Seco 03310374 CCMT32.52-M3 TP25 Carbide Turning Insert

Product Description

The SECO 03310374 is a CCMT-series indexable turning insert designed for precision metal cutting in CNC and manual turning applications. Manufactured from solid carbide with a multilayer CVD coating of TiCN, Al2O3, and Cr, this insert carries the TP25 manufacturer grade and is engineered for cutting steel as its primary workpiece material. The insert features an 80-degree diamond shape, a 0.0315-inch corner radius, and an M3 chip breaker geometry with a positive rake angle of 18 degrees and a chamfered and honed cutting edge style. It provides 2 cutting edges per insert and is held in the toolholder by screw clamping.

This insert is suited for boring, facing, and turning operations on steel, stainless steel, and cast iron workpieces. The TP25 grade and M3 chip breaker combination targets general-purpose steel finishing and medium machining, fitting material grades P20, P30, and P35. It conforms to both ANSI and ISO standards, with an ISO code of CCMT09T308-M3 and an industry standard number of CCMT32.52-M3, making it a direct fit for toolholders designed around the CCMT 32.52 insert pocket specification.

Key Features

• Multilayer CVD coating (TiCN, Al2O3, Cr) for wear resistance and heat dissipation on steel and stainless
• TP25 carbide grade rated for P20, P30, and P35 material groups
• 80-degree diamond insert shape (Shape Code C) with 7-degree relief angle and positive rake
• M3 chip breaker geometry optimized for boring, facing, and turning
• Chamfered and honed cutting edge for edge stability on interrupted and continuous cuts
• Neutral hand orientation; compatible with standard CCMT screw-lock toolholders
• Dual cutting edges per insert extend usable tool life

Compatibility

Designed for use in CCMT 32.52 screw-lock toolholders conforming to ANSI and ISO CCMT09T308 pocket specifications. Suitable for steel, stainless steel, and cast iron workpieces per ISO material codes P, M, and K.

Installation Notes

Installation is performed by machining technicians using the appropriate Torx or hex key for the insert clamping screw specified by the toolholder manufacturer. Always index or replace the insert with the spindle fully stopped and the machine in a locked-out state. Inspect the toolholder pocket and clamping screw for wear or debris before seating a new insert. Do not exceed the maximum depth of cut of 0.3504 inches as stated in the product specifications.
