Sandvik Coromant 5740879 Grooving Cutoff Toolholder Corocut 1-2

Product Description

The SANDVIK COROMANT 5740879 is an indexable grooving and cutoff toolholder designed for external turning operations on CNC lathes and turning centers. Built to CoroCut 1-2 series standards, it accepts N123F2-0250-CM inserts held in place by a clamp-style insert holding method. The toolholder handles a groove width range of 0.094 to 0.125 inches and a maximum depth of cut of 0.400 inches. The 3/4 x 3/4 inch square shank provides a rigid, low-profile setup suitable for tight clearance applications. This tool is installed and set up by CNC machinists and toolroom technicians working in production or job-shop environments.

This toolholder is suited for external grooving, cutoff, and parting operations on a range of workpiece materials. The right-hand orientation makes it compatible with standard spindle-forward turning setups. The CoroCut 1-2 platform is commonly applied in both high-volume production and precision short-run machining. The overall length of 4.500 inches and a maximum overhang of 1.142 inches give operators predictable reach and stability when setting tool projection in the turret.

Key Features

• Groove width range of 0.094 to 0.125 inches suits common parting and grooving applications
• Maximum depth of cut of 0.400 inches for cutoff and deep grooving passes
• Clamp-style insert retention for secure, repeatable insert indexing
• 3/4 x 3/4 inch square shank fits standard lathe turret pockets
• Right-hand cut orientation for conventional spindle-forward operation

Compatibility

Compatible with N123F2-0250-CM inserts. This toolholder uses the RF123..B toolholder style and is part of the SANDVIK COROMANT CoroCut 1-2 series platform.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine before mounting the toolholder in the turret. Ensure the shank is fully seated and clamped to the tool block or turret station before indexing the turret or running the spindle. Verify tool overhang does not exceed the rated maximum of 1.142 inches to maintain rigidity and prevent chatter during grooving or parting operations.
