Seco 02615921 Turning Insert Wnmp 332-MF1 TS2000 Carbide

Product Description

The SECO 02615921 is a solid carbide trigon turning insert in the WNMP-MF1 series, grade TS2000, designed for precision metal cutting on CNC lathes and turning centers. It carries a multilayer PVD coating of TiAlN and TiN, which extends tool life and supports elevated cutting temperatures. The insert features an 80-degree included angle, a 3/8-inch inscribed circle, a 1/32-inch corner radius, and a negative rake geometry with a honed cutting edge. Six cutting edges are available per insert. The MF1 chip breaker geometry is engineered for controlled chip formation in medium finishing operations. Machinists and CNC operators working in job shops, aerospace, and general manufacturing will find this insert well-suited for finishing and semi-finishing passes.

This insert is primarily rated for stainless steel and superalloys and titanium, material codes M and S, per ISO classification. Secondary workpiece materials include steel, cast iron, and hard materials, codes P, K, and H. Typical applications include boring, facing, and turning operations. The insert is compatible with clamp, pin, and lever lock holding methods, making it adaptable to a wide range of standard toolholders. The ISO equivalent designation is WNMG060408-MF1, which can assist in cross-referencing compatible toolholder systems and competing grades.

Key Features

• 80-degree trigon insert shape (W) with negative rake and honed cutting edge for improved edge stability
• MF1 chip breaker geometry optimized for medium finishing on stainless steel, superalloys, and titanium
• Six usable cutting edges per insert for extended cost-per-edge value
• Compatible with clamp, pin, and lever lock toolholder clamping methods
• Conforms to ANSI and ISO standards; ISO equivalent WNMG060408-MF1

Compatibility

Designed for use in standard WNMP-style toolholders that accept a trigon insert with a 3/8-inch inscribed circle, 0.1500-inch hole diameter, and clamp, pin, or lever lock clamping. Compatible with toolholder systems conforming to ANSI and ISO WNMG060408-MF1 specifications. Suitable for multi-use applications including boring, facing, and turning.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Always power down and lock out the machine before seating or indexing the insert. Ensure the insert pocket and clamping surfaces are clean and free of chips or debris before installation, as contamination can cause insert rocking and premature edge failure. Torque clamping screws per the toolholder manufacturer specifications and verify insert seating before resuming cuts.
