TPMT 16T308 AH6225 triangular ISO turning insert, PVD-coated carbide for turning (Tungaloy)

The TPMT16T308-PM AH6225 is an ISO-format triangular indexable insert engineered for external and internal turning, offering a medium-duty cutting solution optimised for variable machining conditions.

• ISO triangular insert TPMT 16T308 AH6225
• PVD-coated carbide for stainless steels
• Sharp yet stable cutting edge, medium duty
• Cylindrical hole with 40°–60° countersink

Reliable machining performance for turning operations

The PVD-coated, cemented carbide grade AH6225 delivers a consistent balance between wear resistance and edge toughness, which is particularly valuable when working with stainless steels. The coating reduces flank and crater wear, extending tool life under fluctuating cutting conditions. The insert's geometry yields a controlled cutting action that helps maintain component dimensional stability, so operators can expect repeatable results across batches and reduced frequency of insert changes.

Secure mounting and ISO compliance for fast tool changes

Compatibility with ISO-certified holders is a core design consideration; the triangular plate features a cylindrical centre hole with a single-side countersink (40°–60°) for secure clamping and accurate seating. This arrangement simplifies assembly on standard external holders or boring bars and reduces set-up time. The standardised form and tolerance class ensure interchangeability within ISO tool systems, supporting efficient workshop logistics and minimising downtimes caused by bespoke clamping solutions.

Balanced chip control and edge life for mixed conditions

The PM chipbreaker profile provides consistent chip control during both external and internal turning, reducing the likelihood of entangling or long stringy chips in interrupted cuts. The combination of a 0.8 mm corner radius and the insert’s medium-duty geometry gives a compromise between edge strength and surface finish: the edge resists chipping while still delivering acceptable surface quality on most turned parts. For workshop managers, this means fewer rejects and more predictable insert consumption.

Versatility across stainless-steel turning tasks

Designed as a universal grade for stainless steels, the insert supports a wide range of turning strategies—from light finishing to moderate roughing—by choosing appropriate feeds and speeds for the material and machine stability. The 3.97 mm plate thickness and the 60° included angle assist in distributing cutting forces, which improves stability on less rigid set-ups. When working with variable workpiece geometries or interrupted cuts, this insert provides a practical compromise between performance and robustness.

FAQ

What applications is this insert designed for?
The TPMT16T308-PM AH6225 insert is designed primarily for external and internal turning operations and is optimised for machining stainless steels under medium-duty conditions.

Is the insert compatible with standard ISO toolholders?
Yes. The insert follows ISO geometry and seating tolerances; the cylindrical centre hole with single-side countersink ensures secure clamping in ISO-compatible holders.

What does the PM chipbreaker provide?
The PM chipbreaker on this Tungaloy turning insert improves chip control for a range of cutting conditions, helping to avoid long, stringy chips and facilitating safe, continuous turning.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius provides a compromise between a robust cutting edge and surface finish, offering improved resistance to chipping while still allowing acceptable part quality on most turning tasks.

Which material types is the insert best suited to?
The PVD-coated carbide grade AH6225 is formulated as a universal choice for stainless steels, providing wear resistance and edge stability across variable stainless-material compositions.
