Designed for router table use, this set can be used to create slots, grooves and rebates from 3.2mm to 18mm in depth. The set includes: 4 x three winged cutters 3.2, 4, 4.8, and 6.4mm in width. 1/2" shank arbor. 21 shims (8 x 0.1mm, 4 x 0.5mm, 5 x 1mm, 2 x 3mm and 2 x 6mm).
N.B. The carbide edges of the cutters should never touch; arrange the cutters to prevent this. Use only the thicknesses provided in the set.

The distance between the cutters can vary from 1mm to 1.5mm. A shim must also be positioned between the ball bearing and the cutters.
