Product description

SCMCN-100 (obtuse) external turning holder for CCMT inserts

SCMCN-100 (obtuse) indexable holder for external turning, using CCMT inserts. Clamping: screw through the insert hole (s). 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: 40°.

Insert seat and insert size

12	CCMT 1204

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.

Reading the variant designation

Code element	Meaning

R / L / N	Right-hand / left-hand / neutral
Two pairs of digits after the letters	Shank width and height [mm]
Letter following shank size	Holder length designation
Code suffix	Insert seat size

Tool selection

Check the insert family, seat size, shank, holder length and R/L/N design together. Choosing an insert grade for steel, cast iron, aluminium or another material does not change the required fit between insert and holder seat.
