High productivity for cast iron with a cost-conscious carbide grade

The CVD-coated grade T515 is formulated for the economical machining of cast iron, delivering a balance of wear resistance and edge stability. Using a CVD coating over a cemented carbide substrate increases thermal resilience and reduces flank wear during continuous cutting, which supports longer tool life and fewer insert changes. For process planning, the thermal and tribological properties of the coating enable higher material removal rates on stable setups, so cycle times and per-part machining costs can be reduced without compromising component quality.

ISO compatibility and secure clamping reduce setup risk

Marked as an ISO CCMT insert, compatibility with a toolholder is governed by form, relief angle, tolerance class, fastening method, nominal size and plate thickness. The designation CCMT09T308 identifies geometry and tolerance so toolrooms can check holder fit quickly and avoid mis-matching. The 7° clearance angle and standardised dimensions ensure repeatable clamping and predictable cutting engagement, which contributes to stable cutting forces and consistent surface finish across batches. Further cutting data and holder recommendations are available from Metav Werkzeuge to support integration into existing tool systems.

Controlled chip formation and predictable edge life for reliable turning

The insert’s rhombic shape combined with a one-sided chipbreaker promotes efficient chip control during both external and internal operations. A 0.8 mm corner radius provides a compromise between edge strength and surface finish, permitting modest depth of cut increases while protecting the cutting edge from shock in interrupted cuts. The central cylindrical hole with a single-side countersink (40°–60°) allows secure screw clamping and simple replacement procedures, reducing machine downtime. These design aspects translate into reproducible part tolerances and reduced process variation in daily production.

FAQ

What materials is this insert best suited for?
This insert is optimised for cast iron machining; the T515 CVD-coated carbide grade and the insert geometry provide reliable performance on a broad range of grey and ductile cast irons.

How does the CCMT geometry affect holder compatibility?
The CCMT09T308 ISO designation defines form, size and thickness so that compatibility depends on matching holder form, fastening style, tolerance class and plate thickness for secure clamping.

What benefits does the CVD coating provide?
The CVD-coated surface increases thermal resistance and wear protection on the cutting edge, which helps maintain dimensional accuracy and extends edge life in continuous turning operations.

Can this insert tolerate interrupted cuts?
The 0.8 mm corner radius and robust carbide substrate offer improved edge strength that tolerates light to moderate interrupted cutting; selection of chipbreaker and cutting parameters should match the application and machine rigidity.

Is the insert suitable for internal and external turning?
Yes; the rhombic shape and single-sided chipbreaker make the insert versatile for both external and internal turning when used with the appropriate holder and cutting data.
