Seco 02960912 VBMT332-M3 TP1501 Carbide Turning Insert

Product Description

The SECO 02960912 is a solid carbide turning insert in the VBMT-M3 series, designed for precision metal cutting on CNC lathes and turning centers. It carries the industry standard designation VBMT332-M3 and ISO code VBMT160408-M3. The insert features a 35-degree diamond (rhombic) shape with a positive rake and positive side clearance, a 3/8 inch inscribed circle, and a 1/32 inch (0.0315 inch) corner radius. The CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — delivers high wear resistance across finishing and medium machining operations. Two cutting edges per insert and screw-type holding make it a cost-effective choice for high-volume turning applications.

This insert is suited for finishing and medium machining of steel and cast iron components in both residential-shop and industrial production environments. Its M3 chip breaker geometry supports back turning, facing, profiling, and straight turning operations. The TP1501 grade targets ISO material groups P and K, making it applicable to carbon steels, alloy steels, and gray or ductile cast iron workpieces. Maximum depth of cut reaches 0.5748 inch, giving operators meaningful flexibility in roughing passes within the medium-machining range. A licensed machinist or CNC setup technician typically installs and indexes this insert.

Key Features

• VBMT332-M3 geometry with 35-degree diamond shape and positive rake for reduced cutting forces
• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for high wear resistance in steel and cast iron
• M3 chip breaker optimized for finishing and medium machining chip control
• Two usable cutting edges per insert for extended tool life per unit
• Screw-type insert holding method for secure, repeatable positioning
• Meets ANSI and ISO dimensional standards; dual-coded VBMT332-M3 and VBMT160408-M3

Compatibility

Designed as an OEM-compatible replacement or direct-fit insert for VBMT-style screw-lock toolholders conforming to ANSI and ISO VBMT standards, including holders sized for a 3/8 inch inscribed circle insert. Suitable for multi-use applications: back turning, facing, profiling, and turning.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or CNC tooling technician with the machine in a full stop, spindle locked, and all power isolated per shop lockout/tagout procedures. Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the clamping screw — do not overtighten. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Verify seating and runout before returning the machine to production cuts.
