TPMT 130304 T9225 — ISO triangular turning insert for Turning, CVD-coated carbide, 0.4 mm radius (Tungaloy)

TPMT130304-24 T9225 is an ISO-format triangular turning insert engineered for external and internal turning operations where interrupted or variable engagement requires enhanced toughness and secure clamping.

• TPMT 130304 geometry, ISO standard
• CVD-coated carbide grade T9225
• 0.4 mm corner radius for stable cuts
• Cylindrical hole with 40°–60° countersink

Consistent performance on medium–heavy steel

The T9225 grade is a CVD-coated carbide developed as a robust universal solution for the medium–heavy steel sector. Its microstructure balances hardness and toughness to tolerate changing engagement conditions and light interruptions without premature chipping. The modest 0.4 mm corner radius helps to distribute cutting forces, reducing the risk of edge fracture and delivering predictable tool life under tougher feeds. For applications requiring controlled chip formation, the chipbreaker 24 promotes manageable chip shapes and safer evacuation.

Secure seating and repeatable clamping for production use

Compatibility with tools is determined by form, relief, tolerance class, fastening, size and thickness; the ISO format of this triangular insert ensures straightforward integration with standard holders when those parameters match. The 11° relief angle and 3.18 mm thickness provide stable support in the pocket, while the triangular shape and cylindrical hole with a single-sided countersink (40°–60°) enable positive location and reliable clamping. This design reduces movement in the seat and makes index changes quick and repeatable, supporting uninterrupted production cycles.

Longer tool life and process stability through coating and system design

A CVD finish on cemented carbide improves abrasion resistance and thermal stability, which in practice means longer intervals between index changes and consistent workpiece finish across batches. When combined with a matched holder or boring bar and the correct shim/clamping set, the insert forms part of a compact system that is easily serviced with spare screws and replacement inserts. The result is reduced machine downtime, predictable maintenance intervals and improved throughput for shopfloors handling mixed-part production.

Practical selection guidance for reliable turning

This insert is intended for external and internal turning and is especially suitable where interrupted cuts or variable engagement occur. Select the chipbreaker 24 and the T9225 grade when the workpiece material and machining stability demand higher toughness. For fine finishing or very soft materials, consider alternative radii or grades; for heavy roughing, the universal nature of this insert will still offer good wear resistance and edge security. Confirm holder compatibility before ordering to ensure optimal performance.

FAQ

What workpiece materials is this insert suited for?
The TPMT130304-24 T9225 insert is specified for medium–heavy steel machining; the T9225 grade and CVD coating give a balance of toughness and wear resistance suitable for steels and operations with variable engagement.

How does the 0.4 mm corner radius affect cutting?
A 0.4 mm corner radius increases edge strength and reduces the likelihood of chipping under interrupted cuts, which helps the insert deliver more consistent tool life when roughing or semi-finishing.

Is special tooling required to use this ISO insert?
No special tooling is required, but correct matching of holder geometry is essential; the insert must be used with a compatible external holder or boring bar and the proper shim/clamping set to ensure secure seating and repeatable results.

What role does chipbreaker 24 play in machining?
The chipbreaker 24 is designed to control chip form for safer evacuation and improved surface quality; it is particularly useful when machining longer chips or when machining parameters vary.

Can this insert handle interrupted cuts?
Yes, the combination of the T9225 grade and the insert geometry makes it suitable for interrupted cuts, offering enhanced toughness to withstand changing engagement conditions.
