ONMU 0507AN T1215 indexable milling insert for milling — Tungaloy

The ONMU0507AN T1215 is an octagonal indexable insert designed for milling applications in Tungaloy milling systems, providing a balance of wear resistance and edge stability for repeated indexing.

• Octagonal insert, 05 size, 135° cutting angle
• Tungaloy T1215 grade for wear resistance
• 7.94 mm plate thickness for robust clamping
• Central hole with double-sided countersink (40°–60°)

Durable carbide grade for consistent tool life

The T1215 chemistry, supplied by Tungaloy and manufactured as a carbide cutting grade, is formulated to deliver a predictably long life in milling operations. Its composition supports a balance between wear resistance and toughness, meaning the cutting edge retains integrity during interrupted cuts and moderate mechanical loads. Specifying this grade helps to reduce unplanned tool changes and maintain steady production throughput while preserving component surface quality.

Geometry and clamping designed for process security

The octagonal plate shape and precise dimensions are engineered to match compatible milling bodies; the octagonal design enables multiple indexings while the 7.94 mm plate thickness contributes to a secure seat and reduced vibration. The insert is supplied with a central hole and a cylindrical hole style plus a double-sided countersink (40°–60°) to ensure correct orientation and reliable clamp engagement. These geometric features are critical for repeatable positioning and safe toolholding during high-feed or heavy-duty passes.

Versatility across common milling operations

This insert is intended for a range of milling tasks including face milling, shoulder machining, slotting, high-feed operations and contour milling, depending on the assigned tool family. The product complements the chosen geometry of the cutterbody: insert shape, seat and screw must be technically compatible to achieve the stated performance. Using a grade tuned for milling simplifies process selection for mixed production runs and supports consistent component tolerances.

Controlled chip formation and stable cutting edge

Equipped with a double-sided chipbreaker, the insert promotes controlled chip segmentation and evacuation across both cutting directions, which helps to avoid built-up edge and prolong the effective edge life. The combination of chip control geometry and a robust grade reduces thermal and mechanical load on the cutting zone, enabling longer periods between indexings and fewer tool interventions, which supports efficient cycle planning.

Practical benefits for production planners

From a planning perspective, the octagonal insert form and indexable design translate into economical edge usage and simplified inventory management: multiple usable edges per insert reduce replacement frequency, and the standardised ISO designation supports quick identification in procurement. When integrated into a compatible Tungaloy milling system, the component contributes to predictable productivity and higher machine uptime, making it a practical choice for shops seeking reproducible results.

FAQ

What milling operations is this insert suitable for?
The ONMU0507AN T1215 insert is suitable for face milling, shoulder milling, slotting, high-feed and contour milling when used in the corresponding Tungaloy cutter family.

How does the T1215 grade affect performance?
The T1215 grade offers a balance of wear resistance and toughness; in ONMU0507AN it supports edge stability and consistent wear behaviour under typical milling loads.

Is the insert compatible with other manufacturers' milling bodies?
Compatibility requires matching the insert seat, geometry and clamping method; the ONMU0507AN designation indicates the intended geometry but only the correct cutter body will ensure safe clamping.

What does the octagonal shape mean for tool life?
An octagonal form provides multiple indexable edges, effectively increasing the number of usable cutting edges per insert and lowering replacement frequency.

What clamping features must the toolholder provide?
The cutter must accept the ONMU0507AN plate seat and secure the plate via the central hole and corresponding clamping screw, compatible with the cylindrical hole and double-sided countersink.
