CPMT 09T308 T515 — indexable insert for turning (Tungaloy)

The CPMT 09T308 T515 is an ISO‑standard indexable turning insert designed for economical and productive machining of cast iron in external and internal turning applications.

• CVD-coated carbide grade T515
• Optimised for economical cast iron machining
• ISO form CPMT09T308 for broad holder compatibility
• Cylindrical hole with single‑side countersink

High productivity and predictable tool life for cast‑iron turning

The CVD‑coated carbide grade T515 delivers a balance of wear resistance and toughness that suits continuous production on cast iron components. This coating supports stable chip formation and a consistent cutting edge under varying cutting speeds, which contributes to longer tool life and fewer index changes. For workshops prioritising throughput and cost control, the insert’s geometry and coating enable repeatable performance in both finishing and semi‑roughing operations, while the single‑sided chipbreaker aids controlled chip flow and evacuation.

ISO conformity and system compatibility reduce setup guesswork

Designed to the ISO indexable insert system, compatibility with the toolholder is determined by the insert form, clearance angle, tolerance class, fastening method, size and thickness. The rhombic shape and 0.8 mm corner radius suit a range of turning profiles; the insert thickness of 3.97 mm and the 11° clearance angle are key dimensions to check against the chosen holder. The insert features a cylindrical hole with a one‑sided countersink (40°–60°), which matches many common clamping systems. For reliable assembly, pair the insert with a matching external holder or boring bar, a suitable shim/clamp set and the correct replacement screws.

Practical recommendations for shop floor application and process safety

This insert is optimised for external and internal turning of cast iron and performs best when the chipbreaker and grade are selected to match component rigidity and machining strategy. Use the single‑sided chipbreaker for consistent chip control in continuous cuts; consider stiffer setups and adjusted feeds for interrupted cuts. The 80° approach angle supports good surface finish and effective material removal in typical turning operations. If there is any uncertainty about the correct grade, chipbreaker or holder pairing, Metav Werkzeuge offers technical guidance and specification support to help integrate the insert into an efficient machining process.

FAQ

Which materials is this insert optimised for?
The Tungaloy CPMT09T308 T515 insert is optimised for economical machining of cast iron; the CVD‑coated T515 grade provides balanced wear resistance and toughness for stable results on grey and nodular cast irons.

How is compatibility with a toolholder ensured?
Compatibility depends on matching the insert form, clearance angle, tolerance class, fastening method, size and thickness to the holder specification; check the holder for support of the rhombic CPMT09T308 geometry and the 11° clearance angle.

What applications suit the insert best?
Typical applications are external and internal turning where chip control and predictable edge life are important; the one‑sided chipbreaker supports continuous cutting and helps maintain surface finish in production environments.

How should the insert be mounted and which accessories are required?
Mount the insert in a compatible external holder or boring bar using the appropriate shim/clamp set and replacement screws; the cylindrical hole with single‑side countersink (40°–60°) fits common clamping systems.

What are the key geometry specifications to consider for setup?
Important specs include the 0.8 mm corner radius, 3.97 mm thickness, 11° clearance angle, 80° approach angle and size 09; the SKU for ordering is 6747829‑Tungaloy.
