5″ x 9″ Insert Surfacing Head — 6-Wing, Straight Bore

The IN658 faces wide boards and panels in one pass with a 5 in. diameter, a 9 in. cutting length, and six wings for a finer finish at higher feed than the four-wing IN655. The aircraft-aluminum body keeps a long head light enough to run quietly and on modest horsepower. Six wings carry four-sided solid carbide inserts staggered in a spiral across the full 9 in. length, shearing the grain for a line-free surface with 60 effective cutting teeth; the denser edge spacing lets each insert take a lighter bite, which favors surface quality and feed rate. Inserts rotate to fresh edges or replace on or off the machine — no grinding, no regrinds. A constant cutting diameter keeps setup minimal as inserts index, and the reduced cutting pressure supports faster feeds across the wide cut. Specify bore size when ordering.
