Seco 03275908 Turning Insert CCMT21.51-F1 TM1501 Carbide

Product Description

The SECO 03275908 is a solid carbide turning insert in the CCMT series, designed for precision metal cutting on CNC lathes and manual turning centers. It carries the TM1501 manufacturer grade with a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr, which builds wear resistance and extends edge life in demanding cuts. The insert features an 80-degree diamond shape with a neutral hand orientation, a 0.25-inch inscribed circle, and a 1/64-inch corner radius. The F1 chip breaker geometry promotes positive rake cutting with a sharp edge style, making it well suited for finishing and light roughing passes where chip control matters.

This insert is engineered primarily for stainless steel (ISO material code M) and steel (ISO material code P) workpieces across material grades M15, M20, and M25. Typical applications include boring, facing, and turning operations on components requiring consistent surface finish and dimensional accuracy. It is held by screw clamping in standard CCMT-style toolholders. The insert conforms to both ANSI and ISO standards, and its ISO designation is CCMT060204-F1, making it cross-referenceable in international toolholder systems. This insert is sold individually per package with a minimum order quantity of 10 pieces.

Key Features

• Duratomic CVD multilayer coating: TiCN, Al2O3, and Cr for extended tool life on difficult materials
• 80-degree diamond insert shape with positive rake angle of 17 degrees for reduced cutting forces
• F1 chip breaker geometry with sharp cutting edge style suited for finishing and semi-finishing
• Neutral hand orientation compatible with standard CCMT screw-clamp toolholders
• Dual-use cutting edges: 2 usable edges per insert to maximize value per piece
• Conforms to ANSI and ISO standards with cross-reference ISO code CCMT060204-F1

Compatibility

Designed for use in standard CCMT-style screw-clamp turning toolholders conforming to ANSI and ISO specifications. Primary workpiece materials are stainless steel and steel; suitable for boring, facing, and turning operations per manufacturer application data.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer's specified seating method — do not overtighten, as this can fracture the carbide body. Inspect the insert seat and shim for debris before seating a new insert to ensure proper contact and runout control.
