CNMM120412 T9235 indexable turning insert for Drehen by Tungaloy — CVD-coated, tough grade for unstable cuts

CNMM120412 T9235 is an ISO-standard indexable insert designed for external and internal turning where interrupted cuts and unstable conditions demand a tough grade and reliable chip control

• ISO indexable insert CNMM120412
• CVD-coated carbide T9235
• One-sided chipbreaker for stable chips
• Rhombic shape with cylindrical hole

Consistent performance in intermittent and unstable turning

The CVD layer combined with carbide substrate forms a wear-resistant cutting edge that favours toughness over sheer hardness; the T9235 grade is engineered for lower cutting speeds and applications where interruptions or vibration occur. This composition reduces the risk of premature chipping and extends edge life, which translates into fewer tool changes and increased machine uptime. The technical design deliberately sacrifices top-range speed for repeatable, robust cutting performance when Stahl components and less-stable setups are present.

Fast, predictable tool changes through ISO compatibility

The insert follows the ISO conventions for form, clearance angle, tolerance and fastening, so compatibility with matched holders and adaptors is straight forward. The rhombic geometry and the cylindrical hole ensure secure clamping and repeatable seating; flange, spacer and screw choices determine final runout. For operations where set-up time matters, this standardisation supports rapid indexation and consistent axial and radial positioning, helping to maintain dimensional stability across batches.

Improved surface finish and chip management for productive cycles

A single-sided chipbreaker directs chips reliably in typical turning passes, aiding evacuation and reducing re-cutting of swarf. The effective combination of the chipformer and a 1.2 mm radius on the insert nose balances edge strength with achievable surface quality, allowing measured feeds that improve part finish without compromising edge life. In unstable cuts the chipflow remains controlled, which lowers the likelihood of built-up edge and contributes to consistently acceptable component surfaces.

Practical geometry and specifications for workshop planning

Key dimensions—4.76 mm thickness, 80° included angle, 0° clearance angle—support machining strategies that demand rigidity and positive seating in the toolholder. The insert’s construction suits both roughing approaches and finishing passes where stability is prioritised over maximum metal removal rates. Combining the grade’s toughness with the insert geometry offers a clear advantage when machining complex batches or mixed-production runs featuring varied clamping conditions.

FAQ

Is this insert suitable for both external and internal turning?
Yes. The CNMM120412 T9235 indexable insert from Tungaloy is specified for external and internal turning (Drehen) and is compatible with ISO holders that match its form and size.

Which materials is the T9235 grade intended for?
The T9235 grade is a tough CVD-coated carbide tailored for machining Stahl at lower cutting speeds and in scenarios with interrupted cuts or unstable conditions.

How does holder compatibility work for this insert?
Compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness; the rhombic shape and cylindrical hole require a matching ISO-compliant holder to ensure correct seating and repeatable clamping.

What chip control can be expected from this geometry?
The single-sided chipbreaker is optimised for stable chip formation in turning operations, supporting reliable evacuation and reducing re-cutting of chips during discontinuous cuts.

What are the key dimensions to plan for in tool setup?
Important dimensions are 4.76 mm thickness, 1.2 mm nose radius, 80° included angle, and 0° clearance angle; use these values to select appropriate clamps, spacers and screws for precise mounting.
