CCMT120404 T9215 ISO turning insert — rhombic CCMT for medium steel by Tungaloy

The CCMT120404 T9215 is an ISO-standard rhombic turning insert designed for medium steel machining, combining a CVD-coated carbide grade with a single-sided chipbreaker for continuous to lightly interrupted cuts.

• CVD-coated carbide grade T9215
• ISO CCMT120404 rhombic insert
• 0.4 mm nose radius for fine finish
• 7° clearance angle, with hole and countersink

Higher productivity through a wear-resistant coating

The CVD-coated carbide grade T9215 is formulated as a first choice for medium steel machining, offering a combination of wear resistance and fracture toughness that supports elevated cutting speeds. This material/coating pairing enables longer tool life under continuous operation and helps to keep component tolerances within narrow limits, which reduces rework and increases throughput. The result is a tangible improvement in cycle-time efficiency for batch production where consistent performance matters.

Consistent surface quality thanks to optimised geometry

A rhombic geometry with an effective 0.4 mm nose radius and an included angle of 80° provides a balance between edge strength and surface finish. The modest nose radius helps achieve a fine machined surface without compromising flank robustness, while the 7° clearance reduces rubbing and heat build-up. Together these features support dimensional accuracy and repeatable finishes in external and internal turning, especially when paired with the correct feed and speed settings for the workpiece material.

System compatibility and practical handling for workshop use

ISO standardisation ensures reliable fitment: compatibility with a holder depends on form, clearance angle, tolerance class, fastening, size and thickness, so the insert integrates into common turning systems alongside a matching outer holder or boring bar, pad/clamping set and replacement screws. The insert is supplied with hole and a cylindrical hole plus single-sided countersink (40°–60°) to match typical clamping arrangements. The single-sided chipbreaker simplifies chip control for medium steels, reducing manual intervention and contributing to a more predictable production flow.

FAQ

Is this insert suitable for medium steel machining?
Yes. The CCMT120404 in grade T9215 is specified for medium steel and combines wear resistance with fracture toughness to support productive continuous to slightly interrupted cutting.

How does the chip control perform with this grade?
The single-sided chipbreaker and the CVD-coated carbide construction provide effective chip control for medium steels, reducing the need for operator intervention and improving process stability.

What holder features are required for correct compatibility?
Compatibility depends on insert form, clearance angle, tolerance class, fastening, size and thickness; the ISO designation CCMT120404 ensures fitment with holders designed for that standard geometry.

Can the insert handle light interruptions in the cut?
Yes. The grade and geometry of this insert are engineered to tolerate continuous to lightly interrupted cuts while maintaining edge integrity.

Is the insert provided with clamping provisions?
The insert is supplied with hole and a cylindrical hole plus single-sided countersink (40°–60°) to suit common clamping systems.
