WPMT090725ZSR-MH AH140 trigon indexable insert for high-feed milling by Tungaloy

The WPMT090725ZSR-MH AH140 is a trigon-shaped indexable cutting insert optimised for high-feed milling, pocketing and face machining where large volumetric removal is required with shallow axial depths.

• High-feed design for large volumetric removal
• PVD-coated AH140 carbide for chipping resistance
• Trigon shape, 7.94 mm thickness, 80° engagement
• Cylindrical hole with single-sided countersink 40°–60°

Increase throughput with shallow axial depths and high feed rates

The DoFeed series insert delivers improved productivity by enabling substantial material removal while maintaining a small axial depth of cut. As part of a high-feed strategy, the geometry converts higher feed per tooth into faster cycle times, reducing the number of passes needed for pockets and face operations. The result is a measurable gain in throughput and machine utilisation, making this trigon insert particularly suited to production environments where time-efficiency and consistent part quality are priorities. The combination of the DoFeed concept and the insert’s geometry helps to keep cutting forces manageable while boosting the overall material removal rate.

Maintain process security with a wear-resistant PVD-coated grade

The AH140 grade is a PVD-coated carbide selected for its resistance to wear and chipping under milling conditions that demand a sharp edge and reliable tool life. The coating improves thermal stability at the cutting edge and helps preserve a defined geometry over multiple indexings, which supports consistent surface finishes and repeatable cycle times. The integrated MH chipbreaker promotes controllable chip formation, reducing the risk of re-cutting and facilitating evacuation in pocketing operations. These features provide a sound technical basis for predictable machining performance and lower tooling-related downtime.

Stable engagement from controlled geometry and secure clamping

The insert’s trigon form and 80° engagement angle combine with a 2.5 mm corner radius and an 11° clearance to produce a robust cutting interface that resists edge failure during interrupted cuts. The cylindrical hole with a single-sided countersink (40°–60°) ensures precise seating and positive location in compatible tooling bodies, enhancing repeatability and reducing micro-movements under load. At 7.94 mm thickness and size 09, the insert offers a solid contact area for high radial forces, contributing to stable vibrations and improved surface integrity on the workpiece.

Seamless integration into milling systems and typical applications

Designed as a component of the DoFeed system, the insert fits into standard milling bodies with the appropriate screw and seat geometry; the system approach (milling body, matched inserts and screws) simplifies tool assembly and inventory management. Typical uses include high-feed roughing, pocketing and planing operations where high volumetric removal per time unit is required while keeping axial engagement shallow. The engineering behind the insert supports shops seeking to increase batch throughput, reduce cycle counts and maintain consistent results across repeated production runs.
