APKT positive-rake parallelogram milling inserts are used to machine aluminum. The carbide uncoated parallelogram milling inserts have an offset rectangle shape with four sides and two acute (85°) cutting points at opposite corners. They are mounted to a compatible tool holder / indexable milling cutter / indexable shell milling cutter / indexable face milling cutter, which is attached to a milling machine.
They can be replaced with new inserts of the same type or different types without removing the tool holder cutter from the machine. Indexable milling cutters require fewer tool changes than solid cutters in high-volume metalworking and fabrication applications with high speeds, high feeds, and difficult-to-machine objects.
The uncoated carbide APKT inserts are designed with a polished surface and large rake angle. They are intended for machining Aluminum. The positive-rake feature enables the inserts to have an edge that is less than 90° to sit flat in the insert holder for improved cutting clearance and a better finish than negative-rake ones.
When the cutting edge of the APKT insert becomes dull, you just need to rotate the insert in the holder to use the sharp edge. The APKT inserts are with precision-molded I.C., positive molded chip breaker. They have a sharp and honed cutting edge and 11° relief angle. They are with screw holes created in compliance with ISO. Typically, it is viewed with 2 cutting edges. However, they have 4 cutting edges. when they are installed on 90° indexable milling cutters and both edges become dull, they can be installed on 75° indexable milling cutters and continue other milling applications with the other two edges.
The APKT inserts are designed not only for the general-purpose milling application but also for high-performance milling applications. The milling jobs it can be applied are from roughing to finishing applications. Beyond, you may use the APKT carbide inserts with medium to high cutting speeds with a high rate of material removal.
