Iscar 3602587 Dwln Indexable Turning Toolholder 16mm

Product Description

The ISCAR 3602587 is a left-hand DWLN-style indexable turning toolholder from the Isoturn series, designed for external turning operations on CNC lathes and manual turning centers. It features a 16mm x 16mm square shank and a 95-degree lead angle with negative rake geometry. The screw-clamp insert holding method provides rigid, repeatable seating for WNM-style inserts. Overall length is 100mm (3.94 inches) with a head length of 26mm (1.02 inches). Licensed machinists and CNC operators install this holder in production and job-shop turning applications where left-hand cutting direction is required.

This toolholder is suited for left-hand external turning on ferrous and non-ferrous materials in both roughing and finishing passes. The 95-degree lead angle supports longitudinal turning with positive cutting force direction. It is a non-coolant-through design, making it appropriate for flood or mist coolant environments where through-spindle coolant is not available. The Isoturn series is built to ISO 13399 standards, supporting digital tool assembly and presetter integration in modern CNC workflows.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or removing the toolholder. Seat the shank fully in the tool block and torque the clamping screws according to the machine manufacturer's specifications for the block size. Insert clamping screw torque should follow ISCAR's published tooling guidelines for the WNM insert pocket.
