Disclosed is a rotary slot milling cutter (20) having a plurality of cutting portions (30), each cutting portion (30) comprising an insert pocket (42) and a cutting insert (38) removably mounted therein. The cutting insert (38) comprises a top face (52) and a bottom face (54) comprising two spaced-apart abutments (92), with a ceiling (100) formed therebetween. The insert pocket (42) has a generally axially disposed pocket base (108) comprising two support surfaces (110, 110') and a radially extending rib (112) disposed therebetween, the rib (112) comprising a roof (116) and two banks (114). When the cutting insert (38) is mounted in the insert pocket (42), the abutment platforms (96) abut the support surfaces (110, 110), and a gap (118) exists between the roof (116) of the rib (112) and the ceiling (100), and between each side slope (102) and adjacent banks (114). |
