CNMM 250924 T9235 Wendeplatten - Tungaloy

High process security and predictable tool life are ensured by the combination of a CVD-coated cemented carbide grade and a substantial 9.52 mm plate thickness, making the insert suitable for challenging steel turning tasks; order the CNMM250924 directly via Metav Werkzeuge or request advice from the consultants if required.

CNMM250924 T9235 turning insert by Tungaloy — CVD-coated cemented carbide, 0° clearance

CNMM250924 is an ISO‑standard indexable turning insert designed for external and internal turning in steel applications, offering a robust geometry for interrupted cuts and unstable conditions.

• ISO-compliant geometry for reliable clamping
• CVD-coated carbide grade T9235 for steel
• 0° clearance for robust interrupted cuts
• 2.4 mm corner radius for stable cutting action

Consistent performance for steel turning with a tough grade

The CNMM250924 insert features a CVD-coated cemented carbide substrate and the T9235 grade, a formulation developed for toughness rather than maximum speed. This makes the insert especially suitable where irregular chip load, interrupted cuts or machine instability occur. The combination of coating and grade improves edge resilience and reduces the likelihood of chipping, which translates into fewer unscheduled tool changes and more consistent cycle times on production lines.

Designed geometry for clamping and system compatibility

As an ISO‑standard indexable insert, compatibility with the host toolholder is determined by shape, clearance angle, tolerance class, fastening method, size and thickness. The rhombic plate form and central cylindrical hole allow secure fixing with standard clamp or screw systems. The relatively thick body improves rigidity in the tool system, so paired with a suitable external holder or boring bar the insert contributes to reduced vibration and better surface integrity on turned components.

Practical advantages under unstable conditions and interrupted cuts

The 0° clearance and the one‑sided chipbreaker design are optimised for stable chip formation when conditions are less than ideal. The 2.4 mm corner radius increases edge strength and distributes cutting forces over a larger area, which reduces flank wear and prolongs edge life during heavy engagement. Selecting this insert means prioritising reliability: it is intended for moderate cutting speeds in steel where tool robustness and repeatable results are more important than maximum metal removal rate.

Handling, system components and application guidance

The insert forms part of a system consisting of the ISO indexable plate, a matching external holder or boring bar, a shim/clamping set and spare screws. Plate thickness of 9.52 mm contributes to mechanical stability; the 25 size and 80° included angle suit a broad range of turning operations. For efficient integration, choose a holder with matching tolerance class and fastening arrangement. The one‑sided chipbreaker aids chip evacuation on common turning tasks, simplifying process setup and reducing the need for frequent adjustments.

FAQ

What materials is this insert intended for? The CNMM250924 T9235 insert is formulated primarily for steel machining; the CVD-coated cemented carbide and T9235 grade favour toughness in interrupted or unstable cutting conditions.

Which toolholders are compatible with this insert? Compatibility is determined by the insert geometry and ISO standard: the rhombic shape with cylindrical hole fits ISO‑compliant external holders and boring bars that accept a 25-size CNMM plate and secure it with the appropriate clamp or screw.

How does the 2.4 mm corner radius affect cutting performance? A 2.4 mm corner radius increases edge strength and spreads cutting loads, resulting in improved tool life and more stable surface finishes when machining under heavy engagement or variable chip loads.

Is the insert suitable for interrupted cuts and unstable operations? Yes. The T9235 grade and the insert’s robust 9.52 mm thickness, combined with the one‑sided chipbreaker and 0° clearance, make it well suited for interrupted cuts and cases where machine or workpiece stability is limited.

What system components are required to assemble the insert for use? A complete system typically comprises the ISO indexable plate, a compatible external holder or boring bar, a shim/clamping set and the correct fastening screws; Metav Werkzeuge can advise on the matching holder and spare parts.
