Sandvik Coromant 5757751 Indexable Insert Screw

Product Description

The SANDVIK COROMANT 5757751 is a replacement screw designed to secure indexable inserts in compatible toolholders. These screws are a critical fastening component in indexable cutting tool assemblies, holding the insert firmly in the pocket during turning, milling, or boring operations. A loose or damaged clamping screw can cause insert movement, poor surface finish, and premature tool failure. Weighing 0.25 pounds, this is a direct OEM-style replacement intended for machinists and tooling technicians maintaining cutting tool assemblies on the shop floor or in the tool crib.

This screw is specified for use with toolholders of style 434.90. It is suited for CNC machining centers, turning centers, and manual lathe applications where indexable insert tooling is standard. Tooling technicians and machinists performing insert changes or toolholder maintenance will use this screw as a like-for-like replacement when the original fastener is stripped, lost, or worn.

Installation Notes

Insert screw replacement is a routine tooling maintenance task performed by machinists and tooling technicians. Before replacing the screw, ensure the machine is powered down and the spindle is fully stopped. Use the correct Torx or hex key driver specified for the toolholder — using an incorrect driver can damage the screw head. Do not overtighten; follow the toolholder manufacturer's documented clamping procedure to avoid cracking the insert or stripping the screw threads.
