Product description

MTGNR external turning holder for TNMG inserts

MTGNR indexable holder for external turning, using TNMG 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: 91°.
