TNMG 160408 T9225 TNMG turning insert — CVD-coated carbide, 0.8 mm radius — Tungaloy

TNMG160408 T9225 is an ISO-standard indexable insert for external and internal turning, engineered for medium to heavy steel machining with good toughness for slightly interrupted cuts.

• ISO-standard triangular insert TNMG 160408
• CVD-coated carbide grade T9225
• 0.8 mm corner radius for versatile turning
• Double-sided chipbreaker with cylindrical hole

Consistent cutting performance for demanding steel turning

The combination of a CVD-coated surface and carbide substrate provides a balanced mix of wear resistance and toughness, which supports stable production in harsher cutting conditions. The T9225 grade is formulated as a robust universal option for medium to heavy steel machining, offering predictable edge life where chip formation and occasional interruptions occur. This leads to fewer unexpected tool changes and steadier cycle times on the shop floor, improving throughput without compromising component quality.

Designed for reliable fit and straightforward interchangeability

Manufactured to ISO dimensions, the insert’s triangular form and defined geometry ensure compatibility with standard ISO holders when the form, clearance angle, tolerance class, fastening method, size and thickness match the tooling system. The insert features a 0° clearance angle, a cylindrical hole and a 4.76 mm thickness, which together influence seating accuracy and clamping stability. Clear specification of these parameters permits confident selection of clamping sets and replacement hardware, reducing downtime during indexation or tool changeovers.

Practical advantages and suggested applications

The 0.8 mm corner radius balances strength and finish, allowing controlled engagement in external and internal turning operations while maintaining acceptable surface quality. The double-sided chipbreaker supports consistent chip control across a range of cutting conditions, making the geometry suitable for general-purpose turning as well as slightly interrupted cuts. The system approach — insert plus matching outer holder or boring bar, shim/clamp set and replacement screws — simplifies inventory and promotes efficient tool management in production environments.

FAQ

What materials is this insert suitable for?
The TNMG160408 T9225 insert is intended primarily for medium to heavy steel machining; the T9225 grade offers the toughness needed for variable engagement and slightly interrupted cuts.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO-standard dimensions, but compatibility depends on matching the form, clearance angle, tolerance class, fastening method, size and thickness of the holder.

What is the purpose of the double-sided chipbreaker and cylindrical hole?
The double-sided chipbreaker supports reliable chip control across a range of cutting conditions, while the cylindrical hole enables secure clamping and accurate seating in the chosen holder.

How does the 0.8 mm corner radius affect machining results?
A 0.8 mm corner radius provides a compromise between edge strength and surface finish, making the geometry versatile for a variety of turning tasks, including medium-depth cuts and semi-finishing operations.
