Seco 02565596 Dwln Indexable Turning Toolholder 1in Shank

Product Description

The SECO 02565596 is a right-hand DWLN-style indexable turning toolholder built for external turning operations on CNC and manual lathes. It features a 1 inch by 1 inch square shank and an overall length of 6 inches, with a negative rake angle of -6 degrees and a 95-degree lead angle. The holder uses a clamp-lock insert retention method and accepts WN-style inserts with a 3/8 inch inscribed circle. The steel body is manufactured to OEM-grade tolerances, making it a direct fit for production and job-shop turning applications. Installation is performed by licensed machinists and CNC setup technicians.

This toolholder is suited for external turning on a broad range of workpiece materials, including steels, cast irons, stainless alloys, non-ferrous metals, high-temperature alloys, and general-purpose materials corresponding to ISO material groups H, K, M, N, P, and S. The DWLN geometry positions the insert at a 95-degree lead angle, which helps manage cutting forces and chip flow during right-hand turning cuts. It is a single-purpose turning tool and is not configured for multi-use or coolant-through applications.

Key Features

• DWLN toolholder style with 95-degree lead angle for controlled chip flow in external turning
• Negative rake angle of -6 degrees for increased insert edge strength on harder materials
• Clamp-lock insert retention method provides rigid, repeatable insert seating
• Accepts WN-series inserts: WNGA, WNGP, WNMA, WNMG, WNMM, and WNMP in size WN..33.
• 1 inch by 1 inch square shank with 6 inch overall length fits standard lathe tool blocks

Compatibility

Accepts WN-style indexable inserts with a 3/8 inch inscribed circle, specifically compatible insert designations WN..33.., WNGA, WNGP, WNMA, WNMG, WNMM, and WNMP. Designed as an OEM-style replacement toolholder for right-hand external turning setups using standard square-shank tool blocks.

Installation Notes

Installation and insert changes are performed by qualified machinists or CNC setup technicians. Power down and de-energize the machine and release any stored spindle energy before servicing the toolholder or changing inserts. Verify that the insert seat and clamp components are clean and free of chips before seating a new insert. Follow the machine tool manufacturer guidelines and applicable shop safety standards when torquing clamp screws.
