Sandvik Coromant 8194196 Cut-off Insert Carbide Grade 1225

Product Description

The SANDVIK COROMANT 8194196 is a carbide cut-off and parting insert designed for use on CNC lathes and turning centers performing grooving, parting, and cut-off operations. It belongs to the CoroCut 2 series and carries a G2 insert size code with C2I insert style. The insert features a 0.1181-inch (3.00 mm) cutting width and is coated with a multilayer PVD TiAlN/TiAlSiN/TiSiN stack, Grade 1225. The CM chipbreaker geometry and left-hand cutting direction make it suited to specific toolholder configurations. A licensed machinist or CNC toolroom technician installs and indexes this insert.

This insert is intended for cut-off and parting applications on steel and stainless steel workpieces, corresponding to ISO material codes P and M respectively. The left-hand lead angle and left-hand insert orientation require a compatible left-hand CoroCut 2 toolholder. The G insert seat size and G2 size code must match the toolholder pocket exactly. Typical applications include OD parting on bar-fed lathes and production turning cells where consistent chip control and edge life are critical. The ISO designation for this insert is C2I-G2N-0300-0002-CM1225.

Compatibility

Designed for use with compatible left-hand CoroCut 2 series toolholders requiring a G insert seat size and G2 insert size code, as specified by the ISO code C2I-G2N-0300-0002-CM1225. Verify toolholder pocket specifications before installation.

Installation Notes

A qualified machinist or CNC toolroom technician should install this insert with the machine fully powered down and the spindle locked. Use the appropriate torque wrench and clamping screw specified for the CoroCut 2 toolholder to secure the insert without over-tightening. Inspect the insert seat and clamp for chips or wear before seating the new insert. Never run the insert in a toolholder pocket that does not match the G2 seat size, as improper seating can cause insert failure and workpiece damage.
