Our multi‑layer cladding granite relief carving bit is a professional cutter dedicated for CNC stone relief work. Also known as granite “God‑knife”, this metallurgical fused diamond tool is widely used for engraving granite, marble, bluestone, sandstone, yellow rust stone, golden hemp stone, foam ceramic and tombstone relief patterns.
It combines the sharp cutting performance of electroplated diamond bits and the wear‑resistant durability of sintered stone cutters. One bit achieves two‑tool performance, greatly improving your stone processing efficiency.
Core Features
✅ Multi‑Layer Cladding Diamond Grain Tip
Adopt metallurgical fused diamond abrasive grain. Higher wear‑resistance, longer service life and better durability. Excellent sharpness and consistent geometric precision for carving tips.
✅ Advanced Fusion & Cladding Craftsmanship
High‑strength bit body, low deformation under heavy‑load carving. Run at higher feed rate for boosted production efficiency.
✅ Thickened Anti‑Break Round Shank
Upgraded thick round shank structure, effectively prevent tool break‑off during heavy‑depth stone engraving. Safe and stable for long‑time CNC operation.
✅ Wide Material Compatibility
Perfect for relief carving: Granite, Marble, Bluestone, Sandstone, Golden‑Grain Granite, Yellow‑Rust Stone, Foam Ceramic, Tombstone stone materials. Fast carving speed with exquisite relief output.

Tool Selection Guide
- Shank Diameter: Choose shank size based on carving depth & machine rigidity. For relief depth within 20 mm: 8 mm shank is preferred. For relief depth over 20 mm: select 10 mm or larger shank. High‑speed working condition recommends larger‑diameter shank for better rigidity.
- Tip Size: Pick the largest possible tip diameter that meets your detail precision requirement. Larger tip brings longer service life. For example, use 6 mm tip instead of 3 mm / 4 mm if precision allows.
- Cutting Length: Select cutting length with proper margin over your carving depth. Example: For carving depth 26 mm, choose 30 mm cutting‑length bit; for 15 mm carving depth, choose 20 mm cutting‑length bit, avoid grinding shank accidentally.
Note: Suitable for relief engraving work for soft‑medium hardness stone. Not for heavy deep slotting.
