TNMG 160412 T9225 Turning insert (Turning) – Tungaloy

The TNMG160412 T9225 is an ISO-standard triangular turning insert engineered for medium to heavy steel machining, offering a CVD-coated carbide grade and reliable chip control for variable cutting conditions.

• ISO triangular insert, 60° geometry
• CVD-coated carbide grade T9225
• Double-sided chipbreaker for stable chips
• Cylindrical hole for secure mounting

Consistent productivity under varied cutting conditions

The T9225 grade is a CVD-coated carbide developed as a robust universal solution for medium to heavy steel machining where variable engagement or mildly interrupted cuts demand extra toughness. The coating improves wear resistance and maintains edge integrity under fluctuating loads, which reduces insert change frequency and supports a stable production rhythm. As a consequence, machining cycles become more predictable and tool costs are balanced by longer effective life and fewer unscheduled stops.

Secure clamping and straightforward tool setup

A triangular plate with a 60° geometry and a cylindrical hole provides a reliable seating and repeatable positioning in standard ISO holders. Compatibility is determined by plate form, clearance angle, tolerance class, fastening style, size and thickness; the ISO-standard designation simplifies matching with common external holders or boring bars. The insert’s 1.2 mm corner radius and insert thickness 4.76 mm contribute to mechanical strength at the cutting edge, enabling safe feeds and stability when paired with a suitable clamping system.

Better chip control for reduced downtime

The double-sided chipbreaker design promotes consistent chip formation and evacuation, which helps to prevent entanglement and improves surface finish on the workpiece. By directing chips reliably away from the cutting zone, the insert reduces heat concentration and tool wear, supporting longer intervals between inspections. This feature is particularly beneficial when machining steels that produce long, stringy chips or when interrupted cuts occur, as it enhances process reliability and operator safety.

Practical application guidance for turning operations

Typical uses include external and internal turning where a universal, tough grade is required. Select a holder and chipbreaker combination appropriate to the workpiece material, depth of cut and machine stability; the insert integrates into systems comprising the ISO triangular plate, matched holder or bar, support pad/clamping set and replacement screws. For best results, pair the plate with rigid fixturing, moderate feeds that suit the 1.2 mm corner radius, and coolant practices consistent with the material and cutting data supplied.

FAQ

What materials is this insert intended for?
The TNMG160412 T9225 insert is intended primarily for medium to heavy steel machining; the T9225 grade provides extra toughness for variable engagement and light interruptions.

How does the double-sided chipbreaker affect machining?
A double-sided chipbreaker on this triangular insert improves chip control and evacuation, which supports consistent surface finish and reduces the risk of chip-related interruptions.

What dimensions and geometry should be noted when selecting a holder?
Key dimensions are the 60° included angle, 16 mm plate size and 4.76 mm thickness; holders must match form, clearance angle, tolerance and fastening style to ensure correct compatibility.
