WPMT090725ZSR AH140 — indexable milling insert (high-feed), Tungaloy

the WPMT090725ZSR AH140 is an indexable milling insert designed for high-feed operations and pocket and face milling

• High-feed geometry for large material removal
• PVD-coated carbide grade AH140
• Trigon shape with 2.5 mm corner radius
• Cylindrical hole with 40°–60° countersink

Delivering high material removal with low axial engagement

The DoFeed family is engineered for high-feed milling, enabling large time-material volumes at small axial depths of cut. By combining a dedicated geometry with a PVD-coated carbide grade, the insert achieves efficient chip formation and reduced cutting forces, which leads to higher feed rates without increasing axial engagement. This performance translates into shorter cycle times and a reliable process window for roughing and semi-finishing operations.

Stable cutting and secure seating for consistent results

A trigon plate with a 2.5 mm corner radius and a cylindrical hole with a one-sided countersink (40°–60°) ensures stable clamping in matched milling bodies. The single-sided chipbreaker promotes predictable chip flow and reduces the risk of build-up, while the 11° clearance angle and an approach angle of 80° are optimised for high-feed cuts. These mechanical features together support repeatable dimensional accuracy and surface integrity on workpieces.

Coating and grade engineered for process reliability

The AH140 grade is a PVD-coated carbide specifically selected for wear and edge-break resistance in milling applications. Its coating enhances thermal stability and abrasion resistance, helping to maintain a sharp cutting edge under intermittent or high-load conditions. This makes the insert suitable where a combination of sharpness and process security is required, supporting longer tool life and fewer indexings.

System integration and application scope

As part of a complete milling system, the insert is intended for use with corresponding milling bodies and screws; correct pairing ensures optimal seat contact and torque transmission. Typical uses include high-feed milling, pocket machining and face milling where high metal removal rates at low axial depths are sought. The design supports machining of a broad range of materials when the right cutting data are applied.

Practical advantages for workshop operation

Using this insert in a matched DoFeed setup reduces setup complexity and improves throughput. The already assembled system approach—milling body, matched inserts and fastening screws—simplifies inventory management and shortens tool-change times. The combination of high-feed geometry and a wear-resistant PVD coating contributes directly to reliable day-to-day production and predictable maintenance intervals.
