ONMU 0507AN T3225 — indexable insert for milling by Tungaloy

The ONMU 0507AN T3225 is an octagonal carbide indexable insert engineered for milling operations within Tungaloy milling systems, designed to match the seat, geometry and cutter body for secure and repeatable performance.

• T3225 wear-resistant carbide grade
• Octagonal 05 insert format
• 135° approach angle for stable cutting
• Cylindrical hole with 40°–60° countersink

Engineered for stable, repeatable milling performance

The octagonal form and the 135° approach geometry deliver a balance between cutting stability and insert indexability. The octagonal shape provides multiple index positions, reducing downtime for reorientation and improving process uptime. The 135° angle helps to distribute cutting forces across the tool body, which reduces tool deflection in shoulder and contour milling. Constructed from a carbide substrate and finished in the Tungaloy T3225 grade, the insert is optimised for a combination of wear resistance and edge toughness, making it suitable for a wide range of milling tasks where consistent performance matters. The design supports planing, shoulder, slot, high-feed and contour milling when combined with the appropriate cutter family.

Consistent chip control and edge stability for economical machining

A double-sided chipbreaker design on this insert promotes predictable chip formation and evacuation, which contributes to surface finish consistency and reduced risk of built-up edge. The T3225 grade complements the geometry by providing stable edge behaviour under varying cutting conditions, which translates into longer effective tool life and fewer index changes. The octagonal format and double-sided breaker mean more usable edges per insert, enhancing economy per cutting edge. With the insert’s cylindrical hole with countersink, clamping force is evenly transmitted, ensuring that the cutting edge maintains its intended angle and position during interrupted cuts or higher machining forces.

Practical compatibility and handling for shop-floor use

The insert’s dimensions — size 05 and a plate thickness of 7.94 mm — plus the zero corner radius make it straightforward to integrate into matching Tungaloy cutter bodies; the seat, geometry and cutter body must coincide technically for safe use. The cylindrical hole with double-sided countersink (40°–60°) secures the insert and facilitates precise repeatability when indexing. Marked as suitable for milling applications, the part is supplied as a single octagonal plate that is intended for use within the Tungaloy modular system where the clamping screw and any required backing pads are matched to the insert form. Specification transparency supports process planning: the insert is a component engineered to provide reliable edge life and predictable behaviour rather than a universal substitute for incompatible holders.

FAQ

What materials is this insert suitable for?
The T3225 grade of the insert is designed for a broad range of materials in milling applications; the ONMU 0507AN T3225 plate provides a compromise of wear resistance and toughness suitable for general steel and mixed-material operations when paired with the correct cutter body.

How does the octagonal shape affect tooling economy?
The octagonal form increases the number of indexing positions per insert, so overall usable edges are maximised; this helps to improve economy per edge and reduces the frequency of insert changes.

Why is the cylindrical hole with countersink important?
A cylindrical hole with double-sided countersink ensures secure mechanical seating and even clamping force transfer, which maintains consistent cutting geometry and reduces the risk of movement during interrupted cuts.

Is this insert compatible with non-Tungaloy cutter bodies?
Compatibility requires that seat geometry, clamping method and plate dimensions match; the insert is intended for Tungaloy milling systems, so only holders with matching dimensions and clamping characteristics should be used.

What benefits does the T3225 grade provide?
The T3225 grade balances wear resistance and edge stability, offering a reliable compromise between life and toughness for a variety of milling tasks where consistent edge behaviour is required.
