CNMG120408 T9235 indexable turning insert for turning — Tungaloy

CNMG120408 T9235 is an ISO-form indexable insert for external and internal turning, engineered for steel machining where interrupted cuts or variable rigidity occur

• CVD-coated carbide grade T9235
• Suited for unstable turning conditions
• ISO-compliant CNMG120408 geometry
• Double-sided insert with cylindrical hole

Improve productivity in interrupted and unstable turning

The combination of a CVD-coated surface and a carbide substrate delivers a balance of toughness and wear resistance for steel applications. This specification reduces the rate of edge breakdown under variable loads, enabling longer tool life and fewer insert changes. The CVD layer improves high-temperature resistance and protects the substrate during tougher engagements, which translates into more consistent cycle times and reduced process variation on batch production runs. The double-sided design and robust chip control contribute directly to uptime and predictable reconditioning intervals.

Faster setup and predictable holder compatibility

As an ISO-compliant CNMG geometry, the insert simplifies integration with industry-standard holders; compatibility is governed by shape, relief angle, tolerance class, clamping method, size and thickness. The insert measures 12 mm across the inscribed circle and has a thickness of 4.76 mm, a corner radius of 0.8 mm and a relief angle of 0° with an 80° lead angle—dimensions that make locating and clamping straightforward in stable toolholders. The cylindrical locating hole ensures positive seating and repeatable clamping, reducing set-up time and minimising indexing errors during tool changeovers.

Purpose-built for steel: benefits and selection advice

The T9235 grade is a tough, CVD-coated carbide developed for steel at moderate cutting speeds and in situations with interrupted cuts or limited rigidity. For operators, this means the insert tolerates shock loads better than harder, more wear-resistant grades, while still offering acceptable flank and crater wear characteristics. Match the double-sided chipbreaker to the workpiece and rigidity: a more aggressive chipformer for stable setups, a milder form for lighter machines or longer overhangs. Where surface finish and dimensional stability are critical, combining this grade with appropriate feeds and coolant strategy will deliver consistent results and lower scrap rates.

FAQ

How does the T9235 grade behave on steel?
The CNMG120408 T9235 indexable insert uses a tough, CVD-coated carbide that withstands interrupted cuts and variable loads, providing stable chip formation and extended edge life in steel turning.

Is the geometry compatible with standard CNMG holders?
Yes. The CNMG120408 geometry is ISO standard; however, holder compatibility depends on form, relief angle, tolerance class, clamping method, size and thickness, so check the holder specification before fitting.

What do the 0° relief and 80° lead angles mean in practice?
A 0° relief gives a neutral clearance suitable for many turning tasks, while the 80° lead angle offers a compromise between radial engagement and axial stability, improving strength at the cutting edge during heavier cuts.

Can the insert be indexed to a fresh cutting edge?
The double-sided rhombic design allows rotation and indexing to present a new edge, extending usable life compared with single-edge inserts and supporting economical tool usage.

Which chipbreaker should be chosen for variable rigidity?
Select the chipbreaker that matches the material and machine stability: the double-sided chipformer on this insert provides flexibility, but a milder form is recommended for machines with longer tool overhang or less rigidity.
