Iscar 3344996 Turning Insert Ccmt 3/8 in IC804 Carbide

Product Description

The ISCAR 3344996 is a single-tipped solid carbide turning insert in the CCMT style, designed for precision external and internal turning operations on CNC and manual lathes. It carries ISCAR IC804 grade carbide with a proprietary SumoTec coating, which is engineered for wear resistance and thermal stability during continuous and light interrupted cuts. The insert has an inscribed circle of 0.3750 inches, an overall length of 0.3820 inches, and a corner radius of 0.16 mm. The PF chip breaker geometry promotes controlled chip formation during finishing passes in steel and similar materials.

This insert is suited for finishing and semi-finishing turning applications in shop environments running steel, alloy steel, and similar workpiece materials. The CCMT shape features a 80-degree diamond profile with a 7-degree clearance angle and a medium tolerance class. It seats into standard CCMT-style toolholders used widely in production and job-shop turning cells. The PF chip breaker geometry is particularly effective at lower depths of cut and moderate feed rates typical of finishing operations. Machinists and CNC operators performing close-tolerance turning work will find the IC804 grade well matched to these conditions.

Key Features

• IC804 grade solid carbide with SumoTec coating for wear and thermal resistance
• CCMT insert style: 80-degree diamond shape, 7-degree clearance angle, medium tolerance
• PF chip breaker geometry optimized for finishing and light semi-finishing cuts
• 0.16 mm corner radius for tight-tolerance surface finish requirements
• 3/8 inch (0.3750 inch) inscribed circle in a compact single-tipped form factor
• Solid carbide construction throughout for consistent edge integrity

Compatibility

Designed for use in standard CCMT-style turning toolholders accepting a 3/8 inch inscribed circle insert with a 3-1 size code. Confirm toolholder pocket dimensions and seating geometry before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the correct torque wrench and manufacturer-specified clamp screws to secure the insert; do not overtighten by hand. Inspect the pocket seat and clamp hardware for wear or debris before installing a new insert to ensure proper seating and edge repeatability.
