| Code | Feature | Meaning |

| M | Tolerance class | Class M |
| W | Hole and chipbreaker | Hole countersunk on one side, no chipbreaker |
Where RDMW inserts are used
Round milling inserts are used in profile (copy) milling, face milling and high-feed cutters; the round edge is strong.
RDMW is a positive (15° clearance) round milling insert. It has a countersunk hole for a clamping screw. It has no chipbreaker (a flat top). 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.
