Sandvik Coromant 5740956 Grooving Cutoff Toolholder RF151.23

Product Description

The SANDVIK COROMANT 5740956 is an indexable grooving and cutoff toolholder in the T-Max Q-Cut series, designed for external grooving operations on CNC lathes and turning centers. It accepts N151.2-300-5E inserts secured by a clamp-style holding method, providing rigid and repeatable insert location. The toolholder supports a groove width range of 3 inches to 4.15 mm (0.1181 to 0.1634 inches) and delivers a maximum depth of cut of 19.99 mm (0.787 inches). The 1 x 1 inch shank fits standard square-shank tool blocks and quick-change turrets. This right-hand holder is suited to production turning environments where consistent groove geometry and reliable insert indexing are priorities.

This toolholder is intended for external grooving and parting-off applications in general metalcutting. It is appropriate for use in job shop and production turning environments on conventional or CNC lathes. The T-Max Q-Cut series is engineered for stable cutting performance during grooving and cutoff passes. The right-hand designation means cutting action occurs from right to left when viewed from the operator side of the machine. Machinists and CNC turning technicians are the primary installers of this toolholder.
