Product Description

The SANDVIK COROMANT 5740804 is an indexable grooving and cutoff toolholder designated RF123F079-16B, part of the CoroCut 1-2 series. It is designed for external grooving, parting, and cut-off operations on CNC lathes and turning centers. The toolholder accepts N123F2-0250-CM inserts and uses a clamp-style insert holding method for secure, repeatable edge positioning. It handles a groove width range of 2.39 to 3.18 mm and a maximum depth of cut of 20.07 mm (0.79 inches). The shank measures 1 x 1 inches in cross-section with an overall length of 152.40 mm (5.999 inches). Machinists and CNC operators in precision machining, job shop, and production turning environments install this toolholder.

This toolholder is suited for external grooving and parting applications on ferrous and non-ferrous workpieces in both production and job shop turning environments. It is configured for right-hand operation and is compatible with standard 1-inch square shank tool blocks and quick-change tooling systems that accommodate that shank profile. The CoroCut 1-2 series is commonly used in applications requiring clean groove walls and controlled chip evacuation. No coolant-through capability is present on this holder. It is appropriate for use on manual turret lathes and CNC turning centers where the insert size code N123F2 is the specified platform.
