Description

The ToolDocker Ball Nose Sintered Diamond Stone Bit is a long-life CNC carving tool engineered for 3D curved surface modeling, deep relief sculpting, rounded fluting, and organic contouring on hard granite, quartz, basalt, quartzite, and dense stone. Featuring a hot-pressed metal bond impregnated with industrial diamond crystals throughout the entire cutting profile, it delivers continuous cutting sharpness, extended service life, and smooth surface finishes across heavy production runs.

Key Features

Hot-Pressed Sintered Matrix: Solid diamond-metal bond continuously exposes fresh diamond crystals as it wears for maximum lifespan on abrasive stone.
Hemispherical Ball End: Engineered for smooth 3D contour milling, bas-relief sculpting, and curved surface blending with minimal tool marks.
Straight-Shank Rigidity ( $D = d$ ): Cylindrical body minimizes flex and machine chatter during heavy spindle loads on CNC stone routers.
Water Cooling Optimized: Built for wet milling setups to flush away slurry and keep temperatures low.
