Stable chip control for uninterrupted production

The combination of a single-sided chipbreaker and Tungaloy J740 cutting material is engineered to provide predictable chip formation and reduced edge chipping. The chipbreaker geometry helps evacuate swarf efficiently in many turning scenarios, which lowers the risk of workpiece damage and tool-induced vibration. For operations requiring steady metal removal rates, the insert’s design contributes to steady cycle times and less frequent insert changes, supporting higher overall productivity.

Geometry that supports consistent surface quality

A rhombic 55° geometry with a corner radius of 0.2 mm and a 7° relief angle provides a controlled cutting edge that reduces deflection on slender parts and small-diameter features. The moderate corner radius helps to improve component finish while limiting cutting forces, making the insert well suited to precision external and internal turning tasks. The 3.97 mm plate thickness adds rigidity at the cutting edge, improving repeatability across batches and maintaining dimensional accuracy.

Simple integration into ISO turning systems

Mounting compatibility is simplified by the ISO-standard form and the cylindrical hole with a one-sided countersink (40°–60°). Compatibility with a holder is determined by the insert form, relief angle, tolerance class, fastening method, size and thickness; matching these parameters ensures secure seating and repeatable clamping. The rhombic form and hole style make the insert suitable for common external holders and boring bars that accept ISO indexable plates with equivalent specifications.

Versatile use and selection guidance

Engineered for turning, the insert performs in both external and internal operations when paired with an appropriate holder and machining parameters. The carbide substrate and the J740 grade are selected to combine wear resistance and adequate toughness for stable cutting; however, optimal results require choosing a chipbreaker and cutting data matched to the workpiece material and machine rigidity. The insert fits into modular systems consisting of the plate, a matching external holder or boring bar, and the necessary clamp set and screws, allowing straightforward replacement and inventory management.
