WNGU090408 AH725 – Trigon indexable insert for milling, PVD-coated carbide by Tungaloy

The WNGU090408 AH725 is an indexable milling insert designed for Tungaloy milling systems, optimised for plan, shoulder, slot and high-feed contour milling applications

• AH725 PVD-coated carbide for robust performance
• Suitable for steel and stainless steel machining
• Trigon insert, 0.8 mm corner radius, 80° lead
• Central hole with cylindrical hole and countersink

Consistent process security for mixed-material batches

The combination of the AH725 grade and a PVD-coated carbide substrate delivers reliable, repeatable cutting behaviour across varying components. The grade is engineered to be fracture-resistant, which reduces unexpected edge failures when switching between mild steel and stainless steel, making the insert especially suitable where job batches or tool diameters change frequently. This results in fewer tool changes and a more predictable production rhythm, supporting higher machine utilisation.

Geometry and mounting designed for stable clamping and accuracy

The trigon plate form with a 0.8 mm corner radius and an 80° lead concentrates cutting forces into a compact edge geometry that keeps the cutting line stable during shoulder and contour passes. The insert is supplied with a central hole (cylindrical hole plus double-sided countersink 40°–60°) to match Tungaloy clamping systems, ensuring correct seating and torque distribution via the clamping screw and backing shim. Correct seat and geometry matching are essential; the insert must be used with compatible holders for secure clamping and repeatable positioning.

Chip control and double-sided use for uptime and economy

A double-sided chipbreaker design and a plate thickness of 4.76 mm permit indexing to an unused cutting edge, effectively doubling edge life per insert and lowering tooling cost-per-part. The chipformer is balanced for medium to high feeds typical of planing and slotting operations, improving swarf evacuation and reducing re-cutting of chips. The result is steady surface quality and fewer interruptions, particularly in shorter cycle, high-throughput environments.

Practical benefits for workshop integration and tool selection

This insert is part of the dedicated series for Tungaloy milling systems and must match the corresponding pocket, geometry and cutter body. The size designation 09, combined with the 0.8 mm corner and the universal AH725 grade, makes the insert a flexible choice for small to medium cutter diameters where both productivity and process stability are priorities. Selecting the correct insert-seat combination simplifies inventory and helps maintain constant machining results across batches.

FAQ

What materials is this insert suitable for?
The WNGU090408 AH725 insert is specified for machining steel and stainless steel and is designed as a universal, fracture-resistant grade for mixed‑material production.

How does the insert improve process security?
The AH725 grade with PVD coating and the insert’s geometry reduce edge failure and deliver consistent cutting forces, which enhances process security during varied milling tasks.

Can the insert be indexed and reused?
Yes, the trigon plate is double-sided with a double-sided chipbreaker, allowing indexing to a fresh edge and extending tool life per insert.

What must be checked before assembly into a cutter body?
Ensure the insert seat, plate geometry and cutter body are technically compatible and that the clamping screw and backing shim match the central hole and countersink specifications.

Is this insert compatible with Tungaloy milling systems only?
The insert is intended for use in Tungaloy milling systems where seat and geometry match; using it in incompatible bodies may compromise clamping and performance.
