TPGA 090204 TH10 turning insert by Tungaloy — ISO triangular indexable insert for turning

The TPGA 090204 TH10 is an ISO-standard triangular indexable insert designed for external and internal turning, optimised for non-ferrous materials and applications that benefit from a sharp, uncoated cutting edge

• TPGA 090204 insert, ISO triangular form
• Uncoated carbide grade TH10 for non-ferrous
• 0.4 mm corner radius for fine finishing
• 11° clearance angle, cylindrical centre hole

Precise, low-force cutting for clean surface results

The triangular indexable insert is manufactured from uncoated carbide in the TH10 grade, a sharp universal composition that helps to reduce cutting forces and supports cleaner surface finishes when machining non-ferrous materials. The absence of a coating means the cutting edge runs cooler under low-to-moderate cutting speeds and produces less built-up edge on softer alloys; this can translate into fewer machine stops for rework and consistent part quality. Compatibility with toolholders is determined by the insert’s form, 11° clearance, tolerance class, clamping method, size and thickness, so correct holder selection ensures repeatable performance and process stability.

Small corner radius and secure clamping improve finish and tool life

With a 0.4 mm corner radius and a plate thickness of 2.38 mm, the insert supports delicate finishing passes and dimensional control in tight-tolerance turning. The cylindrical centre hole provides secure clamping in standard ISO triangular pockets, reducing micro-movements that can degrade surface quality. Supplied without a chipbreaker, the insert allows flexibility: select a chip control geometry and cutting parameters matched to the workpiece material and machining conditions to balance chip evacuation and edge life. These design choices contribute to efficient, low-vibration cutting and predictable tool-change intervals.

System approach and practical workshop advantages

This insert is part of an ISO system comprising the insert itself, a suitable external holder or boring bar, an underlay/clamp set and spare screws; this modular approach simplifies inventory and replacement. The TPGA 090204 format supports both external and internal turning operations across a broad range of non-ferrous alloys, enabling fast index changes and minimal set-up time. For workshop planning, the clear dimensional data and ISO conformity support straightforward toolholder matching and process documentation, helping to keep machining schedules tight and scrap rates low.

FAQ

What materials is this insert best suited for?
The TPGA 090204 TH10 insert is optimised for non-ferrous materials; the TH10 uncoated carbide grade supports low cutting forces and clean surfaces when machining aluminium, brass and similar alloys.

Is the insert supplied with a chipbreaker?
No, the insert is supplied without a chipbreaker; select an appropriate chip control geometry and holder to suit the workpiece material and machining stability.

How is compatibility with toolholders ensured?
Compatibility depends on the insert’s form, 11° clearance, tolerance class, clamping arrangement, size and thickness; matching these parameters with a standard ISO triangular holder ensures secure clamping and correct seating.

Can this insert be used for internal turning?
Yes, the insert’s triangular shape and ISO conformity make it suitable for both external and internal turning when paired with the correct boring bar or toolholder.

What advantages does the uncoated TH10 grade provide?
The TH10 uncoated grade offers a sharp cutting edge that reduces cutting forces and minimises built-up edge on softer alloys, supporting improved surface finish and predictable tool behaviour.
