Seco 02565461 Dcln Indexable Turning Toolholder 1-1/4 in

Product Description

The SECO 02565461 is a right-hand DCLN-style negative rake indexable turning toolholder designed for external turning operations on CNC and manual lathes. It features a 1.25-inch square shank (1.25 inches wide by 1.25 inches high) and an overall length of 6 inches. The clamp-lock insert holding method secures CN-style inserts firmly under cutting loads, and the negative rake geometry at -6 degrees suits harder workpiece materials and interrupted cuts. A lead angle of 95 degrees promotes stable entry and reduces chatter. Licensed machinists and CNC operators working in job shops, production machining, and maintenance turning will find this toolholder a direct-fit choice for general-purpose external turning.

This toolholder accepts CN..54. series inserts with a 5/8-inch inscribed circle and is suited for turning a broad range of workpiece materials, including steel, cast iron, stainless, aluminum, non-ferrous, and high-temperature alloys as indicated by the universal material codes H, K, M, N, P, and S. The clamp-lock design keeps insert seating consistent across tool changes, which supports repeatable dimensional output in production runs. It is a single-purpose turning toolholder and does not serve multi-use or boring applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the toolholder in the toolpost to the appropriate clamping torque per machine manufacturer specifications before seating an insert. Always power down and lock out the spindle before changing inserts or repositioning the toolholder. Verify insert seating and clamp engagement before resuming cutting operations.
