High-efficiency machining for cast iron components

The CVD-coated carbide composition of the insert delivers a balance between wear resistance and toughness, making it particularly suitable for economical machining of cast iron. The T515 grade is engineered to maintain a stable edge when machining interrupted cuts or variable section workpieces, reducing the frequency of index changes and supporting longer machining cycles. In practice, this results in fewer tool interventions and a more predictable production rhythm, improving part throughput without sacrificing surface integrity.

Geometry and edge strength that support repeatable production

The trigon form combined with a 1.2 mm corner radius and a 4.76 mm plate thickness provides a robust cutting edge that tolerates modest tool overhang and cutting forces. The TH chipbreaker promotes controlled chip formation, reducing the risk of chip entanglement and improving surface consistency on turned faces. With a 0° relief angle and a cylindrical mounting hole, the insert affords secure clamping and repeatable seating, which benefits batch production by ensuring constant cutting geometry from one index to the next.

ISO system compatibility and application guidance

As part of an ISO insert system, compatibility with the toolholder depends on form, relief angle, tolerance class, clamping method, size and thickness. The recommended system build comprises the ISO turning insert, a matching external holder or boring bar, a support shim/clamp set and replacement screws as required. Typical uses include both external and internal turning; selection of the chipbreaker and T515 grade should follow the workpiece stability, cutting speed and interruption characteristics to maximise tool life and process reliability.

Process reliability, surface quality and cost-effectiveness

Using a CVD-coated carbide insert with a dedicated chipbreaker yields tangible process benefits: reliable chip control, consistent cutting forces and improved surface finish on cast-iron components. The insert’s specification supports a pragmatic trade-off between tool cost and performance, often resulting in lower overall machining costs per part due to extended index life and reduced downtime. For production environments seeking steady, repeatable results, this insert assists in maintaining cycle times and surface requirements with minimal setup complexity.
