Abstract
A router tool and a cutting insert for transverse cutting of a work piece, preferably of fiber reinforced plastics. The router comprises a shank and a cylindrical router body having chip gullets and sites that have received cutting inserts. Each insert has a cutting edge which has a number of teeth extending in the rotational direction of the router. The inserts are staggered in the axial direction such that the router varying will present a right-handed cutting edge portion and a left-handed cutting edge portion whereby the work piece may be machined without producing defective burrs and fluffy fibers.
