TPMT 090208 AH6225 indexable insert for turning — Tungaloy

TPMT 090208 AH6225 is an ISO‑normed triangular indexable insert designed for general turning applications, optimised for stainless steel machining.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel turning
• ISO‑compliant triangular insert 09
• 11° clearance, 0.8 mm corner radius

Consistent chip control with a sharp, durable cutting edge

The TPMT090208 AH6225 insert combines a PVD-coated surface with a high-performance carbide substrate to deliver dependable edge stability during medium turning operations. The AH6225 grade is formulated for stainless steel, providing a balance between a sharp cutting edge and resistance to wear; this reduces built-up edge and helps maintain surface finish under varying conditions. Explaining briefly: the PVD layer lowers adhesion and improves heat resistance, while the carbide core supports mechanical strength — together enabling longer indices between changes and fewer process interruptions.

ISO compatibility for rapid toolset integration

The triangular design is ISO‑compliant, which simplifies holder selection and reduces setup time. Key dimensional features include a triangular insert size 09, 2.38 mm thickness, and an integrated 0.8 mm corner radius, matched to common ISO tooling systems. Compatibility with a holder depends on shape, clearance and tolerance class as well as size and thickness; choosing the correct holder and clamp ensures stable clamping forces and repeatable positioning. This interchangeability supports lean production and makes stocking and replenishment more efficient.

Practical advantages in internal and external turning

Designed for both external and internal turning, the insert features a one-sided chipbreaker and a cylindrical hole with single-side countersink (40°–60°), facilitating secure mounting and predictable chip formation. The 11° clearance contributes to controlled cutting forces and reduces rubbing on the flank, which helps preserve workpiece geometry and extends insert life. For workshop planners, the combination of universal grade and standard geometry means fewer special inserts are needed, which improves process reliability and overall machining economy.

FAQ

Which materials is this insert suited for?
The AH6225 grade is a universal PVD-coated carbide designed primarily for stainless steel machining; it performs well under medium cutting conditions and varying workpiece properties.

Is the insert compatible with standard ISO holders?
Yes; the insert follows ISO geometry conventions — compatibility depends on matching form, clearance angle, tolerance class, fastening method, size and thickness to the chosen holder.

What are the key geometry values to check before mounting?
Check the 0.8 mm corner radius, 11° clearance, 2.38 mm thickness and the triangular 09 size to ensure correct fit and performance.

How is the insert secured in the holder?
The insert features a cylindrical hole with single-side countersink (40°–60°) for screw fastening; this provides secure clamping and precise positioning for repeatable turning operations.

Can this insert be used for internal turning?
Yes; the geometry and chip control features make it suitable for both external and internal turning tasks when paired with an appropriate holder and tooling setup.
