Ingersoll Cutting Tools 5515254 Turning Insert WNMG432MT

Product Description

The INGERSOLL CUTTING TOOLS 5515254 is a WNMG432MT TT8020 grade solid carbide turning insert designed for precision metal removal on CNC lathes and turning centers. Coated with TiCN via PVD process, this insert delivers improved wear resistance and edge integrity on demanding workpiece materials. It features a neutral hand orientation, an 80-degree trigon insert shape, a 0.5-inch inscribed circle, and a 1/32-inch corner radius. The MT chip breaker geometry promotes controlled chip formation during turning operations. Licensed machinists and CNC operators working in production and job-shop environments install and index this insert type as part of routine tooling maintenance.

This insert is intended for turning stainless steel, carbon and alloy steel, and super-alloys including titanium - material groups corresponding to ISO classifications M, P, and S. It fits standard WNMG-style toolholders using a clamp holding method and is appropriate for both roughing and finishing passes within its maximum depth of cut. Typical applications include shaft turning, facing, and contour operations on medium to heavy CNC lathes in residential shop, production floor, and industrial machining environments.

Key Features

• TT8020 grade solid carbide substrate with PVD TiCN coating for extended tool life on stainless steel and super-alloys
• MT chip breaker geometry for controlled chip evacuation during turning
• 6 usable cutting edges per insert for cost-effective tooling use
• Negative rake, 0-degree relief angle (clearance code N, tolerance code M) for stable edge support
• Maximum depth of cut of 0.157 inches suitable for medium stock removal
• ISO-standard geometry (ISO Code: WNMG080408MT TT8020) for broad toolholder compatibility

Compatibility

Designed for use in WNMG-style clamp-type toolholders accepting a 1/2-inch inscribed circle trigon insert. Compatible with material grades C1 through C6 and ISO material groups M, P, and S. ANSI code WNMG432MTTT8020; ISO code WNMG080408MT TT8020.

Installation Notes

Indexing and insert changes should be performed by a qualified machinist or CNC tooling technician with the machine fully stopped and in a safe, locked-out state. Seat the insert firmly in the toolholder pocket and tighten the clamp per the toolholder manufacturer's specifications before resuming cuts. Inspect the insert pocket and clamp for wear or debris before seating a new insert. Dispose of worn carbide inserts in accordance with applicable shop safety and waste-handling procedures.
