CNMM250924 T9225 CNMM Turning Insert by Tungaloy — CVD-coated carbide, 2.4 mm radius

CNMM250924 is a rhombic ISO indexable insert designed for medium to heavy steel turning, offering robust performance in interrupted and variable-cut conditions.

• ISO rhombic insert CNMM250924 by Tungaloy
• CVD-coated carbide grade T9225 for steel
• 2.4 mm corner radius for reinforced edge
• Single-sided chipbreaker with cylindrical hole

Stable performance under changing cutting conditions

The CVD-coated carbide substrate combined with the T9225 grade is engineered for consistent toughness and wear resistance during medium to heavy steel turning. The coating supports thermal stability at elevated cutting speeds, while the grade emphasises reliable chip control and edge integrity when cuts are slightly interrupted or engagement varies. As a result, the indexable insert offers repeatable tool life and predictable performance, which reduces tool-change frequency and supports steady production throughput.

Secure clamping and system compatibility for reduced downtime

Compatibility with toolholders depends on form, relief angle, tolerance class, fastening, size and thickness; the insert's rhombic geometry and cylindrical hole accommodate standard clamping systems. The 9.52 mm plate thickness and standard ISO dimensions facilitate straightforward mounting in suitable CNMM holders or on boring bars, with the requirement to match the holder pocket and fastening screw. This simplified integration helps to minimise setup time and lowers the risk of incorrect fitting that can cause premature wear or component rejection.

Edge strength and chip control for productive turning

A 2.4 mm corner radius provides a reinforced cutting edge that balances strength and surface finish for steel machining. The single-sided chipbreaker is optimised for reliable chip formation in a range of cutting depths and feed rates, reducing the likelihood of long, entangling chips and supporting safer, uninterrupted operation. When combined with appropriate cutting data for the workpiece and machine rigidity, the insert contributes to consistent surface quality and process security.

Practical assembly and application notes for workshop use

The insert is part of an ISO-compliant system comprising the indexable insert, a matching external holder or boring bar, a shim/clamp set and replacement screws. The 80° cutting geometry and 0° relief angle are typical for CNMM-style rhombic inserts and should be matched to the intended turning strategy. For best results in medium to heavy steel work, select cutting parameters in line with the toolholder rigidity and the T9225 grade's balance of toughness and wear resistance to extend tool life and maintain machining stability.

FAQ

What materials is this insert suited for? The CNMM250924 T9225 indexable insert is designed primarily for steel; the T9225 grade provides toughness and wear resistance for medium to heavy steel turning.

Does the insert fit standard CNMM holders? Yes. The CNMM250924 geometry and the cylindrical hole conform to ISO CNMM dimensions and are compatible with appropriately matched holders and boring bars when form, relief angle and thickness are observed.

What benefits does the CVD coating provide? The CVD-coated carbide offers enhanced thermal stability and wear resistance, helping the insert maintain edge life at higher temperatures common in medium to heavy turning operations.

How does the 2.4 mm corner radius affect machining? A 2.4 mm corner radius increases edge strength and reduces chipping risk under variable engagement, supporting stable cutting in heavier or interrupted cuts while contributing to surface integrity.

What are the key system components required for installation? Proper installation requires a matching external holder or boring bar, a shim/clamp set and the correct replacement screws specified for CNMM-style inserts; ensuring correct assembly supports reliable machining.
