Sandvik Coromant 5749435 Indexable Turning Toolholder

Product Description

The SANDVIK COROMANT 5749435 is a right-hand indexable turning toolholder in the SDJCR style, designed for precision facing operations on CNC lathes and manual turning centers. It features a 3/4 x 3/4 inch square shank and an overall length of 4.5 inches, making it a compact, rigid platform for external turning work. The screw-clamp insert holding method secures DCMT 32.52 inserts with a neutral rake angle, providing consistent edge positioning and repeatable tool life. Machinists and tool crib supervisors in production and job-shop environments will recognize this holder as part of the CoroTurn 107 series tooling system.

This toolholder is suited for facing applications in both production and general-purpose turning environments. It accepts DCMT 32.52 inserts with a 3/8 inch inscribed circle, making it appropriate for light to medium material removal on small to mid-size workpieces. The right-hand orientation fits standard OD turning setups. Its multi-use designation means it can serve across multiple material types and part geometries without requiring a dedicated holder for each application.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the turret or tool post is de-energized before mounting or indexing the holder. Use the appropriate torque wrench and screw driver bit specified for the insert clamping screw to avoid stripping the clamp screw or damaging the insert seat. Verify shank clamping length meets machine tool manufacturer minimums before running at operating speeds.
