CNMG120408 T9205 — Tungaloy indexable turning insert for Turning

CNMG120408 T9205 is an ISO-format indexable insert designed for productive external and internal turning in stable machining conditions.

• CVD-coated carbide for high wear resistance
• 80° rhombic geometry for robust engagement
• Double-sided insert with cylindrical hole
• Corner radius 0.8 mm for reliable edge strength

Consistent productivity for Stahl turning

The CVD-coated carbide construction combined with the T9205 grade delivers enhanced wear resistance under elevated cutting speeds, making the insert particularly suited to productive turning of Stahl. The coating optimises thermal and abrasive resistance, which reduces flank wear and extends in-cycle tool life; this translates into fewer indexings and longer uninterrupted production runs. For machining operations that demand steady metal removal rates, the insert’s balance of edge stability and coating performance supports reproducible part quality and predictable tool-change intervals.

Clear compatibility and secure clamping for fast tool setup

As an ISO-standard turning plate, compatibility with toolholders is governed by form, clearance angle, tolerance class, fastening method, size and thickness. The ISO designation ensures interchangeability with compatible CNMG holders when those parameters match. The plate’s 0° clearance and 4.76 mm thickness provide dimensional stability during clamping, while the 12 mm inscribed size matches common external holders. This clarity in mounting data assists process planners in selecting the correct holder–insert pairing and reduces setup time on the shop floor.

Cutting geometry and grade engineered for stable chips and surface finish

The rhombic shape with an 80° cutting angle and double-sided chipbreaker offers a dependable compromise between chip control and cutting edge life. The corner radius 0.8 mm is chosen to give sufficient edge strength for medium-to-heavy cuts while still allowing good surface quality in finishing passes. The cylindrical hole provides a stable datum for the clamping screw, contributing to repeatable positioning and consistent results across indexings. Overall, the geometry and the T9205 composition are geared towards productive, predictable turning operations where process security and tool-life economy matter.

FAQ

Is this insert suitable for both external and internal turning?
Yes. The CNMG120408 T9205 indexable insert is intended for external and internal turning applications under stable machining conditions where the T9205 grade excels at higher cutting speeds.

Which workpiece materials are recommended for this grade?
The T9205 grade is specified for productive machining of Stahl and is optimised for wear resistance during steel turning.

How is the insert secured in the holder?
The plate is located by the cylindrical hole and clamped with the appropriate screw and clamp set; compatibility requires matching the holder by form, clearance angle, tolerance class, fastening method, size and thickness.

Can the insert be indexed and reused?
Yes. The double-sided, indexable design allows rotation to a fresh cutting edge; the geometry and CVD coating support multiple indexings with consistent performance.

What cutting conditions suit the 0.8 mm corner radius?
A corner radius of 0.8 mm offers a balance between edge strength and surface finish, making it suitable for medium-depth turning and semi-finishing passes where robustness and acceptable finish are required.
