Single-edged cutter (Z1): Reduced heat generation minimizes burn marks when milling across the grain. Special cutter for rounding edges. Cutter radius precisely matched to the ball bearing. To protect the surface, the radius at the cutting edge transitions into a 5° taper. Low construction height: The flush ball bearing attachment of the cutter allows for milling in grooves or from a stack of panels. The rounding cutter is specifically designed for delicate, small-scale work on edges. It is primarily used for solid wood, but also for plastic edges. The special hollow shaft cutter sits directly on the spindle, ensuring very high run-out accuracy and a clean milling pattern.
