Carbide APMT PVD Coated inserts are commonly used for indexable square shoulder end milling cutters and face milling cutters. They are intended for machining stainless steel.
The APMT inserts are with precision moulded I.C., positive moulded chipbreaker. They have sharp and honed cutting edge and 11° relief angle. They are with screw holes created in compliance with ISO. Typically, it is viewed as with 2 cutting-edges. However, they actually 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 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. The inserts have cutting edges on 1 side. They are TiN coated, which enable the inserts to work longer and are able to run at faster speeds than uncoated inserts.
When a cutting edge of the APKT insert becomes dull, you just need to rotate the insert in the holder to use the sharp edge.
