Mill 4-12KT has tangentially mounted inserts with four cutting edges per insert for reduced tooling
costs. Seven corner radii from 0.016″ (0.4 mm) to 0.122″ (3.1 mm) are available, along with
coolant-through, medium and coarse pitch cutter bodies 2″ (50mm) to 8″ (200mm) in diameter.
With an axial depth of cut range from 0.019″ to 0.472″ (0.5 to 12mm), Mill 4-12KT covers most
shoulder milling applications.
Multiple factors contribute to significant performance increases, even in aggressive cutting
conditions:
The tangential, “on-edge” insert design also allows the insert to take advantage of the strength of
the carbide thickness more so than radially mounted inserts found on traditional milling cutters.
A shallow pocket design, allows the core size of the cutter body to be very robust.
