Seco 02956306 Ccmt Turning Insert 3/8 in Ic 80 Diamond

Product Description

The SECO 02956306 is a CCMT-series indexable turning insert designed for general-purpose metal cutting in CNC and manual turning applications. It features an 80-degree diamond shape with a neutral hand orientation and carries a CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — engineered for wear resistance and thermal stability. The inscribed circle measures 0.375 inches, insert thickness is 0.1563 inches, and the corner radius is 0.0079 inches (1/128 inch). With 2 cutting edges and an MF2 chip breaker geometry, this insert is suited for finishing and medium turning passes on steel and related materials. It is installed via a screw-lock holding method.

This insert is intended for boring, facing, and turning operations on steel as the primary workpiece material, with secondary application on stainless steel and cast iron. It carries material grade designations P10, P20, P30, and P35, making it a versatile choice across a range of steel hardness levels in both roughing-adjacent and finishing contexts. The MF2 chip breaker geometry promotes reliable chip control at light-to-moderate depths of cut. Typical users include CNC machinists and toolroom professionals working in job shop, production machining, and maintenance environments.

Key Features

• 80-degree diamond insert shape (CCMT style) with neutral hand orientation for flexible tool path use
• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for extended tool life on steel
• MF2 chip breaker geometry optimized for finishing and medium turning on steel and stainless
• Screw-lock insert holding compatible with standard CCMT toolholders
• 2 cutting edges per insert; multi-use across boring, facing, and turning applications
• Chamfered and honed cutting edge for improved edge stability and reduced chipping

Compatibility

Designed for use in standard CCMT-compatible screw-lock turning toolholders. Primary workpiece material is steel (ISO code P); secondary materials include stainless steel (M) and cast iron (K). ISO designation CCMT09T302-MF2 and industry standard number CCMT32.50.5-MF2 apply. Conforms to ANSI and ISO standards.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool is secured in the holder before indexing or replacing the insert. Use the appropriate torx or hex key to tighten the clamp screw to the toolholder manufacturer's specified procedure — do not overtighten, as this can fracture the carbide substrate. Verify correct seating of the insert in the pocket before resuming cutting operations.
