TNMG 220408 T9215 turning insert by Tungaloy

TNMG 220408 T9215 is an ISO-standard triangular turning insert designed for medium steel machining and compatible with ISO holders that match form, clearance and fastening specifications.

• CVD-coated carbide grade T9215 for wear resistance
• Suited to medium steel turning operations
• Triangle form with 60° included angle
• Double-sided chipbreaker for stable chips

Higher throughput with a wear-resistant coating

The combination of a CVD-coated surface and a wear-resistant carbide substrate provides a clear productivity advantage in medium steel applications. The coating reduces flank and crater wear during continuous and slightly interrupted cuts, which extends tool life and lowers tooling costs per component. Choosing the T9215 grade balances abrasion resistance and fracture toughness, allowing longer cutting times and fewer tool changes without compromising process stability.

Accurate seating and secure clamping for repeatable results

The ISO triangle form with a 60° included angle and a cylindrical locating hole ensures consistent seating in compatible holders, reducing vibration and positional error. The insert’s dimensions — 22 mm size and 4.76 mm thickness — match common ISO holders, while the 0° clearance angle contributes to predictable cutting geometry. These attributes support repeatable part tolerances and make toolpath planning and fixture selection more straightforward.

Controlled chip formation and consistent surface finish

A 0.8 mm corner radius combined with a double-sided chipbreaker produces stable chip formation and improved surface integrity on medium steel. The moderate corner radius helps achieve smoother finishes while maintaining acceptable edge strength for productive feeds. Selecting a chipbreaker and grade appropriate to the workpiece material reduces downtime for chip evacuation and cleaning, which supports steady cycle times and consistent part quality.

Practical compatibility and system considerations

As an ISO-standard insert, integration into an existing tool system requires matching form, clearance, tolerance class, fastening method and size. The insert functions as part of a system: insert + external holder or boring bar + clamping shim/screws. When these elements are matched correctly, the result is a robust setup that minimises tool deflection and improves dimensional reliability during turning operations.

FAQ

What applications is this insert best suited for?
This insert is intended for medium steel turning; the T9215 CVD-coated carbide is optimised for a balance of wear resistance and toughness, making it suitable for continuous to slightly interrupted cuts.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius improves surface finish while retaining adequate edge strength for general finishing and semi-finishing operations on medium steel.

Is the TNMG220408 compatible with standard ISO TNMG holders?
Yes, the TNMG220408 follows ISO geometry; compatibility depends on matching form, clearance, tolerance class, fastening and thickness with the chosen holder.

What benefits does the CVD coating provide on this grade?
The CVD coating enhances abrasion resistance and reduces flank wear, which increases tool life and supports higher process stability during extended runs.
