TNMG220412 T9225 – Indexable Turning Insert for Turning by Tungaloy

The TNMG220412 T9225 is a triangular ISO indexable insert designed for external and internal turning, engineered for medium to heavy machining of steel where interrupted cuts or varying engagement demand higher toughness.

• CVD-coated cemented carbide for robust performance
• Triangular 22 mm size, 60° cutting geometry
• Double-sided chipbreaker for consistent chip control
• ISO-compatible with central cylindrical hole for clamping

Consistent productivity under varying engagement conditions

The combination of a CVD coating and a cemented carbide substrate delivers a balance of wear resistance and toughness that suits changing cutting conditions. As a universal grade for medium to heavy steel machining, the T9225 composition sustains edge integrity during light interruptions and fluctuating feed, which keeps tool changeover frequency low and contributes to a smoother production flow. The 60° cutting geometry supports stable turning forces and predictable chip formation.

Simple integration into ISO toolholder systems

Designed to the ISO plate standard, the insert fits common triangular holders when form, clearance angle, tolerance class, clamping and thickness are matched. The central cylindrical hole and standard dimensions (22 mm across flats, 4.76 mm thickness, 1.2 mm corner radius) enable straightforward replacement and predictable seating accuracy, reducing setup time and alignment checks. Clear specification of these parameters allows planners to choose compatible holders and clamping kits with confidence.

Reliable chip control and surface quality

A double-sided chipbreaker provides repeatable chip segmentation across a range of feeds, which aids coolant access and reduces the risk of chip entanglement. That controlled chip behaviour translates into improved surface finishes and fewer secondary operations. When combined with the insert’s toughness, the result is a reliable process window that supports higher productivity without compromising part quality.

Material selection and economical machining

The insert’s grade focuses on stable chip formation and extended life in steel applications, offering good wear resistance while maintaining toughness for interrupted cuts. Using a purpose-designed universal grade reduces the need for multiple specialised grades across mixed batches, simplifying inventory and often lowering total tooling cost per part over time. The ISO-conformant design further supports cost-effective changeovers and consistent repeatability.

FAQ

What materials is this insert suited for?
The TNMG220412 T9225 insert is specified for medium to heavy steel machining and is formulated to handle interrupted cuts and varying engagement conditions.

How does the T9225 grade affect tool life?
The T9225 CVD-coated grade improves wear resistance while retaining toughness, which often extends service life in demanding steel turning applications.

Can the insert be used for internal turning?
Yes, the indexable insert is suitable for both external and internal turning when mounted in an appropriate ISO-compatible holder.

What are the key dimensions to check for holder compatibility?
Verify the ISO designation (TNMG220412), plate size (22 mm), plate thickness (4.76 mm), corner radius (1.2 mm) and the central cylindrical hole to ensure correct clamping and seating.

Is the chipbreaker suitable for long continuous cuts?
The double-sided chipbreaker provides consistent chip control across a range of feeds; it supports both interrupted and continuous cuts, improving process reliability.
