When milling, the guide sleeve runs along the contour of the template. This transfers shapes onto the workpiece, making it indispensable when working with templates. The bayonet lock allows for quick, tool-free changes. The distance between the sleeve and the milling bit must be considered when creating a template. This distance is calculated using the following formula: diameter of the guide sleeve (K) minus the diameter of the cutter (F) divided by 2. Diameter mm: 24.00.
