CPMT 090304 T5115 turning insert — CVD-coated cemented carbide, rhombic 09 (80°) by Tungaloy

The CPMT090304 T5115 Tungaloy insert is an ISO rhombic turning insert engineered for external and internal turning of cast iron, featuring a single-sided chipbreaker and a cylindrical hole with a single-side countersink for secure clamping

• ISO rhombic 09, 80° geometry
• CVD-coated cemented carbide T5115
• 0.4 mm corner radius for consistent edge
• Cylindrical hole with single-side countersink

Consistent performance for cast-iron turning

The indexable insert delivers a dependable balance between wear resistance and edge stability thanks to the T5115 CVD-coated grade. Designed specifically for machining cast iron, the combination of coating technology and substrate hardness reduces flank wear and maintains cutting-edge integrity across interrupted cuts. The CVD layer improves resistance to built-up edge and thermal loading, which contributes to longer intervals between tool changes and more predictable production cycles.

Secure clamping and ISO compatibility to simplify setup

Compatibility with ISO-standard holders is determined by plate form, relief angle, tolerance class, fixation method, size and thickness; this insert aligns with those parameters to enable straightforward integration into existing toolholders. The cylindrical hole with single-side countersink (40°–60°) ensures secure clamping, while the 11° clearance angle preserves the intended cutting geometry. These characteristics reduce setup time and support repeatable, accurate clamping, which is essential for maintaining part tolerances in serial production.

Edge geometry engineered for reliable finishes and tool life

The 0.4 mm corner radius balances strength and surface finish, offering sufficient edge robustness for roughing passes while allowing acceptable surface quality in finishing operations. The single-sided chipbreaker controls chip formation for the typical chip form of cast iron, preventing entanglement and promoting consistent evacuation. A plate thickness of 3.18 mm contributes to overall stability during cutting, lowering vibration risk and supporting a uniform machined surface.

Productivity and application guidance for efficient machining

Selecting the correct chipbreaker and grade for the workpiece and machining stability is decisive for productivity. The T5115 grade provides a universal solution for cast-iron applications, enabling productive machining across a range of speeds and feeds. For optimal results, pair the insert with a suitable ISO holder matched for form, size and tolerance class; this combination supports higher metal removal rates, longer tool life and consistent part quality in everyday workshop use.

FAQ

Which materials is this insert best suited for?
The CPMT090304 T5115 Tungaloy insert is optimised for machining cast iron, delivering improved wear resistance and stable cutting behaviour for grey and nodular cast irons.

What advantage does the T5115 grade provide?
The T5115 CVD-coated grade offers a balanced mix of wear resistance and edge stability, helping to extend tool life and maintain consistent cutting performance in cast-iron turning.

How is the insert secured in the holder?
The insert uses a cylindrical hole with a single-side countersink (40°–60°) for fixation; compatibility with ISO holders depends on form, free angle, tolerance class, fixation method, size and thickness.

Which cutting tasks suit the single-sided chipbreaker?
The single-sided chipbreaker controls chip formation for typical cast-iron chips, making it suitable for both external and internal turning where predictable chip control and evacuation are required.

What geometry details influence machining stability?
Key geometry features are the rhombic 09 form (80°), 0.4 mm corner radius and 11° clearance angle, together providing a stable cutting edge, good surface finish and repeatable performance.
