TNMG 160412 T9225 turning insert (ISO) by Tungaloy — triangular 60°, R1.2

A TNMG160412 T9225 ISO indexable insert designed for reliable external and internal turning across a broad range of steel applications.

• ISO triangular insert TNMG 160412 standard
• CVD-coated carbide grade T9225 for steel
• 60° geometry with R1.2 corner radius
• Double-sided insert with cylindrical hole

Robust cutting performance for medium-to-heavy steel

The CVD-coated carbide composition in grade T9225 provides a balanced combination of hardness and toughness tailored to medium-to-heavy steel machining. This makes the insert particularly suitable where changing engagement conditions or lightly interrupted cuts occur, as the grade absorbs impact while maintaining wear resistance. The result is a dependable cutting edge that supports longer productive cycles and reduces unscheduled tool changes, contributing directly to improved process reliability and lower per-part tooling costs.

Precise geometry for repeatable turning accuracy

Built to ISO dimensions, the triangular 60° geometry and R1.2 corner radius ensure predictable chip formation and stable cutting forces during both external and internal turning. The indexable insert features a 0° relief angle and a plate thickness of 4.76 mm, combined with a 16 mm inscribed circle, which simplifies holder selection and set-up. The cylindrical hole and standard form make compatibility with a matching outer holder or boring bar straightforward, provided the holder matches the form, free angle, tolerance class, fastening method, size and thickness — factors that determine secure clamping and consistent repeatability at the tool tip.

Lower tooling cost and easier inventory management

A double-sided design with a dedicated chipbreaker lowers the cost per cutting edge and extends service intervals, improving overall operational uptime. The insert is part of a system that typically comprises a matching outer holder, clamp set and spare screws, allowing pragmatic stocking strategies and fast replacements on shop floors. For operations seeking a practical balance of economy and performance, the combination of a universal grade and standard ISO form supports consolidated inventory and simplified tool management without sacrificing machining quality. The TNMG160412 also integrates well into existing ISO-based tool systems for quick adoption.

FAQ

What materials is this insert suited for?
The Tungaloy TNMG160412 T9225 insert is formulated for medium-to-heavy steel machining and performs well under varying engagement conditions and light interruptions.

What are the key geometric characteristics of the insert?
This indexable insert has a 60° triangular geometry with an R1.2 corner radius, a 0° relief angle and a plate thickness of 4.76 mm, making it suitable for both external and internal turning operations.

Does the insert offer additional cutting life compared with single-sided types?
Yes, the double-sided design provides extra usable cutting edges and an extended service interval, improving cost efficiency and reducing changeover frequency.

How is holder compatibility determined?
Compatibility is determined by the insert form, free angle, tolerance class, fastening method, size and thickness; matching the TNMG160412 with an appropriate outer holder or boring bar ensures secure clamping and repeatable tool positioning.

What coating and grade are used and how do they affect performance?
The insert uses a CVD-coated carbide grade T9225, which combines wear resistance with toughness to handle interrupted cuts and to deliver stable performance in demanding steel machining.
