Feature 1: The tip of the tools is designed with 6mm diamond without an iron bar, providing a longer working life and increased durability. It is specifically engineered for engraving hard granite.
Feature 2: The tool body features multilayer diamonds, ensuring sharpness and high wear resistance.



Standard angle alloy knife, cost-effective, easy to re-grind! Suitable for inscribed characters; milling of small characters; tombstone carving; and fine reliefs. For engraving granite, one cut should not exceed 0.6 mm.

Handle Diameter: Prefer 8MM for reliefs within 2cm, and 10MM for those above 2cm. High-speed requirements may use 12MM tool holders.
Tip Size: Larger tips ensure longer life. If 6MM meets accuracy needs, avoid 3MM or 4MM tips.
Blade Length: Choose a length with a margin based on carving depth. For example, use a 30MM blade for a 26MM depth.
