TPMT 130304 AH6235 — TPMT130304-PSS turning insert for Drehen (PVD-coated carbide, 0.4 mm radius) — Tungaloy

A TPMT130304-PSS AH6235 indexable turning insert engineered for reliable external and internal turning, especially where stainless steels and interrupted cuts present elevated chipping risk.

• PVD-coated carbide grade AH6235
• Optimised PSS chipbreaker for steels
• 0.4 mm corner radius for precise finishing

Improved process reliability through a tougher grade

The AH6235 grade is a PVD-coated carbide formulated to combine toughness with wear resistance, specifically for applications involving rostfreie Stähle and interrupted cuts. A tougher substrate reduces edge chipping in unstable cutting conditions, which leads to fewer tool changes and more consistent cycle times. PVD (physical vapour deposition) is a thin-film coating applied to the cutting edge to improve resistance to adhesion and high-temperature wear; in practice, this means longer effective edge life under demanding turning operations.

Geometry and chip control for consistent surface quality

The triangular plate with a 60° included angle and a 0.4 mm corner radius delivers a controlled engagement with the workpiece, balancing strength and finishing capability. The PSS chipbreaker is optimised for steel machining and supports predictable chip flow under a range of cutting parameters. The insert’s 11° clearance contributes to reduced rubbing and improved surface finish. Compatibility with a holder is determined by form, clearance angle, tolerance class, fastening, size and thickness; this ensures that the insert is correctly seated and clamped, which is essential for repeatable results and tool life.

System benefits and practical workshop use

The insert is supplied as an ISO-standard turning plate and forms part of a system that includes a matching external holder or boring bar, a pad/clamping set and replacement screws. This modular approach allows rapid changeover and minimises downtime. For choice of chipbreaker and grade, match the PSS geometry and AH6235 toughness to the workpiece material, cutting strategy and machine stability to achieve productive machining. The combination of controlled chip formation and robust substrate provides confidence in everyday production, reducing scrap and stabilising output quality.

FAQ

Which materials are best machined with this insert?
The TPMT130304-PSS AH6235 insert from Tungaloy is optimised for rostfreie Stähle (stainless steels) and performs well in interrupted cutting where chipping risk is higher.

What effect does the 0.4 mm corner radius have?
A 0.4 mm radius balances strength at the cutting edge with the ability to achieve a fine surface finish; it reduces edge stress compared with very small radii while still permitting accurate contouring.

How is compatibility with a toolholder ensured?
Compatibility is determined by the insert form, the 11° clearance angle, tolerance class, fastening type, size and thickness; proper matching to the holder secures repeatable seating and clamping.

What mounting features does the insert have?
The plate is supplied with a cylindrical hole and a single-sided countersink (40°–60°), suitable for standard clamping systems and replacement screws as used in ISO insert assemblies.

Is the coating suitable for high-temperature turning?
The PVD coating on the AH6235 grade enhances resistance to adhesion and thermal wear, improving edge life under elevated cutting temperatures encountered with stainless steels.
