TCMT110308 AH6225 turning insert — Tungaloy

A TCMT110308 AH6225 indexable turning insert for external and internal turning, engineered for reliable performance on stainless steels.

• PVD-coated carbide grade AH6225
• Designed for stainless steel machining
• 60° triangular form for versatile turning
• 0.8 mm corner radius for robust edges

Consistent cutting performance for stainless steels

The combination of a PVD-coated surface and a modern cemented carbide substrate offers a balance between a sharp cutting edge and sufficient toughness for mixed cutting conditions. This results in consistent chip formation and reduces the risk of built-up edge when machining stainless steels, which improves component quality and reduces rework. The insert’s geometry supports repeatable results in medium-duty turning, making it suited to batch production and varied stainless grades.

Secure clamping and ISO compatibility for flexible use

As an ISO triangular insert with a 60° included angle, compatibility with a wide range of toolholders is ensured when the holder matches form, clearance, tolerance class, clamping and thickness. The presence of a hole with a cylindrical bore and single-side countersink enhances secure locating and repeatable seating, which translates into stable cutting conditions and predictable tool life under correct clamping. This helps maintain process reliability across different setups.

Optimised chip control for stable surface finish

The one-sided chipbreaker is designed to control chip flow for common turning tasks, promoting continuous chips and preventing entanglement in many stainless steel applications. Improved chip control reduces manual intervention and contributes to a more consistent surface finish on the workpiece. Where a different chip form is required, selecting an alternative chipbreaker geometry tailored to feed and depth of cut will provide further gains in productivity.

Durable edge life through modern coating technology

The AH6225 grade combines a wear-resistant PVD layer with a substrate formulated for medium cutting forces, extending edge life compared with uncoated grades in similar conditions. The coating reduces flank wear and helps preserve the cutting geometry over longer cycles, lowering tooling consumption and downtime for indexable insert changes. This makes the insert an economical choice when balanced against machining throughput and maintenance intervals.

Practical selection guidance for process optimisation

When specifying an insert, match the 0.8 mm corner radius to radial engagement and surface finish requirements: larger radii give greater robustness, smaller radii improve finish but require more rigid setups. For best results in difficult-to-cut stainless grades, combine the insert’s PVD-coated AH6225 chemistry with stable fixturing and appropriate cutting parameters. If assistance is needed to select the correct chipbreaker or holder combination, Metav Werkzeuge can provide tailored recommendations for the machining task.

FAQ

Which materials is this insert primarily intended for?
The TCMT110308 AH6225 insert is formulated as a universal grade for stainless steels, offering a balance of edge sharpness and toughness for medium turning operations.

How does the hole and countersink affect mounting stability?
The cylindrical hole with a single-side countersink (40°–60°) improves locating and clamping repeatability, so the insert seats securely in ISO-compatible holders and supports stable machining.

What does the AH6225 designation indicate?
AH6225 identifies the PVD-coated carbide grade and its suitability for turning stainless steels, combining wear resistance with a stable cutting edge for variable conditions.

When should a different chipbreaker be chosen?
If the process requires shorter chips, higher feeds or special surface requirements, selecting an alternative chipbreaker matched to feed and depth of cut will improve chip control and finish
