Sandvik Coromant 5758490 Indexable Insert Screw

Product Description

The SANDVIK COROMANT 5758490 is an indexable insert clamping screw designed to secure cutting inserts in compatible toolholders used in turning, milling, and boring operations. This type of fastener is a critical retention component — it holds the indexable insert firmly against the toolholder pocket during machining, ensuring accurate seating and repeatable cutting geometry. Weighing 0.25 pounds, it ships as a single-piece unit. Installation and replacement are performed by machinists and tool-crib technicians as part of routine insert indexing or toolholder maintenance.

This screw is specified for use with the 3212 010 toolholder style, making it a direct-fit fastener for that toolholder family. It is suited to production machining environments where indexable tooling is standard practice, including CNC turning centers, machining centers, and manual lathes running SANDVIK COROMANT tooling systems. Replacing worn or damaged clamping screws at regular intervals is standard maintenance practice to prevent insert movement, chatter, and premature insert failure.

Compatibility

Specified for use with the 3212 010 toolholder style. Verify toolholder documentation before ordering to confirm correct screw thread, drive type, and head geometry for your specific holder.

Installation Notes

Indexable insert clamping screws are installed and removed by machinists using the appropriate Torx or hex key driver specified by the toolholder manufacturer — use only the correct drive tool to avoid cam-out and screw damage. Always power down and lock out the machine spindle before accessing the toolholder. Do not overtighten; follow the torque guidance provided in the SANDVIK COROMANT toolholder documentation for this holder style. Inspect the screw thread and drive recess at each insert change and replace the screw if wear or deformation is observed.
