Sandvik Coromant 6656912 Grooving Insert Coromill Qd

Product Description

The SANDVIK COROMANT 6656912 is a solid carbide grooving insert designed for use in CoroMill QD series milling cutters. It carries a TiAlN coating applied via PVD process, providing wear resistance in demanding milling and grooving operations. The insert features a neutral hand orientation, a cutting width of 0.0787 inches (2.00 mm), and a cutting height of 0.1220 inches (3.10 mm). Grade 1040 solid carbide combined with the ML chip breaker geometry makes this insert well suited for stable, controlled grooving cuts. Installation and tooling changes are typically performed by CNC machinists or tool crib technicians on milling centers.

This insert fits CoroMill QD system toolholders and is intended for grooving and parting-style milling operations on machining centers in both production shop and job shop environments. The QD-N insert style with ISO code QD-NE-0200-020E-ML 1040 identifies the exact seat geometry and size. Insert seat size is E. It is packaged individually but carries a minimum order quantity of 10 units, making it appropriate for production tooling replenishment or initial setup of CoroMill QD tooling systems.

Key Features

• Solid carbide substrate with PVD-applied TiAlN coating for extended tool life
• ML chip breaker geometry for controlled chip formation during grooving
• Cutting width of 0.0787 inches (2.00 mm) for narrow-groove applications
• Neutral hand orientation for straightforward toolholder compatibility
• 7-degree rake angle supports positive cutting action
• Insert size E with ISO code QD-NE-0200-020E-ML 1040 for precise toolholder matching

Compatibility

Designed for use with CoroMill QD series toolholders accepting insert seat size E and insert style QD-N. ISO code QD-NE-0200-020E-ML 1040 should be referenced when selecting the correct toolholder and shim combination.

Installation Notes

Insert changes should be performed with the machine powered down and the spindle at a full stop. Use the correct torque wrench and insert key specified for the CoroMill QD toolholder to avoid seat damage or insert cracking. Inspect the insert seat and clamping components for wear or debris before seating a new insert. Follow the toolholder manufacturer guidelines for clamping sequence and verify runout after installation before resuming cuts.
