Sandvik RF123H051-16BM Grooving Cut-Off Tool Holder

Sandvik Coromant RF123H051-16BM is an external grooving and cut-off toolholder in the CoroCut 1-2 family, designed to accept N123H2-0400-CM inserts for parting and grooving on turning centers. It features a 1 in. by 1 in. square shank (shank height 25.4 mm) and a right-hand cutting direction, with an overall length of 5 in (127 mm). The toolholder uses a screw-clamp retention system and is manufactured in steel for rigidity and accuracy in high-torque operations. It provides a maximum depth of cut of 0.51 in (13 mm), enabling precise grooving or parting on external diameters, with compatibility to CoroCut 1-2 insert interfaces and an external, 1-2 insert seat design. Applications include parting-off and grooving on small- to mid-diameter workpieces in general turning, where clean faces and controlled depth of cut are required across industries such as automotive, aerospace, and general engineering turning.
