It accepts N123G2-GM inserts and is engineered for right-hand cutting with a straight-mount shank. Key specifications include a 1.25-inch shank diameter, a maximum depth of cut of 0.3543 inches (9 millimeters), and a minimum groove width of 0.1181 inches (3 millimeters). Through-coolant capability supports extended tool life and chip evacuation in demanding bore-grooving applications. The toolholder is manufactured from steel and is suited for use by machinists and toolroom professionals working on precision internal grooving tasks.\u003c\/p\u003e\u003cp\u003eThis toolholder is intended for internal grooving of bores with a minimum bore diameter of 1.5748 inches (40 millimeters) and supports a maximum bore depth of 5 inches (127 millimeters). The maximum workpiece diameter is 1.25 inches (31.75 millimeters). It is applicable in production turning environments where consistent groove geometry and repeatability are required. The straight shank mount makes it compatible with standard toolholding systems used in CNC turning applications. The multi-use tool designation indicates it can support a range of grooving tasks within its dimensional envelope.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInternal non-face grooving toolholder in the Coro Cut 1-2 series\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design for improved chip control and insert life\u003c\/li\u003e\n\u003cli\u003eAccepts N123G2-GM indexable inserts with clamp-style insert holding\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.3543 inches (9 millimeters)\u003c\/li\u003e\n\u003cli\u003eGroove width range of 0.1181 to 0.1575 inches (3 to 4 millimeters)\u003c\/li\u003e\n\u003cli\u003eFull radius insert compatibility for smooth groove profiles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with N123G2-GM inserts (compatible insert size code N123G2) in internal non-face grooving applications.
