High-performance PCD for faster, cleaner cuts

The PCD grade DX140 offers a combination of durability and thermal stability that enables significantly higher cutting speeds on soft and abrasive, non-ferrous materials. As a polycrystalline diamond option, the cutting layer resists abrasive wear and preserves edge geometry, which translates into fewer index changes and more productive machining cycles. This performance profile is particularly relevant where surface finish and dimensional stability on aluminium and similar alloys matter. The result is a predictable machining process with lower tooling consumption and improved throughput.

Multidirectional system design for flexible turning

The AddMultiTurn model series introduces a system approach: the insert, holder and clamping mechanism are matched for cutting in several directions with a single tool setup. This system reduces tool changes and simplifies tool inventory while maintaining process stability. The square plate and 90° edge orientation make it suitable for both longitudinal and profile operations, allowing a single tool to cover multiple tasks. For workshops seeking to streamline tool management, this alignment of insert geometry and system design supports shorter setup times and consistent production results.

Geometry and edge preparation for consistent results

With a corner radius 0.8 mm and a plate thickness of 4.76 mm, the insert balances strength and cutting precision. The moderate radius improves load distribution at the cutting edge, reducing the risk of chipping during interrupted cuts or when handling variable cross-sections. A zero-degree clearance angle supports stable contact conditions and predictable chip formation when used with the designated chipbreaker. These design choices contribute to a longer effective edge life and consistent workpiece surfaces, particularly in repetitive turning cycles.

Material compatibility and application recommendations

Engineered for machining aluminium, other non‑ferrous metals and abrasive non-metallics, the carbide-backed indexable insert with a PCD layer excels where abrasive wear and the need for excellent surface finish coincide. Typical applications include finishing and semi-finishing of profiles, facing operations and long-axis turning where high feed rates and reduced secondary operations are desired. For optimal results, match the insert to holders from the AddMultiTurn range and adjust speeds to exploit the DX140 grade’s high-speed capability while ensuring coolant and chip evacuation suit the workpiece material.
