TNMG 220408 T9225 – ISO turning insert by Tungaloy (for turning)

The TNMG220408 T9225 indexable insert is a triangular ISO-format tool insert designed for external and internal turning operations in steel machining.

• CVD-coated carbide T9225
• ISO triangular form 220408
• 0.8 mm corner radius
• Double-sided chipbreaker
• Cylindrical through-hole fastening

Consistent performance in medium to heavy steel turning

The CVD-coated carbide composition of this indexable insert delivers a balance between wear resistance and toughness that suits medium to heavy steel machining. The T9225 grade is formulated to withstand varying cut conditions and slightly interrupted cuts where additional toughness is required. In practice, this means more consistent tool life under changing engagement and machining forces, and predictable dimensional control when facing workpieces that demand repeatable results.

Geometry engineered for repeatable accuracy and efficient changeover

A 60° triangular form compliant with ISO 220408 provides straightforward mounting in standard triangular holders; the cylindrical through-hole fastening ensures secure seating and simple replacement. The insert’s 0.8 mm corner radius and 4.76 mm thickness contribute to stable edge support and resistance to chipping, while the double-sided chipbreaker permits two usable cutting edges per side, improving economics per insert. Compatibility is determined by form, relief angle, tolerance class, fastening style, size and thickness, so selection of the matching holder and clamping set is essential for optimal performance.

Workshop benefits: predictable chips, efficient handling and flexible application

In workshop practice the combination of robust grade T9225, controlled chip formation and the triangular contour reduces unexpected interruptions and simplifies chip evacuation. The insert is suitable for both external and internal turning when paired with the correct holder and chipbreaker variant, allowing straightforward adaptation to serial production or small-batch work. The ISO-format design and common mounting dimensions help to minimise inventory complexity and enable rapid, safe insert changes to reduce downtime.

FAQ

What materials is this insert designed for?
The TNMG220408 T9225 insert is intended primarily for steel machining, offering a robust universal grade suitable for medium to heavy cutting conditions.

How does the T9225 grade influence tool life?
The T9225 CVD-coated grade combines wear resistance with enhanced toughness to cope with variable engagement and slight interruptions, which helps to extend effective tool life in demanding steel operations.

Which pocket and clamping characteristics are required?
Compatibility depends on the ISO triangular form, clearance angle, tolerance class, fastening method and thickness; the TNMG220408 requires a triangular holder compatible with ISO 220408 dimensions and a clamping set designed for a cylindrical through-hole.

How many cutting edges are available per insert?
With a double-sided chipbreaker and a triangular form, the insert offers multiple indexed cutting edges, improving economy by providing more usable edges per insert.

Is this insert suitable for interrupted cuts?
Yes — the insert’s T9225 grade and geometry provide greater toughness, making it appropriate for slightly interrupted cuts encountered in many turning routines.
