Selection Guidelines
Handle Diameter: 8MM shank is preferred for reliefs within 2cm; 10MM shank for reliefs above 2cm. 12MM holders are ideal for high-speed CNC operations.
Tip Size: Larger tips offer longer tool life. Choose a larger tip size whenever it meets the accuracy requirements of the project.
Blade Length: Select a length with a margin based on carving depth to prevent tool handle contact with the material.
