Sandvik Coromant 7690517 Corocut Qd Profiling Insert

Product Description

The SANDVIK COROMANT 7690517 is a CoroCut QD series profiling insert designed for precision grooving and profiling operations on CNC lathes and turning centers. Manufactured from carbide at manufacturer grade 1125 with a PVD-applied TiAlN coating, this insert delivers wear resistance and thermal stability during interrupted and continuous cuts. The neutral hand orientation and positive 20-degree rake angle support consistent chip formation. With a corner radius of 0.0788 inches (2.00 mm) and a maximum depth of cut of 0.0709 inches (1.80 mm), it suits fine profiling passes on tight-tolerance workpieces. A single cutting edge and clamp-style holding method ensure repeatable positioning. Machinists and CNC operators in job shops and production environments install this insert as part of a CoroCut QD tooling system.

This insert is intended for use on steel, stainless steel, superalloys, and titanium workpieces, corresponding to ISO material groups P, M, and S. Typical applications include profiling and turning operations where a small, precise insert with controlled depth capability is required. The RM chipbreaker geometry is suited to medium-to-finishing passes on the listed material families. The ISO code designation is QD-NH-0400-RM 1125, which identifies the insert within the CoroCut QD system for correct toolholder pairing.

Key Features

• Carbide substrate with PVD TiAlN coating for wear resistance on steel and superalloy workpieces
• Manufacturer grade 1125 optimized for ISO P, M, and S material groups
• Positive rake angle of 20 degrees with RM chipbreaker for reliable chip control
• Corner radius of 0.0788 inches (2.00 mm) supports profiling geometry accuracy
• Maximum depth of cut of 0.0709 inches (1.80 mm) for controlled finishing passes
• Neutral hand insert with clamp-style holding for secure, repeatable seating

Compatibility

Designed for use with SANDVIK COROMANT CoroCut QD toolholders accepting the QD-NH-0400-RM insert designation. Verify toolholder seat dimensions against the ISO code QD-NH-0400-RM 1125 before installation.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key as specified by the toolholder manufacturer to seat the clamp; do not use impact tools on insert clamps. Inspect the toolholder pocket and clamp for wear or debris before seating a new insert to ensure proper contact and prevent premature edge failure.
