TNMM 220408 T9225 – ISO turning insert (CVD-coated carbide, 60°) by Tungaloy

TNMM 220408 T9225 is an ISO-standard triangular turning insert developed for medium to heavy steel machining, combining a tough CVD-coated carbide grade with a chipbreaker suited to variable and lightly interrupted cuts.

• CVD-coated carbide grade T9225
• Triangular insert with 60° cutting edge
• 0° clearance angle for enhanced rigidity
• Optimised for medium to heavy steel turning

Durable grade for changing and demanding cuts

The T9225 grade offers a CVD-coated, carbide substrate designed as a robust universal solution for turning tasks where cutting conditions vary or slight interruptions occur. The combination of coating and substrate delivers increased toughness compared with some purely wear-focused grades, which means fewer insert failures under fluctuating loads and a more reliable production rhythm. With the chipbreaker 57 matched to the grade, chip formation is stabilised for a broad range of steels, reducing rework and supporting consistent component quality.

Rigid geometry for precision and repeatability

A triangular outline with a 60° cutting geometry provides three usable cutting corners and good access for a variety of external and internal turning setups. The specified corner radius of 0.8 mm and a plate thickness of 4.76 mm contribute to cutting edge stability, while the 0° clearance angle supports high rigidity at the cutting zone. The insert’s cylindrical hole ensures positive clamping and repeatable seating in the cartridge or holder, which improves surface finish consistency and extends the usable life of both insert and tool body.

System compatibility that reduces downtime

Supplied as part of an ISO insert system, the plate is matched to external holders or boring bars together with the appropriate shim or clamp set and replacement screws. Compatibility is driven by the insert form, clearance angle, tolerance class, fastening type, size and thickness, so choosing the correct holder ensures secure clamping and minimal changeover times. The standardised format simplifies stock control and enables quick insert changes to maintain machine uptime and throughput.

Application guidance for reliable productivity

The insert is primarily intended for medium to heavy steel turning and is suitable for interrupted cuts thanks to its tougher substrate and chip control geometry. Selection of feed and speed should reflect component material, machine rigidity and coolant strategy; the grade’s balanced wear resistance and fracture strength promotes longer tool life and steady productivity in batch production and single-piece flows alike. For specialised alloys or non-steel materials, consult technical data to match chipbreaker and grade to the application.
