Description

The ToolDocker Ball Nose Vacuum Brazed Stone Bit is an industrial diamond CNC router tool designed for 3D curved surface modeling, round-bottom slotting, bas-relief sculpting, and drainage groove fluting on granite, marble, quartz, and architectural ceramics. Its rounded tip provides seamless step-over blending between toolpaths, drastically reducing post-carving polishing time.

Key Features

  • Hemispherical Ball Nose End: Engineered for smooth 3D contour milling, decorative fluting, and organic curved relief carving on hard stone.

  • High-Density Vacuum Brazed Diamond: Industrial diamond grit chemically fused to the steel core for fast feed rates and extended wear resistance.

  • Standard Industrial Shanks: 6mm, 8mm, 10mm and 12mm shanks fit standard CNC ER collet chucks.

  • Wet Cooling Optimization: Built for active water-flood stone CNC routers to clear abrasive slurry efficiently.
