TPMT090204 AT9530 Tungaloy indexable insert — triangular ISO insert for turning applications

The TPMT090204 is an ISO triangular indexable insert engineered for finishing and light turning of steel, optimised for excellent surface quality and even tool life.

• ISO triangular insert TPMT form
• Coated cermet AT9530 for fine finishing
• 0.4 mm corner radius for high surface finish
• Countersunk central hole for secure fastening

Predictable finishing and consistent surface quality

The insert is built around a coated cermet grade that emphasises consistent flank wear and surface integrity during finishing passes. Its geometry provides a 0.4 mm corner radius that reduces chatter and helps maintain an even contact footprint, which in turn supports a superior surface finish on steel components. The combination of geometry and substrate makes the insert particularly suitable for light to finishing cuts where dimensional accuracy and visual quality are primary objectives.

Compatibility and safe clamping for production environments

Compliance with ISO 090204 geometry ensures the insert matches a wide range of standard holders when the form, 11° clearance angle, tolerance class, fastening and thickness are observed. The central cylindrical hole with a one-sided countersink (40°–60°) gives secure, repeatable clamping and simplifies index changes in automated or manual toolholders. For workshop planning, note the 2.38 mm thickness and triangular profile when specifying holders or shims to guarantee correct seat and clamping force.

Practical advantages in chip control and process stability

A one-sided chipbreaker combined with the coated cermet substrate assists in producing regular chip segments during light turning tasks, reducing the risk of long, entangling chips and improving operator safety and machine uptime. The insert’s design supports stable cutting conditions at finishing feeds and speeds, which helps to extend component batch consistency and reduces the need for repeated rework.

Material focus and recommended uses

This indexable solution is intended primarily for machining steel, with the cutting data and chipbreaker selection tuned for finishing and light machining operations. The coating and substrate balance wear resistance with toughness to withstand the thermal and mechanical cycles typical of finishing passes, helping to secure productivity when high surface quality and repeatable tool life are required.

System perspective and process integration

The insert is supplied as part of a system consisting of the ISO indexable plate, a matching external holder or boring bar, a shim/clamping set and replacement screws. Correct system assembly—selecting the appropriate holder geometry and tolerance class—ensures the AT9530 coating and carbide substrate perform as intended, translating material properties into stable, reproducible process results on the shop floor.
