Sintered Diamond Grinding Heads 6mm Shank Mounted Bits for Stone Lettering Engraving Carving Cutting Polishing

Heavy-Duty Sintered Diamond Grinding Heads (6mm Shank)

Manufactured using an advanced hot-press sintering process where high-grade industrial diamond abrasive is homogenously infused throughout the entire working matrix from core to surface. Unlike electroplated bits that strip once the surface layer is gone, these sintered points maintain aggressive cutting power and can be dressed repeatedly with a ceramic stone until completely worn down to the shank.

Technical Specifications

• Recommended Operating Speed: 6,000 – 23,000 RPM (Wet grinding with water cooling strongly recommended)
• Sanding & Grinding Applications: Stone lettering, 3D relief carving, edge chamfering, weld leveling, slotting, and precision deburring
• Suitable Materials: Granite, marble, quartz, bluestone, jade, technical ceramics, glass, and cemented tungsten carbide
• Tool Compatibility: Heavy-duty straight die grinders, CNC stone routing centers, rotary carving tools, and drill chucks with 6mm collets

Key Characteristics

• Solid Sintered Diamond Construction: Full-depth diamond impregnation guarantees extreme tool longevity and consistent cutting geometry throughout its operational life.
• Aggressive Stock Removal: Coarse P46 diamond grains provide rapid material evacuation without clogging or glazing under high load.
• Dressable Cutting Face: If the cutting surface becomes glazed during prolonged stone processing, it can be easily dressed and refreshed using an aluminum oxide or silicon carbide dressing wheel.
• Wet Grinding Optimized: Operating with continuous water flush substantially increases tool life, prevents thermal micro-cracking, and suppresses airborne stone dust.

Recommended Applications

• Monument & Stone Carving: Monumental lettering, decorative stone relief carving, countertop edging, and marble/granite sculpting.
• Ceramic & Glass Fabrication: Edge profiling, beveling, notch cutting, and hole chamfering on porcelain slabs and thick architectural glass.
• Toolroom & Metal Processing: Internal contouring, weld leveling, and deburring on cemented carbide dies and hardened alloy components.
