Seco 02615995 Wnmg 432-MF4 TS2500 Carbide Turning Insert

Product Description

The SECO 02615995 is a WNMG 432-MF4 indexable turning insert manufactured from solid carbide with a multilayer PVD TiAlN and TiN coating. The insert carries grade designation TS2500 and features an 80-degree trigon (W) shape with a neutral hand orientation and a negative rake geometry. With a 0.5000-inch inscribed circle, a 0.0315-inch corner radius, and an insert thickness of 0.1874 inches, it delivers repeatable edge geometry across six usable cutting edges. The MF4 chip breaker geometry and chamfered-and-honed cutting edge style are designed to manage chip control and edge stability during demanding material removal operations. Licensed machinists and CNC turning specialists are the primary installers of this insert.

This insert is engineered primarily for machining superalloys and titanium (ISO material code S, material grades S10 and S20). It is also suited for secondary applications in steel, stainless steel, and cast iron (ISO codes P, M, and K). Typical application scenarios include external and internal boring, facing, and turning operations on CNC lathes and turning centers where tight tolerances and difficult-to-machine workpiece materials demand a durable, wear-resistant coated carbide edge. The MF4 chip breaker is particularly effective in light-to-medium finishing and semi-finishing passes on these material families.

Key Features

• TS2500 carbide grade with multilayer PVD TiAlN and TiN coating for thermal resistance in superalloy and titanium cutting
• WNMG 432-MF4 geometry: 80-degree trigon shape, neutral hand, negative rake, chamfered and honed edge
• Six usable cutting edges per insert for extended tooling economy
• MF4 chip breaker optimized for chip control in finishing and semi-finishing passes
• Compatible with clamp, pin, and lever-lock insert holding methods
• Conforms to ANSI and ISO standards; ISO designation WNMG080408-MF4
• Multi-use capability across boring, facing, and turning operations

Compatibility

Designed for use in WNMG-style indexable toolholders that accept clamp, pin, or lever-lock insert retention. Fits toolholders conforming to ANSI and ISO WNMG 432 / WNMG080408 insert seat specifications.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist with the machine spindle fully stopped and all energy sources locked out per facility LOTO procedures. Use the appropriate torque wrench and manufacturer-specified fastener for the toolholder clamping system to seat the insert correctly without cracking the carbide substrate. Inspect the insert pocket and seating surfaces for chips or debris before seating a new edge. Discard inserts showing edge chipping, cratering, or coating delamination rather than attempting to reuse a degraded cutting edge.
