TPMT110304-PS AH6225 — ISO triangle turning insert, PVD cemented carbide (Tungaloy)

A versatile ISO triangle turning insert, the TPMT110304-PS AH6225 is designed for external and internal turning operations, optimised for stainless steels and variable machining conditions

• PVD-coated cemented carbide grade AH6225
• Triangle ISO insert, 60° included angle
• 0.4 mm corner radius for versatile finishing
• Countersunk hole for secure clamping

Consistent edge performance for mixed machining conditions

The combination of a PVD-coated surface and cemented carbide substrate in grade AH6225 provides a balance between a sharp cutting edge and edge stability under changing cutting forces. This universal grade is engineered for machining stainless steels, where work-hardening and adhesive tendencies demand a resilient edge. The coating enhances wear resistance and reduces built-up edge, which in turn leads to longer tool life and a more predictable process window; tool changes and downtime are therefore reduced, supporting higher overall productivity.

Geometry engineered for surface quality and strength

The triangle ISO form with a 60° included angle offers three effective cutting corners per insert, while the 0.4 mm corner radius delivers a compromise between strength and surface finish — suitable for medium cutting depths and finishing passes. The 11° relief angle reduces rubbing and improves entry behaviour; this geometry supports consistent chip formation and contributes to improved part tolerances. Compatibility with holder geometry is determined by form, relief, tolerance class, clamp arrangement, size and thickness, so selection of the correct ISO holder ensures repeatable results.

Secure clamping and straightforward integration

A countersunk hole (cylindrical hole with single-sided countersink 40°–60°) provides reliable seating and easy clamping with standard screws and clamp sets. The insert fits into the typical ISO indexable turning system, comprising the insert, the appropriate external holder or boring bar, a seat/locking kit and replacement screws. Correct clamping prevents micro-movements at the cutting edge, which improves surface finish and extends usable life of the corner — an advantage in series production where repeatability matters.

Practical gains: process reliability and application guidance

Selecting the PS chipbreaker together with grade AH6225 is oriented towards controlled chips and adaptable performance across different stainless steels and machining stability levels. The engineering rationale is simple: stable chip control lowers the risk of workpiece damage and tool interruptions, while the PVD layer maintains a consistent cutting edge under intermittent conditions. If there is uncertainty about optimal feeds and speeds, technical advisors are available to provide cutting data and help match the insert to machine setup and material.

FAQ

Is this insert suitable for machining stainless steels?
Yes. The TPMT110304-PS AH6225 is a universal grade formulated for stainless steels, combining a PVD coating with a cemented carbide substrate to resist adhesion and maintain edge stability.

What is the function of the PS chipbreaker?
The PS chipbreaker promotes controlled chip formation and evacuation under variable cutting conditions, improving process reliability when using the AH6225 grade in turning applications.

Which holder features are required for correct compatibility?
Compatibility is determined by form, relief angle, tolerance class, attachment method, insert size and thickness; the TPMT110304-PS is intended for standard ISO turning holders designed for triangle inserts.

What cutting tasks suit the 0.4 mm corner radius?
A 0.4 mm corner radius is appropriate for medium finishing and light roughing, offering a balance between improved surface finish and edge strength.

Can the insert be used for internal turning or only external?
The insert is suitable for both external and internal turning when mounted in the appropriate external holder or boring bar within an ISO-compatible system.
