CNMG 190608 T9235 — CNMG ISO Turning Insert (CVD-coated, TM chipbreaker) by Tungaloy

CNMG190608-TM T9235 is an ISO-standard rhombic turning insert designed for external and internal turning, optimised for steel machining where interrupted cuts or limited rigidity require a tough, reliable grade.

• CVD-coated carbide grade T9235
• TM chipbreaker for interrupted cuts
• ISO CNMG form 190608, rhombic shape
• With cylindrical hole and 0° clearance angle

Consistent performance for unstable turning conditions

The combination of a CVD-coated carbide substrate and the T9235 grade delivers a balance of toughness and wear resistance tailored to turning applications on steel at lower cutting speeds. In practice, this means the insert tolerates shocks and variable engagement better than harder, more brittle grades, reducing the risk of premature edge breakage during interrupted cuts. The rhombic ISO CNMG form with a corner radius of 0.8 mm provides a predictable cutting geometry that supports both finishing and light roughing, while the 0° clearance angle helps maintain positive cutting action in marginal setups.

Improved chip control and longer tool life with TM chipbreaker

The TM chipbreaker is engineered to manage chip formation under unstable cutting conditions. By controlling chip curl and evacuation, the chipbreaker reduces the likelihood of chip entanglement and workpiece rework, which supports a more consistent surface finish. As a result, there is a practical gain in process stability and tool life, particularly when machining interrupted features or less rigid assemblies. The design also helps moderate cutting forces, which contributes to predictable tool wear and simpler parameter optimisation during process setup.

ISO compatibility and system-level reliability

Adherence to ISO dimensions ensures this insert integrates with standard CNMG holders and bar systems; compatibility depends on form, clearance angle, tolerance class, fixation method, size and thickness. The insert’s cylindrical hole and defined thickness of 6.35 mm permit secure clamping with common underlay and clamp sets, while replacement screws are easy to source. For a complete cutting system, pair the insert with a properly rated external holder or boring bar and check that the TM chipbreaker and T9235 grade match the chosen feed, depth of cut and machine rigidity. This system-focused approach reduces setup iterations and supports repeatable, productive turning cycles.

FAQ

What materials is this insert best suited for?
The CNMG190608-TM T9235 insert is optimised for steel machining; the T9235 grade and CVD coating provide toughness and wear resistance appropriate for lower cutting speeds and interrupted cuts.

Can this insert be used for both external and internal turning?
Yes. The rhombic CNMG form and the 0° clearance angle make the insert suitable for both external and internal turning operations when paired with the correct holder and clamping system.

How does the TM chipbreaker affect machining?
The TM chipbreaker improves chip control during interrupted and unstable cuts, leading to more consistent surface finish and reduced risk of chip-related incidents, which helps extend effective tool life.

What dimensions and features ensure holder compatibility?
Holder compatibility depends on form, clearance angle, tolerance class, fixation, size (19 mm) and thickness (6.35 mm); the insert’s cylindrical hole also aligns with standard clamping designs for secure fixing.

Is this an original Tungaloy product and how is it identified?
Yes, the insert is an original Tungaloy indexable insert identified as CNMG190608-TM T9235 with article number 6785921 and manufacturer SKU TUN6785921.
