Product description

MDJNL / MDJNR external turning holder for DNMG inserts

MDJNL / MDJNR indexable holder for external turning, using DNMG inserts. Clamping: top insert clamp. The final letter R, L or N in the five-letter holder designation identifies its hand.

Shank size, holder length and insert seat size are separate parameters. Read the selected variant designation before choosing an insert; shank width alone does not determine compatibility.

Application

For machining external workpiece surfaces on a lathe. Select R or L according to the required tool orientation; N identifies the neutral design. Choose the insert geometry, cutting grade and machining parameters for the operation and workpiece material.

Entering angle of this design: 93°.

Insert seat and insert size

The size designation does not specify corner radius, grade or chipbreaker. Select these insert features separately while preserving compatibility with the seat geometry and dimensions.
