TPMT16T304-PM AH6235 – TPMT ISO 16T304 turning insert by Tungaloy, PVD-coated carbide for turning

The TPMT16T304-PM AH6235 is an ISO-standard triangular turning insert designed for external and internal turning operations, particularly suited to interrupted cuts and machining of stainless steel.

• PVD-coated carbide grade AH6235
• Triangular ISO indexable insert, 60° geometry
• 0.4 mm nose radius for fine finishing
• Suitable for stainless steel and interrupted cuts

Durable carbide grade for stable chip control and longer tool life

The combination of a PVD-coated surface and the tougher AH6235 grade delivers improved resistance to chipping and abrasion when machining demanding materials. This makes the insert particularly effective in avoiding premature edge failure during interrupted cuts and in workpieces that tend to work-harden. The result is higher process reliability and fewer tool changes, which supports uninterrupted production runs and reduces overall cycle costs.

Geometry tuned for rigidity and surface quality

The 60° triangular geometry with an 11° clearance and a 0.4 mm nose radius balances cutting strength with surface finish. The modest nose radius permits precise finishing without excessive cutting forces, while the acute geometry provides rigidity for external and internal turning. For operators less familiar with the specifics, a nose radius defines the contact area: a smaller radius reduces cutting load peaks and helps achieve a consistent surface without excessive vibration.

Standardised fit and secure clamping for quick integration

Designed as part of an ISO indexable system, the insert integrates with holders and boring bars that match form, clearance angle, tolerance class, fastening and thickness. The plate is supplied with a cylindrical hole plus a single-sided countersink (40°–60°) for positive locating and secure clamping; its thickness of 3.97 mm and 16 mm inscribed size follow ISO norms to simplify replacement. This compatibility reduces setup time and simplifies inventory management across multiple machines.

Productivity advantages through focused chipbreaking and application fit

The PM chipbreaker and the selected grade optimise chip formation for stainless steels and similar materials, reducing the risk of built-up edge and facilitating chip evacuation. By pairing the insert with an appropriate holder and cutting parameters, workshops can expect consistent surface quality and extended edge life, contributing to lower per-part tooling costs and more predictable maintenance intervals. The insert’s design supports fast insertion changes and repeatable results across batches.

FAQ

What materials is this insert suited for?
The TPMT16T304-PM AH6235 insert is optimised for machining stainless steel and applications with interrupted cuts; the AH6235 grade provides toughness that helps prevent chipping.

How does the PM chipbreaker affect performance?
The PM chipbreaker promotes controlled chip formation and evacuation when machining ductile materials, improving surface quality and reducing the risk of built-up edge on the insert.

Is this insert compatible with existing ISO holders?
Yes, the insert conforms to ISO dimensions and clamping features; compatibility depends on holder form, clearance angle, tolerance class, fastening type, size and thickness.

What is the recommended approach for minimising edge wear?
Use the PVD-coated AH6235 grade with conservative cutting data for initial trials, ensure stable clamping and evaluate coolant and feed; this approach reduces mechanical and thermal loading at the cutting edge.

Can the insert be used for finishing passes?
With a 0.4 mm nose radius, the insert can achieve good finishing results provided cutting parameters and machine rigidity are suitable.
