Sandvik Coromant 5733414 Grooving Cutoff Toolholder LF123G079-16B

Product Description

The SANDVIK COROMANT 5733414 is an indexable grooving and cutoff toolholder in the CoroCut 1-2 series, catalog style LF123G079-16B. Designed for external grooving, parting, and cut-off operations, it accepts N123G2-0300-CM inserts held in place by a clamp-style insert holding method. The toolholder is left-hand orientation and handles groove widths from 3 to 4 mm (0.1181 to 0.1575 inches) with a maximum depth of cut of 20.07 mm (0.79 inches). The 1 x 1 inch shank provides rigid support in standard square-shank toolholding setups on lathes and turning centers. Installed by machinists and CNC turning technicians in production and job-shop environments.

This toolholder is suited for external grooving and parting operations on CNC lathes and manual turning centers. It is intended for applications requiring precise groove width control in the 3 to 4 mm range with a maximum overhang of 0.88 inches. The CoroCut 1-2 series is a common platform in production turning environments where repeatable insert indexing and secure clamping are required. Coolant-through capability is not available on this holder, so external coolant delivery is required for heat-sensitive workpiece materials.
