Sandvik Coromant 5749512 Indexable Turning Toolholder

Product Description

The SANDVIK COROMANT 5749512 is a right-hand indexable turning toolholder in the CoroTurn 107 series, designed for external turning operations on CNC and manual lathes. It uses a screw clamping method to secure DCMT 07 02 04 inserts and features a neutral rake angle of 0 degrees, which suits a wide range of material types and cutting conditions. The toolholder style is SDJC, with a 3/8 inch square shank measuring 0.375 inches wide by 0.375 inches tall and an overall length of 5 inches. Constructed from steel, it delivers the rigidity required for consistent, repeatable turning work. Machinists and CNC operators working in production or job-shop environments are the primary installers.

This toolholder is suited for light to medium-duty external turning applications in both production and maintenance machining environments. The SDJCR062C-S designation indicates right-hand cutting direction with a 3/8 inch square shank profile, making it compatible with standard tool blocks and turrets that accept that shank size. The CoroTurn 107 series is intended for positive insert geometries in applications involving low cutting forces, making it well suited for finishing and semi-finishing passes on a variety of workpiece materials. The screw clamping system provides secure insert retention during interrupted cuts and continuous turning alike.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine fully powered down and the spindle locked before any tooling changes. Ensure the insert pocket and seating surfaces are clean and free of chips before securing the DCMT insert with the clamping screw. Follow the machine tool manufacturer's torque specifications for the clamping screw and verify tool projection and centerline height before running the first part. Inspect the insert and clamping hardware at regular intervals per your shop's tooling maintenance schedule.
