Iscar 3606515 Turning Toolholder Right Hand Mcrn

Product Description

The ISCAR 3606515 is a right-hand MCRN-style indexable turning toolholder from the Isoturn series, designed for external turning operations on CNC and manual lathes. It features a negative rake angle of -5 degrees and a 75-degree lead angle, making it suited for heavy-duty interrupted and continuous cuts where insert stability and edge strength are priorities. The 1 inch by 1 inch square shank provides rigid clamping in standard toolpost and turret setups. Insert retention uses a combination clamp-and-pin method, which secures CN..43.. series inserts firmly under high cutting loads. Coolant-through capability is not included on this holder.

This toolholder is built for turning applications in production and job-shop environments, including OD turning of ferrous and non-ferrous materials on turret lathes, engine lathes, and machining centers with live tooling. It accepts CN..43.. inserts, with the compatible insert size code CNMG431-GN confirmed for this holder. The right-hand cutting direction suits standard spindle rotation for the majority of lathe setups. Overall holder length is 6 inches, and the head length is 1.25 inches, fitting most standard 1 inch shank toolpost positions.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the machine is in an energy-isolated state before changing inserts or mounting the toolholder. Secure the shank in a 1 inch toolpost, turret block, or boring bar holder to the toolpost manufacturer torque specification. Inspect insert seat and clamping pin for wear before seating a new insert.
