Seco 02615993 Cnmg 432-MF4 TS2500 Turning Insert Carbide

Product Description

The SECO 02615993 is a solid carbide turning insert in the CNMG 432-MF4 series, designed for precision metal cutting in CNC turning, boring, and facing operations. It carries a multilayer PVD TiAlN and TiN coating over a carbide substrate, pairing moderate-to-high wear resistance with toughness suited to demanding workpiece materials. The insert features an 80-degree diamond (rhombic) shape, a 0.5 inch inscribed circle, a 0.0315 inch corner radius, and 4 usable cutting edges. The MF4 chip breaker geometry is optimized for finishing and medium machining passes. Machinists and CNC operators in production and job-shop environments install this insert in compatible toolholders using clamp, pin, or lever-lock holding methods.

The 02615993 is suited for turning superalloys and titanium as its primary workpiece materials, with strong secondary performance on steel, stainless steel, and cast iron. The TS2500 grade provides a balance of wear resistance and toughness across ISO application categories P, M, K, and S, making it a versatile choice for mixed-material production runs. Typical applications include external and internal diameter turning, facing cuts, and boring on CNC lathes. The neutral hand orientation allows use in standard toolholder configurations without handedness restrictions.

Key Features

• CNMG 432-MF4 geometry with 80-degree diamond insert shape and negative rake for stable, controlled cutting
• Multilayer PVD TiAlN and TiN coating for high wear resistance and thermal protection
• TS2500 carbide grade rated for steel (P), stainless steel (M), cast iron (K), and superalloys and titanium (S)
• MF4 chip breaker optimized for finishing and medium machining chip control
• 4 cutting edges per insert for extended tool life per insert consumed
• Compatible with clamp, pin, and lever-lock toolholder systems; neutral hand orientation

Compatibility

Designed for use in CNMG-style toolholders that accept a 432 size code insert (ANSI CNMG432, ISO CNMG120408). Compatible holding methods include clamp, pin, and lever-lock systems. Suitable for boring, facing, and turning applications on CNC lathes.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before seating or replacing inserts. Verify that the toolholder pocket is clean and free of chips or debris before installing the insert, as contamination under the insert seat affects dimensional accuracy and can cause premature edge failure. Do not overtighten clamping screws beyond the toolholder manufacturer's specified procedure; refer to the toolholder documentation for correct clamping method and torque guidance.
