CNMM 190616 T9225 — ISO rhombic indexable insert for turning — Tungaloy

CNMM 190616 T9225 is an ISO rhombic indexable insert designed for external and internal turning, offering robust performance in medium to heavy steel machining

• ISO rhombic insert CNMM 190616
• CVD-coated carbide grade T9225
• 1.6 mm corner radius for robust cuts
• Single-sided chipbreaker, with cylindrical hole

Consistent cutting performance for medium to heavy steel

The combination of a CVD-coated carbide substrate and the T9225 grade provides an engineered balance of hardness and toughness, optimised for the variable demands of medium to heavy steel turning. The 1.6 mm corner radius increases edge strength under heavier depths of cut and intermittent engagement, reducing edge failure and supporting longer tool life. This grade is intended where slightly interrupted cuts or changing engagement demand additional toughness rather than only maximum wear resistance. The result is more predictable performance across batch runs and hardened production cycles.

Geometry and clamping that simplify setup and accuracy

The rhombic geometry with an 80° included angle and a 0° clearance promotes versatile insert positioning for both external and internal turning applications. Compatibility with a holder is determined by form, clearance angle, tolerance class, clamping method, size and thickness; the insert forms part of a system comprising an ISO insert, a matching external holder or boring bar, a shim/clamping set and replacement screws. The 6.35 mm thickness and the central cylindrical hole ensure secure clamping and repeatable seating, which stabilises cutter engagement and helps maintain dimensional accuracy in serial production.

Shop-floor advantages that raise productivity and finish quality

A single-sided chipbreaker tailored to the grade and geometry assists chip formation and evacuation under heavier feeds, improving process stability and reducing rework. Secure clamping via the cylindrical hole minimises insert movement during interrupted cuts, translating to fewer insert changes and higher uptime. Together, these attributes support a reduction in cycle times and help deliver a consistent surface finish, making the insert a practical choice for production departments seeking dependable throughput with predictable maintenance intervals.

Material scope and recommended applications

The CNMM 190616 T9225 insert is targeted at turning steel in medium to heavy machining tasks where robustness is essential. The CVD-coated surface provides enhanced wear resistance while the substrate toughness resists chipping under less favourable cutting conditions. For best results, select a matching chipbreaker and a holder that provides stable support; the insert is suitable for both external and internal turning operations and adapts well to jobs with variable engagement and interrupted cuts.

FAQ

Which materials are best processed with this insert?
The CNMM 190616 T9225 insert is optimised for medium to heavy steel machining; the CVD-coated carbide and the T9225 grade combine wear resistance and toughness for these materials.

What is the corner radius and why does it matter?
The insert has a 1.6 mm corner radius, which increases edge strength for heavier cuts and intermittent engagement, helping to avoid chipping and extend tool life.

How can I ensure compatibility with my holder?
Compatibility depends on the insert form, clearance angle, tolerance class, clamping method, size and thickness; the CNMM190616 designation and the ISO series should be matched to a compliant holder and the appropriate shim/clamping set.

Is the chipbreaker suitable for interrupted cuts?
Yes; the single-sided chipbreaker paired with the T9225 grade supports controlled chip formation under heavier feeds and interrupted cutting conditions.

Can this insert be used for internal boring as well as external turning?
Yes, the ISO rhombic geometry and the central cylindrical hole allow use in both external turning and internal boring when mounted in a compatible boring bar or holder.
