It accepts N123F2-0250-CM inserts secured by a clamp-style holding method, providing rigid insert clamping during interrupted and continuous cuts. The toolholder handles a groove width range of 2.39 to 3.18 mm and a maximum depth of cut of 17 mm, making it well suited for medium-range grooving and parting applications in production turning environments. The shank measures 16 mm x 16 mm with an overall length of 125 mm.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is intended for external turning operations in both high-volume production and job-shop settings. It mounts in standard square-shank tool stations on CNC turning centers and manual lathes with appropriately sized tool blocks. Typical applications include grooving for snap rings and O-ring grooves, face grooving, and full parting of bar stock. The CoroCut 1-2 platform is a modular system, and this holder is paired specifically with N123F2 series inserts. Coolant-through delivery is not supported on this model.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGroove width range of 2.39 to 3.18 mm for precise external grooving and parting\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 17 mm suitable for medium parting and deep groove operations\u003c\/li\u003e\n  \u003cli\u003eRight-hand orientation for standard OD turning station mounting\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding for rigid, repeatable insert positioning\u003c\/li\u003e\n  \u003cli\u003e16 mm x 16 mm square shank with 96.40 mm shank length for compact tool station fitment\u003c\/li\u003e\n  \u003cli\u003ePart of the CoroCut 1-2 modular platform, compatible with N123F2 insert series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with N123F2-0250-CM inserts.
