TNMG 220412 T9205 ISO turning insert for turning – Tungaloy

TNMG220412 T9205 is a triangular ISO turning insert designed for productive external and internal turning of steel under stable cutting conditions

• CVD-coated carbide T9205 for steel machining
• 1.2 mm corner radius for robust edge life
• Double-sided, triangular insert with cylindrical hole
• ISO 220412 profile, 60° geometry

High productivity and controlled wear for steel turning

The insert delivers consistent removal rates through its CVD-coated carbide composition, grade T9205, which is engineered for productive turning of steel at elevated cutting speeds. The coating improves wear resistance and reduces flank wear, extending the interval between indexings. With a 60° cutting geometry and a 1.2 mm corner radius, the design provides a compromise between edge strength and accessibility for semi-finish and finish passes. The result is a measurable increase in process stability and predictable tool life under steady clamping and machine conditions.

Secure clamping and versatile ISO compatibility

Constructed to the ISO-Drehwendeschneidplatten specification, the insert features a cylindrical hole and standard triangular form that simplify mounting in compatible external holders and boring bars. Compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness; the 4.76 mm thickness and 22 mm inscribed circle make the insert suitable for a broad range of ISO tooling systems. The double-sided layout allows both edges to be used, improving economy per indexable unit while maintaining repeatable positioning for accurate cutting.

Practical benefits from geometry and chip control

A doppelseitig chipbreaker arrangement provides effective chip segmentation for stable swarf evacuation during turning operations. The 0° clearance angle and the triangular plate shape produce predictable cutting forces and surface finish when paired with the appropriate holder and machining parameters. For workshops seeking cost-efficient throughput, this geometry reduces setup iterations and supports steady-cycle production where consistent dimensional results and surface quality are required.
