Sandvik Coromant 5763740 Compression Spring Indexable

Product Description

The SANDVIK COROMANT 5763740 is a compression spring designed for use in indexable toolholder assemblies. It functions as the internal clamping component that applies consistent seating pressure to hold cutting inserts securely in the pocket during turning, boring, and facing operations. This spring is a direct replacement part intended to restore proper clamping force when the original spring loses tension or fails. It is rated for toolholders accepting 12mm insert sizes and weighs 0.25 pounds. Installation is typically performed by CNC machinists or toolroom technicians during routine toolholder maintenance.

This compression spring fits indexable toolholder bodies used in turning and boring applications where 12mm inserts are specified. It is a maintenance replacement component suited for production environments where toolholders are regularly serviced rather than replaced as complete assemblies. Keeping spare springs on hand reduces downtime during insert changeovers when internal components show wear or fatigue.

Key Features

• Compression spring type provides consistent seating load against indexable insert pockets
• Sized for toolholders with 12mm tool holder insert dimension
• Direct OEM-style replacement to restore factory clamping performance
• Lightweight at 0.25 pounds for easy handling during toolholder teardown
• Sold individually — single-unit packaging supports targeted maintenance without over-ordering

Compatibility

Designed as an OEM-style replacement compression spring for SANDVIK COROMANT indexable toolholders accepting a 12mm insert dimension. Confirm the specific toolholder model designation before ordering to ensure correct spring fitment.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel during toolholder disassembly and maintenance. Always remove the toolholder from the machine spindle and ensure all clamping screws are fully backed out before disassembling the insert pocket. Use appropriate driver bits specified for the toolholder clamping screw to avoid stripping. Inspect the insert pocket seat and clamping screw for wear before reassembly to confirm the new spring will seat correctly.
