CNMM 160616 T9225 – Turning insert (ISO CNMM160616) by Tungaloy, CVD-coated carbide, 80° geometry

CNMM160616 T9225 is an ISO-standard, rhombic turning insert designed for external and internal turning in medium-to-heavy steel applications, offering consistent chip control and high wear resistance.

• CVD-coated carbide grade T9225
• ISO CNMM160616 rhombic insert, 80° geometry
• 1.6 mm corner radius for stable engagement
• Cylindrical hole, 6.35 mm thickness, single-sided chipbreaker

Consistent metal removal with a tough CVD-coated grade

The combination of a CVD-coated surface and the T9225 grade of carbide delivers a balance of hardness and toughness appropriate for interrupted cuts and variable engagement. CVD coating provides a wear-resistant layer that reduces flank wear and increases tool life, while the substrate retains enough toughness to resist edge chipping under moderate shock. For operations where cycle time and reproducible component quality matter, this construction supports repeatable performance and lower regrind frequency.

Geometry tuned for stability and surface quality

An 80° rhombic geometry paired with a 1.6 mm corner radius reduces the likelihood of chatter and spreads cutting forces across a larger edge, which benefits dimensional stability and surface finish. The 0° relief angle concentrates cutting forces predictably, and the 6.35 mm plate thickness contributes to edge rigidity. The insert’s cylindrical hole and single-sided chipbreaker ensure secure clamping and directed chip formation, facilitating safer chip evacuation and fewer micro-interruptions during long cuts.

ISO compatibility and straightforward tool-system integration

The insert follows ISO standards for shape and dimensions, so compatibility with external holders depends on matching form, relief angle, tolerance class, fixation type, size and thickness. The typical system comprises the ISO insert, a matching external holder or boring bar, a clamp or shim kit and replacement screws. Choose the one-sided chipbreaker and the T9225 grade when machining steels that demand both toughness and abrasion resistance; select alternative chipformers if machining soft alloys or non-ferrous materials to preserve edge integrity.

Productivity, process stability and predictable tool life

Using a grade engineered for medium-to-heavy steel turning promotes process stability and efficient chip control, which together increase overall productivity. The insert’s wear resistance and robust edge reduce unscheduled stoppages for regrinds, while predictable performance supports consistent batch-to-batch quality. For operations prioritising throughput, this indexable geometry and coating combination provide a cost-effective approach to longer cutting intervals and reliable component tolerances.

FAQ

What materials is this insert best suited for? This insert is supplied as a T9225 CVD-coated carbide grade and is optimised for medium-to-heavy steel machining where toughness and abrasion resistance are required.

Can the insert handle interrupted cuts? Yes, the T9225 grade and carbide substrate provide the toughness needed for mildly interrupted and variable engagement conditions during turning.

How does the CNMM160616 geometry affect surface finish? The 80° rhombic shape combined with a 1.6 mm corner radius spreads cutting forces and reduces chatter, which typically improves surface quality and dimensional stability in turning operations.

What determines compatibility with holders and boring bars? Compatibility is determined by insert form, relief angle, tolerance class, fixation type, size and thickness, so match the ISO dimensions and clamping system when selecting a holder.

Is this insert supplied with fastening hardware? The system normally comprises the ISO insert, a matching holder, shim/clamp set and replacement screws; specific hardware is ordered according to the chosen holder system
