CCMT120404 T5115 CCMT ISO turning insert (rhombic, 7°) — Tungaloy

A CCMT120404 T5115 CCMT ISO turning insert engineered for external and internal turning, offering balanced wear resistance and robust edge stability

• CVD-coated carbide grade T5115
• ISO CCMT120404 rhombic insert
• Single-sided chipbreaker, 0.4 mm radius
• Cylindrical hole with 40°–60° countersink

Consistent performance for cast-iron turning

The CCMT120404 is specified with a CVD-coated carbide composition (grade T5115), which combines enhanced surface hardness from the coating with a tough substrate to resist chipping. This construction results in a favourable balance between wear resistance and edge stability, making the insert well suited to machining cast iron where stable chip formation and predictable flank wear are essential. The coating also improves thermal resistance during interrupted cuts, supporting higher productivity and reduced tool change frequency while maintaining part quality.

Reliable fit and straightforward clamping

Compatibility with a toolholder is determined by insert form, relief angle, tolerance class, fastening method, size and thickness; the rhombic CCMT geometry with a 7° relief ensures correct seating and orientation in standard ISO holders. The insert is supplied with a cylindrical hole plus a single-side countersink ( 40°–60° ), enabling secure clamping and consistent axial positioning. These features reduce set-up variability and simplify replacement, which contributes to shorter machine downtime and more reproducible machining results.

Durability that supports efficient production

With a corner radius of 0.4 mm and a plate thickness of 4.76 mm, the insert provides a stable cutting edge for finishing and light to medium roughing operations. The single-sided chipbreaker controls chips effectively for many turning scenarios, improving surface finish and reducing the risk of rework. The ISO-standard sizing and robust CVD carbide make the component an economical choice: predictable wear behaviour lowers scrap rates and helps to forecast tooling costs per part, supporting a steady production flow and consistent part tolerances.

FAQ

What materials is this insert designed for? The CCMT120404 T5115 insert is formulated for machining cast iron, the T5115 grade offering an optimised combination of wear resistance and edge strength for that material.

How does the insert secure in the holder? The insert features a cylindrical hole with a single-side countersink (40°–60°) to enable secure clamping in compatible ISO toolholders, ensuring correct seating and repeatable positioning.

What advantages does the CVD coating provide? A CVD-coated surface increases thermal and abrasive resistance of the cutting edge, improving tool life under intermittent cutting conditions and supporting higher cutting speeds where appropriate.

Which insert dimensions are critical for process planning? Key dimensions include the corner radius (0.4 mm), plate thickness (4.76 mm) and inscribed size (12 mm); these parameters influence cutting forces, surface finish and holder compatibility.

Is the chipbreaker suitable for finishing operations? Yes, the single-sided chipbreaker on this CCMT geometry is designed to control chips and help achieve consistent surface quality in light to medium turning tasks.
