TPMT090208 AH6235 TPMT turning insert by Tungaloy — PVD-coated carbide, 60° triangular geometry

The TPMT090208 AH6235 is an ISO-format triangular turning insert for external and internal turning, designed for applications on rostfreier Stahl and for interrupted cuts where increased chip control is required

• ISO triangular insert TPMT 090208
• PVD-coated carbide grade AH6235
• Optimised for rostfreier Stahl and interrupted cuts
• 60° geometry with 0.8 mm corner radius
• Cylindrical hole with 40°–60° countersink

Productive turning with defined geometry for steady cycle times

The triangular 60° geometry combined with a 0.8 mm corner radius delivers a balance of strength and accessibility at the cutting edge, supporting repeatable toolpaths and predictable tool life. Because the insert is manufactured to ISO specifications, compatibility with a matching holder depends on form, relief angle, tolerance class, fixation and thickness; this standardisation simplifies tool selection and reduces setup time on the shop floor. The overall design is aimed at maintaining stable cutting conditions, which in turn helps to reduce scrap rates and keep machining cycles consistent.

Reliable performance on rostfreier Stahl and difficult interrupted cuts

The AH6235 grade is a PVD-coated carbide selected for tougher applications on rostfreier Stahl and for operations with elevated risk of edge breakout. The PVD coating enhances wear resistance and helps preserve the cutting edge temperature stability, while the substrate provides the toughness needed for interrupted cuts. For users unfamiliar with coatings: PVD (physical vapour deposition) forms a thin, hard layer that improves abrasion resistance without significantly altering the substrate’s fracture toughness, meaning longer usable life in many turning tasks.

Practical system integration and secure clamping for shop use

Integration into a turning system requires the correct matching of insert form, relief angle (11°), tolerance class and clamping style. The insert features a cylindrical hole with a one-sided countersink (40°–60°) for positive location and stable fixing in conventional external holders or boring bars. The plate thickness of 2.38 mm and the triangular format (size 09) make it suitable for both external and internal turning where access and rigidity permit. Clear compatibility reduces downtime and supports quick changeover in batch production.

Chip control, single-sided breaker and selection guidance

This insert is equipped with a single-sided chipbreaker, engineered to produce short, manageable chips in many rostfreier Stahl turning scenarios. Selecting the correct chipbreaker and grade depends on workpiece material, machining strategy and machine stability: the AH6235 grade is intended where a tougher substrate is required rather than the hardest possible coating, giving improved resistance to notch formation at the edge. Where chip control or surface finish is critical, pairing this insert with a suitable cutting parameter set and a rigid setup will yield the best outcomes.

FAQ

What types of turning operations suit this insert best?
The TPMT090208 AH6235 insert is intended for both external and internal turning, especially where interrupted cuts occur or when machining rostfreier Stahl with variable cutting conditions.

How does the AH6235 grade behave on rostfreier Stahl?
AH6235 is a tougher PVD-coated carbide grade designed to resist edge breakout and to provide stable wear behaviour when turning rostfreier Stahl, giving reliable tool life in demanding cuts.

Which holder characteristics are required for correct use?
A holder matching the ISO triangular form, the 11° relief angle, the plate thickness (2.38 mm) and the fixation style for a cylindrical hole with countersink is required to ensure secure clamping and repeatable positioning of the insert.

Can this insert produce a good surface finish?
With correct cutting data, machine rigidity and appropriate feed selection, the TPMT090208 AH6235 can deliver consistent surface quality; its chipbreaker and PVD coating help control chips and wear for steady finishes.
