TNMG 160420 T9235 indexable turning insert for turning — Tungaloy

TNMG 160420 T9235 is an ISO-standard triangular indexable insert designed for general turning operations, offering a tough CVD-coated carbide grade suited to steel and unstable cutting conditions.

• ISO TNMG 160420 format, triangular insert
• CVD-coated carbide grade T9235 for steel
• Double-sided chipbreaker, suitable for interrupted cuts
• 60° cutting angle with 2 mm corner radius

High reliability under interrupted and unstable cutting

The combination of CVD-coated carbide and the T9235 grade provides increased toughness compared with many general-purpose coatings, which translates into fewer edge failures during interrupted cuts and less frequent insert breakage. The coating is applied via chemical vapour deposition, creating a hard, wear-resistant layer while retaining a resilient substrate; this balance improves chip control and reduces the risk of flank chipping when machining steels at moderate cutting speeds. For workshop teams seeking predictable tool life in variable setups, this insert delivers dependable performance without requiring aggressive cutting parameters.

Precise geometry and secure mounting for repeatable results

The ISO TNMG 160420 format denotes a nominal 16 mm inscribed circle with a triangular plate and a 60° cutting angle, a geometry that supports versatile turning applications. The insert features a 2 mm corner radius and a 4.76 mm thickness, dimensions that give clear indications of allowable depth of cut and edge strength. The plate is supplied with a cylindrical hole, enabling positive clamping in compatible toolholders; compatibility is determined by form, relief/clearance angle (here listed as 0° relief angle), tolerance class, fastening type, size and thickness. These standardized attributes simplify holder selection and help maintain concentricity and repeatability across tool changes.

Efficient use and application guidance for turning operations

Configured with a double-sided chipbreaker, the insert is reversible, effectively doubling the cutting edges available per plate and contributing to a more cost-effective tooling strategy. Typical uses include external and internal turning where intermittent cuts or unstable setups occur; the grade is particularly suited to steel when lower cutting speeds are applied. Selecting the appropriate chipbreaker and grade matching the workpiece material and machine stability will yield the best balance between surface finish and tool life. The geometry and coating together support consistent chip formation and easy disposal of swarf, aiding both process reliability and shop-floor efficiency.

FAQ

What materials is this insert best suited to machine?
The TNMG 160420 T9235 insert is optimised for machining steel; the T9235 CVD-coated carbide grade is formulated for toughness at lower cutting speeds and in interrupted-cut scenarios.

How does the T9235 grade affect tool life compared with general-purpose grades?
Tungaloy’s T9235 grade emphasises resistance to edge chipping and robust performance under instability, which can extend effective tool life in applications with frequent interruptions or variable clamping.

Can the insert be reversed to use the second cutting edge?
Yes, the insert is double-sided with a reversible chipbreaker, allowing the use of multiple cutting corners before replacement is necessary.

Which holder features must be matched to ensure compatibility?
Compatibility requires matching the insert form, relief/clearance angle, tolerance class, fastening method, size and thickness; the TNMG 160420 format and cylindrical hole are standardised for many TNMG holders.

What are the key geometric specifications to consider when planning a turning operation?
Important specifications include the 16 mm inscribed circle, 2 mm corner radius, 4.76 mm thickness and the 60° cutting angle, which influence depth of cut, edge strength and the achievable surface finish.
