Iscar 5502463 Turning Insert Vnms 331-12 Solid Carbide

Product Description

The ISCAR 5502463 is a solid carbide uncoated turning insert in the Isoturn series, designed for single-end external turning and boring operations. It follows the VNMS 331-12 ISO designation, featuring a 35-degree diamond insert shape with a positive rake geometry and a neutral clearance angle. The inscribed circle measures 3/8 inches, the insert length is 0.654 inches (16.61 mm), the thickness is 3/16 inches, and the corner radius is 1/64 inches. This insert is installed by machinists and CNC turning specialists working across a broad range of workpiece materials.

This insert is rated for universal primary workpiece material compatibility, covering ISO material codes H, K, M, N, and S. It is suited for use in production turning, facing, and boring applications on CNC lathes and turning centers. The maximum depth of cut is 0.118 inches (3.00 mm). The chip breaker designation is 12. It is held in place using a clamp-and-pin method, making it compatible with standard toolholders designed for VNMS-style inserts. Typical applications include light to medium finishing and semi-finishing passes.

Compatibility

Designed for use in VNMS-style toolholders compatible with the Isoturn series. Suitable across universal workpiece materials per ISO codes H, K, M, N, and S. Confirm toolholder acceptance of VNMS 331-12 insert geometry before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before changing inserts. Seat the insert fully against the toolholder pocket and secure with the clamping pin to the manufacturer torque specification for the toolholder used. Inspect the insert pocket and seating surface for chips or debris before each insert change to prevent insert rock or breakage.
