| Code | Feature | Meaning |
|---|---|---|
| A | Shape | 85° parallelogram |
| P | Clearance angle | 11° (positive insert) |
| M | Tolerance class | Class M |
| T | Hole and chipbreaker | Hole countersunk on one side, chipbreaker on one face |
Where APMT inserts are used
The 85° parallelogram is the common shape for 90° shoulder milling cutters, which are also used for face and slot milling.
APMT is a positive (11° clearance) 85° parallelogram milling insert. It has a countersunk hole for a clamping screw. The chipbreaker is on one face only. The positive geometry keeps the cutting forces down.
Use the insert format, size and corner configuration specified by the cutter manufacturer; check the pocket and clamping system before ordering.
