Seco 02565602 Dwln Indexable Turning Toolholder 3/4 in Shank

Product Description

The SECO 02565602 is a right-hand DWLN-style indexable turning toolholder designed for external turning operations on CNC lathes and manual turning centers. It features a 0.75 inch square shank, an overall length of 4.5 inches, and a negative rake angle of -6 degrees, making it well suited for heavy interrupted cuts and hard-material turning. The clamp-lock insert holding method provides rigid, repeatable insert seating. This toolholder accepts WN..43. series inserts and is intended for installation by machinists and CNC operators in production and job-shop environments.

This toolholder is appropriate for a wide range of turning applications across universal workpiece materials, including steel, cast iron, stainless, non-ferrous alloys, high-temperature alloys, and plastics, corresponding to material groups H, K, M, N, P, and S. The 95-degree lead angle and right-hand cutting direction suit standard facing and longitudinal turning passes. The back-of-bar to cutting edge distance is 1.0 inch, which aids in tool offset setup during job changeover.

Installation Notes

Installation is performed by machinists or CNC setup technicians. The machine spindle must be fully stopped and the turret or tool block locked out before mounting or removing the toolholder.
