Iscar 3602637 Dcln Turning Toolholder Right Hand 1.25in

Product Description

The ISCAR 3602637 is a right-hand DCLN-style indexable turning toolholder in the Isoturn series, designed for external turning operations on CNC and manual lathes. It accepts CN..43. series inserts secured by a top clamp, providing a stable, negative-rake cutting geometry with a -6-degree rake angle and a 95-degree lead angle. The 1.25 inch by 1.25 inch square shank measures 6 inches in overall length with a 1.5 inch head length. This toolholder is installed by machinists and toolroom technicians performing general-purpose turning on ferrous and non-ferrous materials.

The 3602637 is suited for right-hand cutting operations in production turning environments, including roughing and finishing passes where a negative-rake insert provides edge strength and predictable chip control. The Isoturn platform and ISO 13399 compliance make it compatible with standard toolholder presetting equipment and digital tool management systems. It is a single-use (non-multi-use) toolholder intended for dedicated lathe setups in job shops, production floors, and maintenance machining operations.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the lathe spindle before mounting or removing the toolholder from the turret or tool post. Ensure the shank seating surfaces are clean and free of chips before clamping to maintain proper tool height and alignment. Follow the machine tool manufacturer torque specifications for tool post or turret clamping fasteners — do not use values not supplied by the machine OEM.
