Technical Application Guide

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.
