WNGU 090416 AH130 Tungaloy trigon insert for milling – 80° geometry, 1.6 mm corner radius

A WNGU090416 AH130 trigon indexable insert designed for milling applications such as face, shoulder, slot and high-feed milling within compatible Tungaloy milling systems.

• Trigon insert WNGU090416 AH130
• PVD-coated carbide, wear-resistant
• Cylindrical hole with double countersink

Consistent process security through coated carbide technology

The insert uses a PVD-coated carbide grade (AH130) developed for resistance to wear and chipping during milling. The coating increases surface hardness and reduces adhesive wear, while the cemented carbide substrate maintains toughness at the cutting edge. For production this combination results in stable tool life and fewer unplanned tool changes, which supports predictable cycle times and repeatable component quality.

Geometry engineered for strength and edge stability

A trigon shape with an included angle of 80° and a 1.6 mm corner radius offers a balanced compromise between edge strength and achievable surface finish. The trigon form provides three indexed cutting edges per side where applicable, delivering cost-effective edge utilisation. The moderate corner radius improves resistance to edge chipping under interrupted cuts, while the 80° geometry concentrates cutting forces for robust material removal in shoulder and face milling.

Secure clamping and reliable chip control for productivity

The insert is supplied with a cylindrical hole and a double-sided countersink (40°–60°), enabling precise and repeatable clamping in matching tool bodies; this reduces micro-movement and helps maintain the sharp cutting line. The double-sided chipbreaker assists controlled chip formation across a range of feeds, lowering the risk of built-up edge and promoting consistent surface quality. Together these design elements contribute to higher process reliability and improved productivity in series production.

Practical selection and system compatibility guidance

The insert belongs to an indexable milling insert series that requires matching insert seat, geometry and cutter body within Tungaloy systems; mixed assemblies can compromise clamping and cutting performance. When selecting a toolbody, ensure compatibility with the WNGU form and the AH130 grade to exploit the insert’s wear resistance and edge security.

FAQ

What materials is this insert suitable for?
The WNGU090416 AH130 insert from Tungaloy is specified for general milling operations; the AH130 grade is optimised for wear resistance and fracture resistance across a broad range of steels and common engineering materials when used within suitable cutting parameters.

How does the double-sided countersink improve performance?
A cylindrical hole with a double-sided countersink (40°–60°) secures the insert in the pocket and ensures repeatable clamping; this reduces movement at the cutting edge and helps the AH130 coated carbide deliver consistent cutting behaviour.

Can the insert be indexed to use multiple cutting edges?
Yes, the trigon form provides indexed edges where applicable. Proper seating and torque of the clamping screw within a compatible Tungaloy milling body allow multiple edge usage for cost-effective performance.

Which toolbody features must be checked before assembly?
The insert seat, geometry and cutter body must be technically matched to the WNGU form; incorrect matching can impair clamping stability and lead to suboptimal cutting results. Reference SKU TUN6987256 when verifying compatibility.

Is the AH130 grade suitable for interrupted cuts?
The AH130 grade is designed to be wear- and chipping-resistant, offering improved edge security in conditions that include interrupted cuts, provided machine setup and cutting data are appropriate.
