Seco 02956305 Ccmt Turning Insert 1/4 in Carbide

Product Description

The SECO 02956305 is a CCMT-style solid carbide turning insert designed for precision metal cutting in CNC and manual turning operations. It features a CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — that extends tool life on ferrous materials. The insert has an 80-degree diamond shape, a 1/4-inch inscribed circle, a 1/32-inch corner radius (0.0315 inches), and 2 cutting edges. Insert thickness is 3/32 inches (0.0937 inches) and insert length is 0.2559 inches. The MF2 chip breaker geometry promotes positive rake cutting with a chamfered and honed edge. Screw-hold mounting and a clearance hole diameter of 0.1142 inches are standard. This insert is used by machinists and CNC operators in production and job-shop environments.

The 02956305 is suited for boring, facing, and turning operations at light to medium depths of cut up to 0.2205 inches. The primary target workpiece material is steel, with secondary compatibility for stainless steel and cast iron, corresponding to ISO material codes P, M, and K. Material grades P10, P20, P30, and P35 are covered. The neutral hand orientation makes it compatible with standard right-hand toolholders used in typical OD turning setups. The MF2 chip breaker is optimized for finishing and medium finishing passes where chip control and surface finish are priorities.

Key Features

• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for extended tool life on steel and stainless
• 80-degree diamond insert shape with positive rake for reduced cutting forces
• MF2 chip breaker geometry supports finishing and medium finishing cuts
• Chamfered and honed cutting edge for edge strength and surface finish quality
• 2 cutting edges per insert for cost-effective indexing
• Conforms to ANSI and ISO standards; ISO code CCMT060208-MF2

Compatibility

Designed for use in CCMT-style screw-clamp toolholders accepting a 1/4-inch inscribed circle insert. Compatible with boring, facing, and turning applications on steel, stainless steel, and cast iron workpieces. Conforms to ANSI and ISO CCMT insert standards for interchangeability with compliant toolholder systems.

Installation Notes

Installation is performed by machinists or CNC setup technicians using standard torx or hex keys per toolholder manufacturer specifications. Power down and lock out the machine spindle before indexing or replacing inserts. Do not overtighten the clamping screw, as this can fracture the carbide body. Inspect the insert pocket and seating surface for chips or debris before seating a new insert to ensure proper contact and runout.
