Sandvik Coromant 5749455 Turning Toolholder Sdjcr

Product Description

The SANDVIK COROMANT 5749455 is a right-hand indexable turning toolholder with SDJCR style geometry, designed for external turning and facing operations on CNC and manual lathes. It accepts DCMT 32.52 inserts secured by a screw clamping method, providing rigid, repeatable insert positioning. The shank measures 16 millimeters wide by 16 millimeters high (0.6299 inches square), with an overall length of 4.9213 inches. The neutral rake angle (0 degrees) makes it a versatile choice for general-purpose turning across a wide range of workpiece materials. Machining professionals and tool-crib technicians specify this holder for its CoroTurn 107 series compatibility and multi-use flexibility.

This toolholder is suited for facing and turning operations in production and job-shop environments, both light and moderate-duty. The SDJCR style and right-hand orientation position it for standard external lathe work on conventional turrets and gang-tool setups. Its 16x16 millimeter square shank fits common tool block and quick-change toolpost systems used in CNC turning centers and manual engine lathes. The 20 millimeter (0.7874 inch) head length provides adequate clearance geometry for typical facing passes.
