TPMT 16T304 AH6235 Turning Insert (PVD carbide, 0.4 mm radius) – Tungaloy

A TPMT16T304-PS AH6235 ISO turning insert designed for reliable external and internal turning, optimised for stainless-steel work and interrupted cutting conditions

• PVD-coated carbide grade AH6235 for stainless steel
• Triangular insert, 60° cutting angle, 0.4 mm radius
• 11° clearance angle and 3.97 mm plate thickness
• Central hole with cylindrical bore and countersink

High process stability for stainless-steel turning

The AH6235 grade is a PVD-coated carbide chosen for its toughness and resistance to edge breakage when machining stainless steels and interrupted surfaces. This combination reduces the risk of flank chipping under unstable cutting conditions; improved edge integrity results in fewer tool changes and a steadier production flow. The PS chipbreaker helps control chip formation during moderate to heavy cuts, supporting consistent surface quality and repeatable machining results.

Geometry that supports precision and rigidity

A triangular plate with a 60° included angle and a 0.4 mm corner radius provides a balance between strength and finish. The acute geometry concentrates cutting forces through a robust corner, while the minor radius still enables acceptable corner strength for finishing passes. The 11° relief angle and a plate thickness of 3.97 mm increase bending stiffness when mounted in a suitable ISO holder, improving dimensional accuracy and reducing tool deflection on long overhangs or heavy cuts.

ISO compatibility and secure clamping for predictable performance

Produced to ISO dimensions, the insert interfaces with holders according to form, clearance angle, tolerance class, fastening method, size and thickness. The central hole — a cylindrical bore with a single-sided countersink (40°–60°) — ensures reliable seating and repeatable clamping. Selection of a matched carrier and correct torque on the clamping screw prevent slippage and maintain repeatability across indexings, which is essential for automated or batch production where tool-change consistency affects throughput.

Practical guidance for selection and operation

For applications involving frequent interruptions or built-up edge tendencies typical of stainless steels, the AH6235 grade combined with the PS chipbreaker provides a compromise between tool life and edge security. The triangular shape allows three usable cutting edges per index, improving economy in batch operations. When integrating the insert into a toolholder, check compatibility with ISO holder geometries and observe manufacturer-recommended cutting data to maximise tool life and surface finish.

FAQ

What materials is this insert suited for?
The AH6235 grade with PVD coating is intended primarily for stainless steel machining and is especially resilient in interrupted cut conditions.

How is the insert secured in the toolholder?
The plate uses a central cylindrical hole with a single-sided countersink; secure seating and correct clamping torque ensure repeatable positioning when used with compatible ISO holders.

What is the benefit of the 0.4 mm corner radius?
A 0.4 mm radius offers a compromise between corner strength and surface finish, reducing susceptibility to chipping while enabling reasonably fine profiles.

How many cutting edges are available per index on this geometry?
The triangular shape provides three primary cutting edges per insert index, improving economy for cyclic or batch operations.

Which chipbreaker is fitted and what effect does it have?
The PS chipbreaker is designed to promote controlled chip formation under a range of cutting conditions, aiding evacuation and improving surface quality.
