Benefits

Narrow water slots

Because of the high power of the machine, the blades are fitted with narrow water slots that give a wider segment and longer service life.
Smooth start

The shape of the segment means that you get a smooth and free-cutting start when applying a new blade in concrete.
Undercut prevention

To prevent undercutting, all diameters are equipped with a guard in the form of a support segment or recessed drop segment.
