Iscar 3601897 Indexable Turning Toolholder Crgn

Product Description

The ISCAR 3601897 is a right-hand indexable turning toolholder in the CRGN style, designed for negative-rake turning and facing operations on CNC and manual lathes. It accepts RNG 45 inserts and secures them with a top-clamp holding method, providing rigid clamping force suited for interrupted and continuous cuts. The shank measures 1 inch wide by 1 inch tall, with an overall length of 6 inches and a head length of 1.1 inches. The back-of-bar to cutting edge dimension is 1.25 inches. Part of the Isoturn series, this toolholder is installed by machinists and tool-room technicians working in production turning environments.

This toolholder is built for facing and turning applications on right-hand cutting setups. The negative rake geometry at -6 degrees suits harder workpiece materials and heavier depths of cut where insert strength is a priority. It does not include coolant-through capability, making it appropriate for external turning stations where flood or mist coolant is delivered externally. The CRGN style and RNG 45 insert compatibility position it within a widely used insert family across production and job-shop lathe work.

Installation Notes

Installation is performed by a qualified machinist or tool-room technician. Power down and lock out the lathe spindle before mounting or indexing inserts or seating the toolholder in the turret or tool post. Verify insert seating and clamp screw engagement before resuming operation. Do not exceed the insert manufacturer's recommended depth of cut or feed rate for the selected RNG 45 insert grade.
