Seco 02960838 Ccmt Turning Insert 3/8 Inch Ic Carbide

Product Description

The SECO 02960838 is a CCMT-style indexable turning insert designed for precision metal cutting on CNC lathes and manual turning centers. Built from solid carbide with a multilayer CVD Duratomic coating of TiCN, Al2O3, and Cr, this insert delivers wear resistance and thermal stability across a wide range of cutting conditions. Key specifications include a 3/8-inch inscribed circle, a 7-degree relief angle, an 80-degree diamond shape, and a 1/128-inch (0.0079 inch) corner radius. The M3 chip breaker geometry produces positive rake cutting action suited for light-to-medium roughing and finishing passes. Neutral hand orientation and a screw-type holding method make installation straightforward for machinists and toolroom technicians.

This insert is intended for turning, boring, and facing operations. Its primary workpiece material is steel, with secondary suitability for stainless steel and cast iron, corresponding to ISO material codes P, M, and K. Material grade coverage spans P10 through P35, making it appropriate for both finishing and semi-roughing applications in production and job-shop environments. The CCMT form factor is widely used in general-purpose external and internal turning toolholders. A maximum depth of cut of 0.3740 inch supports moderate material removal rates without sacrificing edge integrity.

Key Features

• Multilayer CVD Duratomic coating: TiCN, Al2O3, and Cr for extended tool life on steel and stainless
• 80-degree diamond insert shape with chamfered and honed cutting edge for controlled chip formation
• M3 chip breaker geometry with positive rake — suited for finishing and light roughing
• 2 cutting edges per insert, multi-tipped construction maximizes value per unit
• Screw-type holding method provides secure seating and repeatable indexing
• Compatible with boring, facing, and turning applications from a single insert style

Compatibility

Designed for use in CCMT-style turning toolholders conforming to ANSI and ISO standards. ISO code equivalent is CCMT09T302-M3. Industry standard number CCMT32.50.5-M3 governs toolholder compatibility. Verify toolholder insert pocket specifications before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to torque the clamp screw to the toolholder manufacturer's specification — do not over-tighten, as carbide inserts are brittle and susceptible to cracking under side-load clamping stress. Confirm proper seating and edge orientation before resuming cuts.
