Seco 02565468 Indexable Turning Toolholder 95 Degree

Product Description

The SECO 02565468 is a DCLN-style indexable turning toolholder designed for right-hand cutting on CNC lathes and turning centers. It features a 95-degree lead angle, a negative rake geometry, and a clamp-lock insert holding method that secures CN-style inserts firmly under high cutting loads. The shank measures 1.25 x 1.25 inches with an overall length of 6 inches. This toolholder is intended for use by machinists and tooling technicians performing external turning operations across a wide range of workpiece materials.

This toolholder is suited for external turning in both production and job-shop environments where universal material compatibility is required. It accepts CN-style inserts with a 0.75-inch inscribed circle, making it compatible with a broad insert inventory. The 95-degree lead angle provides a slight back-cutting geometry that helps reduce axial cutting forces. Coolant-through capability is not included. Typical applications include straight turning, facing approaches, and finishing passes on materials spanning steel, cast iron, aluminum, non-ferrous alloys, and superalloys.

Compatibility

Compatible with CN-style inserts in the following designations: CBNN, CNGA, CNGP, CNMA, CNMG, CNMM, and CNMP, all with a 0.75-inch (3/4 inch) inscribed circle. Designed as a standard OEM-style external turning toolholder for use in 1.25 x 1.25 inch shank tool posts and turrets on CNC and manual lathes.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the lathe spindle is fully stopped and the machine is locked out before mounting or adjusting the toolholder in the turret or tool post. Torque the tool post clamping screws to the machine or turret manufacturer specifications. Verify insert seating and clamp screw engagement before initiating any cutting cycle.
