TNMU 1207R2 AH3135 indexable insert for milling — Tungaloy

The TNMU 1207R2 AH3135 is a triangular indexable insert designed for face, shoulder, slot, high-feed and contour milling in compatible Tungaloy cutter bodies.

• PVD-coated carbide AH3135 for longevity
• Wear- and fracture-resistant cutting grade
• Triangular 12 mm insert, 60° geometry
• Cylindrical hole with double countersink

Consistent production performance with a focus on cutting efficiency

The TNMU1207R2 insert delivers predictable results through a combination of a wear-resistant PVD-coated carbide grade and a geometry optimised for secure seating. The AH3135 grade is tuned to maintain a sharp cutting edge under mixed milling conditions, which reduces unplanned tool changes and supports a stable process. This leads to improved chip evacuation and steady component quality, helping to keep cycle times low and productivity high.

Secure clamping and geometry that reduce breakouts

A triangular form with a 60° geometry provides three usable cutting edges per indexable insert and a compact contact zone that enhances clamping stability. The insert’s cylindrical hole with double-sided countersink (40°–60°) ensures repeatable seating and torque distribution when paired with the matching clamping screw and cutter body. The double-sided chipbreaker aids chip control on both orientations, while the 7.94 mm thickness contributes to rigidity during higher feed operations, lowering the risk of edge breakout.

AH3135 grade and PVD coating explained for process reliability

The AH3135 designation denotes a PVD-coated cemented carbide designed for fracture and wear resistance in milling. The PVD coating forms a thin, hard layer that improves flank wear resistance and reduces adhesion at the cutting face; in practice this means longer cutting edge life and more consistent surface finish across a production run. For operators unfamiliar with coatings, PVD stands for physical vapour deposition — a production-grade technique that adheres a durable layer without compromising substrate toughness.

System compatibility and recommended applications

These inserts are part of a system comprising cutter body, indexable insert, clamping screw and, where required, a locating pad; correct matching of seat and geometry is essential for full performance. Typical applications include planing, shoulder milling, slotting, contouring and high-feed operations depending on the chosen milling family. For new tool setups, select the cutter body that matches the insert seat and ensure the clamping torque and runout are within machine manufacturer recommendations to preserve process security and maximise tool life.

FAQ

What milling tasks is this insert intended for?
The insert is intended for a range of milling operations including face, shoulder, slot, high-feed and contour milling when used in compatible Tungaloy cutter systems.

How does the AH3135 grade improve tool life?
The AH3135 grade combines a tough cemented carbide substrate with a PVD coating, enhancing wear resistance and reducing the risk of edge chipping during interrupted or heavy milling.

Why is the cylindrical hole with double countersink important?
The cylindrical hole with double countersink provides reliable seating and even clamping force distribution, which supports repeatable positioning and reduces the likelihood of insert movement under load.

Is the insert reversible and how many cutting edges are available?
The triangular form offers three indexable cutting edges per insert; the double-sided chipbreaker allows productive use on both orientations.

How should the insert be integrated into an existing milling system?
Ensure the insert seat, geometry and clamping method of the cutter body match the insert specifications; correct torque and runout control are essential for achieving the advertised process security.
