CNMM 190624 T9235 ISO turning insert — 80° rhombic, CVD-coated (Tungaloy)

The CNMM 190624 T9235 is an ISO-indexed turning insert designed for external and internal turning of steel, offering a tough, CVD-coated carbide grade for lower cutting speeds and interrupted cuts.

• CVD-coated carbide grade T9235
• Rhombic 80° geometry
• 2.4 mm corner radius
• Cylindrical hole for secure clamping

Reliable performance where stability is limited

The combination of a CVD-coated surface layer and a tough cemented carbide substrate makes this insert particularly suited to turning tasks with interrupted cuts or variable rigidity. The T9235 grade is engineered for lower cutting speeds, prioritising resistance to mechanical shock and flank wear rather than top-end speed. The single-sided chipbreaker geometry supports controlled chip formation when cutting steels with varying machinability, which reduces the risk of built-up edge and minimises downtime for rework. For engineers seeking predictable cycle times and longer edge life under unstable conditions, the insert’s balanced construction reduces the need for overly conservative feed rates while maintaining acceptable surface integrity.

Secure clamping and straightforward tool compatibility

Being ISO-indexed, the insert fits standard holders when form, clearance angle, tolerance class, fixing method, size and thickness are matched. The rhombic 80° geometry and cylindrical hole enable positive seating and repeatable clamping torque, while the 6.35 mm thickness and 19 mm inscribed size provide a stable platform for axial and radial loads. The 0° clearance specification is part of the insert geometry that affects approach angles and must be considered with the selected holder to achieve the intended cutting edge engagement. Clear identification of these parameters simplifies tool setup and reduces trial-and-error at the machine, enabling faster changeovers and consistent machining results across multiple tool assemblies.

Grade selection and application guidance for steel turning

When machining steel under interrupted cuts or in less rigid setups, the T9235 grade favours toughness over maximum wear resistance; it is therefore recommended for stepped shoulders, parting lines and applications with varying chip thickness. The 2.4 mm corner radius offers a compromise between strength and surface finish: it supports higher cutting forces than very small radii while still allowing satisfactory component tolerances. For finishing passes or where surface roughness is critical, select feeds that match the corner radius to avoid chatter or unsupported edges. If the process requires alternative chip control or higher cutting speeds, choose a different chipbreaker or a harder, more wear-resistant grade; our catalogue and consultants can advise on the optimal combination of chipbreaker and grade for the specific steel alloy and machining strategy.

FAQ

What materials is this insert designed for? The Tungaloy CNMM 190624 T9235 insert is formulated primarily for machining steels; the T9235 grade emphasises toughness for interrupted and unstable cutting conditions.

How does the T9235 grade differ from other grades? T9235 is a tough, CVD-coated cemented carbide grade intended for lower cutting speeds and conditions with higher mechanical impact, trading some high-speed wear resistance for improved edge strength.

Can the CNMM 190624 be used for internal turning? Yes, the ISO-indexed CNMM 190624 geometry and its secure clamping via the cylindrical hole make it suitable for both external and internal turning operations.

Which chipbreaker should be selected for variable material conditions? The single-sided chipbreaker supplied with this insert is a general-purpose option; for specific steels or highly interrupted cuts, adjust the chipbreaker type to match material, feed and stability requirements.

What dimensions are critical when choosing a compatible holder? Key dimensions include the insert thickness (6.35 mm), inscribed circle (19 mm), corner radius (2.4 mm) and the 80° rhombic geometry—match these to the holder’s seat, clearance and clamping method.
