Seco 02569286 Rh Dwln Indexable Turning Toolholder 1 in

Product Description

The SECO 02569286 is a right-hand DWLN-style indexable turning toolholder designed for use on CNC and manual lathes in metal-cutting operations. It features a negative rake angle of -6 degrees and a 95-degree lead angle, characteristics that promote stable cutting and longer insert life when working across a broad range of workpiece materials. The toolholder accepts WNMG 432 inserts secured by a dual clamp holding method, providing rigid insert retention during heavy-duty turning passes. The square shank measures 1 inch wide by 1 inch tall with an overall length of 6 inches, making it a standard fit for most tool turrets and boring bar holders used in production turning environments.

This toolholder is intended for universal turning applications across ferrous and non-ferrous workpiece materials, including cast iron, aluminum, carbon steel, stainless steel, high-temperature alloys, and non-metallic materials as indicated by material codes H, K, M, N, P, and S. It is suited for both roughing and finishing passes where negative rake geometry provides edge strength and predictable chip control. Typical installation scenarios include production machining cells, job shop lathes, and CNC turning centers where WNMG 432 inserts are already in use. Coolant-through capability is not included on this holder.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the toolholder in the tool turret or tool post according to the machine manufacturer's torque and clamping specifications before operation. Ensure the insert seat and clamp surfaces are clean and free of chips before seating a new insert. Always bring the spindle to a complete stop and follow lockout/tagout procedures before changing inserts or repositioning the toolholder.
