Cutterhead set for concave grooves Ø148

This set is designed to cut perfect concave grooves into the workpiece or on the edge of the workpiece. By inserting some spacers between the two elements (included in this set) you can adjust the precision of the radius produced. It is not possible to work with only one of the two elements, which compose this set. 3 different sizes of radius knives can be fitted on this cutterhead. The knives are made of hard metal (HW). On each cutterhead three knife sizes can be fitted: on the smaller cutterhead it is possible to fit the knives of radius 12,5 mm, 15 mm and 17,5 mm, while on the bigger one the knives of radius 20 mm, 22,5 mm and 25 mm.
