CCMT120408 T9225 — ISO turning insert for medium to heavy steel machining, Tungaloy

CCMT120408 T9225 Tungaloy turning insert for ISO-compliant external and internal turning applications, designed for variable engagement and interrupted cuts

• CVD-coated carbide T9225 for steel machining
• Rhombic CCMT 120408 geometry
• 0.8 mm corner radius for robust cuts
• Single-sided chipbreaker for interrupted cuts

Productivity through a wear-resistant grade

The CVD-coated carbide T9225 is engineered as a universal, robust grade for the demands of medium to heavy steel machining. Its surface treatment increases wear resistance and keeps cutting edges stable across varying engagement conditions, which translates into longer tool life and fewer insert changes. This reliability supports higher productivity and reduces process interruptions, making it a sound choice where consistent removal rates and dependable edge behaviour are required.

Geometry and clamping for stable, repeatable results

The rhombic CCMT 120408 geometry with an 80° included angle and a 7° relief enables versatile approach angles while maintaining tool strength. The insert’s design, including the cylindrical hole with a one-sided countersink (40°–60°) and a 4.76 mm thickness, ensures secure clamping in compatible holders. These features reduce vibration and promote repeatable accuracy, so setups stay stable and workpiece tolerance compliance becomes easier to achieve in serial production.

Better chip control and economical edge life

Equipped with a single-sided chipbreaker and a 0.8 mm corner radius, the insert improves chip formation in interrupted and semi-stable cuts. The chipbreaker helps direct swarf away from the cutting zone, lowering recut risk and heat build-up. Combined with the T9225 grade’s toughness, this results in improved edge life and lower tooling cost per part — a tangible economic benefit for workshops focusing on throughput and consistent surface finishes.

System compatibility and selection guidance

The insert follows ISO standard dimensions, so compatibility with a suitable external holder, boring bar or support set is determined by shape, relief angle, tolerance class, fastening style, size and thickness. When selecting a combination, match the chipbreaker and grade to the workpiece material and machine stability. For interrupted cuts or unstable clamping, choose the T9225 grade and a robust holder to exploit the insert’s toughness; for finishing passes, consider smaller engagement and adjust feeds accordingly for improved surface quality. If assistance is needed to match holder type or cutting parameters, technical guidance is available.

FAQ

What materials is this insert suitable for?
The CCMT120408 T9225 insert is specified for medium to heavy steel machining; the T9225 grade provides toughness for variable engagement and lightly interrupted cuts.

Does the insert fit standard CCMT toolholders?
Yes, the insert follows ISO CCMT dimensions; compatibility with a holder depends on form, relief angle, tolerance class, fastening and plate thickness.

How does the chipbreaker affect machining?
The single-sided chipbreaker on this insert improves chip control in interrupted and semi-stable cuts, lowering recut risk and helping to maintain consistent surface finishes.

What benefit does the 0.8 mm corner radius bring?
A 0.8 mm corner radius increases edge robustness for heavier cuts and improves edge life under varying engagement compared with finer radii.

Is the Tungaloy grade suitable for automated production?
The T9225 grade’s balance of wear resistance and toughness makes it reliable for automated and serial production where predictable tool life and consistent results are required.
