ONMU0705AN T1215 octagonal carbide indexable insert for milling (with hole, 135°)

The ONMU0705AN T1215 is a carbide indexable insert engineered for high-productivity milling in Tungaloy milling systems, suitable for face, shoulder, slot, high-feed and contour milling depending on the assigned cutter family

• T1215 grade carbide for general milling
• Octagonal 07 size, 5.56 mm thickness
• Cylindrical hole with 40°–60° double countersink
• Double-sided chipbreaker for versatile cutting

Engineered grade for balanced wear resistance and toughness

The T1215 cutting grade is designed to provide a balanced blend of wear resistance and toughness, which translates into predictable edge life under varied milling conditions. As a result, tool change intervals can be planned with greater certainty and part quality is maintained across batches. The insert’s carbide composition delivers the hardness required for abrasive workloads while retaining enough resistance to chipping during interrupted cuts. This combination is particularly advantageous in production environments where a mix of facing, slotting and contour operations is performed and consistent results are essential.

Mechanical design that secures clamping and cutting stability

An octagonal form with a 135° included angle and a 0° clearance yields a compact geometry that distributes cutting forces evenly across the tool body. The insert is supplied with a cylindrical hole and a double-sided countersink (40°–60°) to ensure reliable seating and repeatable clamping torque in suitably matched toolholders. At 5.56 mm thickness and size 07, the component offers a robust contact area for high-feed and shoulder milling tasks, while the double-sided chipbreaker supports controlled chip formation and an improved surface finish. It is important to match the insert seat, geometry and milling body technically to guarantee correct function.

Application scope, selection guidance and process benefits

Placed within Tungaloy’s insert system, this indexable geometry is intended for a wide range of milling applications; the system architecture comprises a milling body, indexable insert, clamp screw and, where required, backing shim. The insert is compatible only with tool bodies that accept the ONMU0705AN geometry and hole style, so component interchangeability must be verified before use. When paired with the correct cutter, the insert improves productivity through stable cutting edges and optimised chip control, thereby reducing downtime and enabling smoother cycle planning.

FAQ

What milling operations is this insert suitable for?

The ONMU0705AN T1215 indexable insert is intended for face, shoulder, slot, high-feed and contour milling depending on the assigned cutter family within the Tungaloy milling system.

Does the insert fit non-Tungaloy tool bodies?

The insert requires a matching seat and geometry; compatibility is ensured when the toolholder is specified for the ONMU0705AN geometry and clamping style.

What advantages does the T1215 grade offer?

The T1215 grade provides a balance of wear resistance and toughness, delivering stable cutting edges and predictable tool life for mixed milling applications.

How does the hole and countersink affect performance?

The cylindrical hole with a double-sided countersink (40°–60°) ensures secure seating and repeatable clamping, which improves repeatability and reduces the risk of insert movement under load.

What is the corner radius and why does it matter?

This insert has a corner radius of 0 mm; a zero radius is chosen where sharper profiles or finer detail are required and where specific cutting edge geometry benefits the operation.
