Sandvik Coromant 7937578 Grooving Insert Corocut Qi

Product Description

The SANDVIK COROMANT 7937578 is a carbide grooving insert designed for precision parting and grooving operations on CNC turning centers and lathes. This neutral-hand insert belongs to the CoroCut QI series and carries manufacturer grade 1125, a PVD-coated carbide grade engineered for consistent performance on steel and stainless steel workpieces. With a cutting width of 0.0969 inches and a single cutting edge geometry, it delivers controlled chip formation through its GF chip breaker profile. Machinists and toolroom technicians install this insert into compatible CoroCut QI toolholders for internal grooving and face grooving applications.

The 7937578 is suited for internal grooving work on steel and stainless steel in both production and job-shop environments. The GF chip breaker is optimized for finishing cuts on these materials, supporting stable chip evacuation in tight bore conditions. Insert seat size F and ISO code QI-NF-0246-0002-GF 1125 identify the precise seat geometry required for correct seating in CoroCut QI-compatible holders. This insert is typically specified by CNC machinists and toolroom technicians working to tight dimensional tolerances on turned components.

Compatibility

Designed for use with CoroCut QI series toolholders that accept insert seat size F. Compatible primary workpiece material is steel; compatible secondary workpiece material is stainless steel. Refer to the ISO code QI-NF-0246-0002-GF 1125 when selecting a matching toolholder seat.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before changing inserts. Seat the insert fully and evenly into the CoroCut QI pocket and torque the clamping screw to the toolholder manufacturer's specified value using a calibrated torque wrench. Inspect the insert seat for chips or contamination before seating a new insert to prevent premature edge failure.
