Sandvik Coromant 5749473 Indexable Turning Toolholder

Product Description

The SANDVIK COROMANT 5749473 is a right-hand indexable turning toolholder in the SDJCR style, designed for use with DCMT 32.52 inserts secured by a screw clamping method. It features a 0.5 x 0.5 inch steel shank and an overall length of 5 inches, making it a compact and rigid platform for external turning operations. The neutral rake angle (0 degrees) provides a balanced cutting geometry suitable for a wide range of workpiece materials. This toolholder is part of the CoroTurn 107 series and is installed by machinists and CNC lathe operators in production and job-shop environments.

This toolholder is suited for facing operations on CNC lathes and manual turning centers where DCMT-style inserts are specified. The 0.5 x 0.5 inch shank fits standard toolpost and turret positions commonly found on small to mid-size lathes. With an inscribed circle of 0.375 inches and a head length of 0.94 inches, it accommodates precise positioning close to the part. The multi-use designation means it can be used across a variety of turning applications beyond dedicated facing passes.

Installation Notes

Installation is performed by machinists on CNC or manual lathes — power down and lock out the spindle before changing toolholders or inserts. Seat the shank fully in the toolpost or turret block and torque the clamping screws evenly to manufacturer specification before test-cutting. Use only the specified DCMT 32.52 insert grade and geometry; do not substitute inserts with a different nose geometry or inscribed circle size. Inspect the insert pocket and screw threads for wear or chip buildup at each insert change.
