TPMT130308-PS AH6235 — ISO turning insert for turning applications (Tungaloy)

The TPMT130308-PS AH6235 is an ISO-standard triangular turning insert engineered for turning operations, especially suited to stainless steel and interrupted cuts.

• PVD-coated carbide for tough materials
• Optimised PS chipbreaker for interrupted cuts
• 11° clearance angle reduces cutting forces
• Triangular ISO insert with secure centre hole

Consistent cutting performance on stainless steel

The PVD-coated carbide grade AH6235 offers a balance of toughness and wear resistance that is tailored to the demands of stainless steel and applications with elevated breakout risk. As a tougher grade, AH6235 extends edge life under interrupted cutting and when machining work-hardened surfaces; this leads to fewer insert changes and increased uptime. The PVD layer supports adhesion resistance at elevated temperatures while preserving substrate integrity for dependable performance.

Exact fit and reliable clamping for process stability

Designed to the ISO form 130308, the insert ensures predictable interfacing with ISO holders when the correct form, relief, tolerance class, fastening and thickness are matched. The triangular geometry combined with a cylindrical hole plus single-side countersink (40°–60°) provides secure axial and radial locating, improving repeatability and minimising chatter. Clear specification of size, thickness and tolerance allows planners to standardise holders and reduce fixture variation across production runs.

Improved chip control and edge robustness

The integrated PS chipbreaker shapes chip flow for safer evacuation during turning, lowering the risk of entanglement in interrupted cuts. A 0.8 mm corner radius reinforces the cutting edge against mechanical shock while the 11° clearance angle reduces rubbing and lowers cutting forces; this combination helps maintain surface finish and tool life under variable engagement depths. Operators gain stable cutting behaviour and reduced risk of premature edge chipping.

System thinking for efficient tool management

The insert functions as part of an ISO turning insert system: compatible holders, underlays or clamp sets and replacement screws complete the assembly. Selection of the chipbreaker and grade should be based on workpiece material, machining mode and machine rigidity to maximise economy and process safety. Documentation of matching holder specifications and tolerance checks supports predictable changeovers and simplifies inventory management across batch and series production.

FAQ

What materials is this insert designed for?
The AH6235 grade is optimised for stainless steel and applications with increased breakout risk; the PVD-coated carbide substrate also performs across a wide range of steels when selected appropriately.

How does the PS chipbreaker benefit interrupted cuts?
The PS chipbreaker on the TPMT130308-PS AH6235 controls chip form and reduces chip snarling, which is particularly advantageous during interrupted cutting and variable engagement.

Which holder characteristics must be matched for correct use?
Compatibility requires matching form, relief (11°), tolerance class, fastening, size (13 mm) and thickness (3.18 mm); correct matching ensures secure clamping and repeatable results.

Can the insert be used for internal turning as well as external turning?
Yes, the ISO geometry and triangular form permit both external and internal turning when paired with the appropriate holder and toolpost configuration.

What indicates the difference of the AH6235 grade?
AH6235 is a tougher PVD-coated carbide grade offering enhanced edge resistance for stainless steel and applications prone to edge breakout, prioritising process security and tool life.
