CPMT 09T302 T9215 turning insert by Tungaloy — CVD-coated carbide, rhombic ISO insert for turning

CPMT09T302 T9215 is an ISO-standard rhombic turning insert designed for general external and internal turning of medium steels, combining a wear-resistant coating with geometry optimised for continuous to light interrupted cuts.

• CVD-coated carbide T9215 for steels
• ISO rhombic form with cylindrical hole
• 11° clearance angle for stable cutting
• 0.2 mm nose radius for fine finishes

Productive cutting with a wear-resistant grade

The T9215 cutting grade is a CVD-coated carbide specifically developed for medium steel machining where a balance of high wear resistance and fracture toughness is required. This combination reduces flank and crater wear under continuous or slightly interrupted cuts, allowing longer tool life and more predictable change intervals. The coating process forms a hard, adherent layer that improves abrasive wear resistance; in practical terms, this translates into fewer insert changes and a steadier production rhythm on the shop floor.

Precise geometry for consistent assembly and accuracy

Supplied as an ISO-standard rhombic insert with a cylindrical hole and a single-sided countersink (40°–60°), the geometry ensures repeatable seating in compatible holders. The 11° clearance reduces rubbing and surface heat, contributing to improved dimensional control and surface finish. Compatibility with a holder depends on the insert form, clearance angle, tolerance class, fastening method, nominal size and thickness; matching these parameters prevents clamping play and maintains concentricity during both external and internal turning operations.

Fine finishing and controlled chip formation

With a 0.2 mm nose radius and a plate thickness of 3.97 mm, the insert is suitable for fine finishing passes and stable roughing when machine and setup rigidity permit. The one-sided chipbreaker geometry promotes controlled chip flow for typical steel grades, helping to avoid long, tangled chips and improving process safety. For best outcomes, pair the insert with an appropriately rigid holder and select cutting data that reflects workpiece stability and the chosen grade’s capabilities.

Practical application guidance and selection advice

The insert is intended for turning operations and performs well in both external and internal applications on medium-strength steels under continuous to light interrupted cuts. Select the chipbreaker and grade according to the workpiece material and the machining mode: choose T9215 for parts where wear resistance and fracture safety are priorities. For uncertain fits or to optimise cutting parameters for specific components, seek application support to ensure holder compatibility and to avoid unnecessary tool wear or poor surface finish.

FAQ

What materials is this insert best suited for?
The CPMT09T302 T9215 insert is optimised for medium steels; the T9215 CVD-coated carbide balances wear resistance and fracture toughness for productive steel turning.

How is the insert secured in the holder?
This rhombic insert uses a cylindrical hole with a single-sided countersink (40°–60°) for centre clamping; compatibility depends on holder form, size, clearance and fastening method.

Can this insert be used for internal turning?
Yes, the ISO geometry and rhombic form make the insert suitable for both external and internal turning when paired with an appropriate holder.

What surface finish can be expected with a 0.2 mm radius?
A 0.2 mm nose radius typically yields fine finishes on steels when combined with correct feeds and a rigid setup; it is suitable for finishing passes and light semi-finishing.

Is the insert suitable for interrupted cuts?
The grade is designed for continuous to light interrupted cuts; for heavily interrupted machining, a different grade or a more robust geometry may be advisable.
