- Product Name: Granite Relief Carving Bit
- Cutting‑edge Technology: Granite relief carving bit
- Tip Shape: Conical Ball Tip
- Application: Specially developed for granite relief carving. Provides fast engraving speed and excellent carving performance.
Main Features
01 Imported Diamond Grit
Tip thickness: 8 mm. Higher wear resistance, longer service life and enhanced durability for stone‑carving workloads.
02 Dual‑Performance Design
Combines the sharp cutting performance of brazed bits and the high durability performance of sintered bits. One bit achieves two‑fold working effect for higher practicality.
Product Details
- Anti‑tip‑off, 4‑layer grit on side face Manufactured from premium high‑speed tool shank raw material. Anti‑breakage performance for smooth stone relief carving operations.
- Distinct grit particles for sharp cutting edges Low operating noise during engraving, improved wear resistance and sharp cutting performance.
- Thickened Reinforced Shank Upgraded thickened shank construction effectively prevents tool shank fracture for secure operation.
Application Scope
Specially designed for relief carving process, perfect working tool for granite material. Suitable for CNC stone engraving machine processing on granite, blind‑path stone, tombstone engraving jobs.
Tool Selection Guidelines
- Application Range Fused diamond relief carving bits apply for relief work on marble, bluestone, sandstone, granite and similar stone materials, featuring fast engraving speed and good carving results.
- Tool Geometry Selection Three key dimension parameters: shank diameter, tip size, cutting‑flute length. Example mark: 12‑6‑100 means 12 mm shank diameter, 6 mm tip diameter, 100 mm cutting‑flute length.
- Shank Diameter Selection Select proper shank diameter for sufficient tool rigidity to avoid tool breakage. Required shank rigidity varies according to stone hardness, carving depth, feed speed, CNC machine rigidity and spindle perpendicularity. General suggestion: For granite relief carving, use shank diameter ≥ 8 mm. ‑ Relief depth ≤20 mm: 8 mm shank is preferred ‑ Relief depth＞20 mm: choose 10 mm shank ‑ For high‑speed capable CNC machines, select larger‑diameter shanks for high‑speed processing.
- Tip Diameter Selection Under premise of meeting carving precision requirement, choose the largest feasible tip size. Larger tip extends service life. Example: If 6 mm tip meets precision demand, avoid 3 mm /4 mm smaller‑tip versions.
- Cutting‑flute Length Selection Set cutting‑flute length with safety margin according to stone flatness and actual carving depth to avoid shank abrasion. Example: If carving depth reaches 26 mm, select 30 mm flute length; if carving depth is 15 mm, select 20 mm flute length.
