Sandvik Coromant 7937549 Grooving Insert Corocut Qi

Product Description

The SANDVIK COROMANT 7937549 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Built to the CoroCut QI system, it carries a 0.0787-inch cutting width with a neutral hand orientation and an 8-degree relief angle. The insert grade is 1125, a coated carbide formulation suited for steel and stainless steel workpieces. The GF chip breaker geometry promotes reliable chip control in continuous grooving passes. This insert is installed by machinists and CNC lathe operators in production and job-shop environments requiring consistent groove depth and width accuracy.

This insert is used in external grooving, face grooving, and parting applications on CNC turning equipment. It is configured for the CoroCut QI insert seat size E toolholding system and targets primary workpiece materials of steel, with secondary capability on stainless steel. Typical applications include groove-to-dimension cuts, snap-ring grooves, and undercut profiles in production turning environments. The neutral hand configuration suits standard right-hand and left-hand toolholder arrangements where the insert approach is centered on the workpiece.

Key Features

• 0.0787-inch cutting width for precision narrow-groove applications
• Solid carbide construction with manufacturer grade 1125 coated carbide
• GF chip breaker geometry for controlled chip evacuation in steel grooving
• 8-degree relief angle reduces cutting force and flank contact
• Neutral hand orientation compatible with centered grooving setups
• Single cutting edge design for consistent, repeatable groove geometry

Compatibility

Designed for use in CoroCut QI system toolholders with insert seat size E. Compatible with primary workpiece material steel and secondary workpiece material stainless steel. ISO code QI-NE-0200-0002-GF 1125 identifies the toolholder and seat pairing for this insert.

Installation Notes

This insert is installed by a qualified machinist or CNC lathe operator. Power down and lock out the spindle before changing inserts. Seat the insert fully into the QI pocket and verify clamping torque with the appropriate CoroCut QI wrench per the toolholder manufacturer's seating procedure. Inspect the insert seat for chips or contamination before installation to prevent seating errors that affect groove width accuracy.
