TNMG110408 AH6225 Tungaloy Turning Insert — PVD-coated carbide, 0.8 mm corner radius

TNMG110408 AH6225 Tungaloy insert for ISO-standard external and internal turning, designed for dependable performance on stainless steel in variable workshop conditions

• TNMG 110408 ISO geometry for turning
• PVD-coated carbide grade AH6225
• Double-sided chipbreaker for consistent chips
• 0.8 mm corner radius for improved surface finish

Predictable performance for stainless steel turning

This ISO-format indexable insert delivers a balance of edge sharpness and stability that suits a wide range of turning tasks on stainless steel. The combination of the AH6225 grade and PVD-coated carbide creates a cutting edge that resists built-up edge and maintains form under fluctuating cutting conditions. For machining operations where surface quality and repeatability matter, the insert’s geometry and 0.8 mm corner radius help produce consistent part finishes while reducing the need for rework. The result is improved process stability and better utilisation of machine time.

Compatibility and secure mounting reduce setup risk

Compatibility with toolholders is determined by form, relief angle, tolerance class, fastening method, size and thickness; this ISO insert is configured to match common external holders and boring bars. The 60° triangular shape with a cylindrical hole and a plate thickness of 4.76 mm ensures a reliable clamping interface and repeatable seating. Choosing an insert that adheres to ISO norms simplifies tool inventory management and reduces downtime when replacing cutters. Clear identification by the TNMG110408 designation aids quick selection and prevents mix-ups during tool changes.

Coating and grade designed for productivity

The PVD coating on the cemented carbide substrate acts as a thin, hard barrier against abrasive wear and adhesive tendencies typical of stainless steel machining. Compared with uncoated grades, the coating improves resistance to flank wear and helps maintain cutting-edge integrity under intermittent feeds. The AH6225 grade is optimised as a universal option for stainless steel, offering a compromise between toughness and wear resistance suitable for medium cutting depths and variable conditions. This supports longer, more predictable tool life and lower frequency of indexable insert changes.

Chip control and surface quality in daily production

A double-sided chipbreaker provides consistent chip segmentation on both orientations, assisting controlled evacuation and reducing the risk of tangling or wound-up swarf. For turning operations where chip behaviour affects cycle time and surface integrity, the designed chipformer contributes to safer, cleaner machining and fewer interruptions. The 0.8 mm corner radius also moderates cutting forces and improves edge robustness, which helps when switching between roughing and finishing passes without frequent insert changes.

Practical impact for workshop planning

Adopting this ISO insert supports a rational tooling strategy: standardised dimensions simplify replacement logistics, and the dual-sided design effectively doubles available cutting edges per insert, lowering tooling consumption per component produced. The defined geometry and the PVD-coated carbide composition permit conservative, reproducible cutting parameters that enhance throughput while maintaining quality. For production environments aiming for steady output and predictable tool life, this insert contributes to measurable gains in efficiency and process control.

FAQ

What materials is this insert intended for? The TNMG110408 AH6225 Tungaloy insert is primarily intended for machining stainless steel and is specified as a universal grade for such materials.

How does the PVD coating benefit machining performance? The PVD-coated carbide on the TNMG110408 AH6225 insert increases wear resistance and reduces built-up edge formation, which helps maintain cutting geometry and extend usable edge life.

Can the insert be used on both external and internal turning operations? Yes, the ISO-format insert and its geometry make it suitable for both external and internal turning when paired with an appropriate holder or boring bar.

What are the key dimensions to check for holder compatibility? Verify the insert form, relief angle (0°), tolerance class, fastening method, size (11), and thickness (4.76 mm) to ensure correct seating and secure clamping.
