemically fuses sharp diamond grit directly onto the steel body. This results in exposed cutting edges that slice aggressively through abrasive stone surfaces without premature dulling.

The tapered profile balances structural core stiffness at the base with a fine tip radius (1 mm to 8 mm), enabling deep contouring (L1 cutting lengths from 6 mm up to 100 mm) while reducing machine deflection and tool breakage.

Key Features

• Vacuum Brazed Diamond Technology: Industrial-grade diamond particles are metallurgically bonded using high-temperature vacuum brazing to prevent segment stripping and ensure maximum retention.

• Clean Detail & High Precision: Tapered tip geometry allows sharp internal cornering, fine lettering, and smooth curved relief without chipping brittle stone surfaces.

• Broad Stone Compatibility: Effective for engraving and milling marble, granite, quartz, terrazzo, limestone, sandstone, jade, and architectural ceramics.

• Universal CNC Shank Compatibility: Standardized round shanks ($6\text{ mm}$, $8\text{ mm}$, $10\text{ mm}$, and $12\text{ mm}$) fit industry-standard ER collets (ER11, ER16, ER20, ER25, ER32) across standard CNC stone routers and heavy-duty spindles.

• Wet & Coolant Cutting: Optimized for wet milling setups to flush away stone slurry, minimize heat buildup, and preserve cutting edge geometry.
