Sandvik Coromant 7937629 Profiling Insert Corocut Qi

Product Description

The SANDVIK COROMANT 7937629 is a solid carbide profiling insert in the CoroCut QI series, designed for precision turning and profiling operations on CNC lathes and turning centers. This insert carries ISO code QI-NH-0400-RM 1125 and features a 0.0788 inch corner radius, a positive rake geometry, and a TiAlN PVD coating applied over grade 1125 carbide substrate. With an included angle of 360 degrees and a relief angle of 8 degrees, it is optimized for full-radius profiling passes where consistent edge geometry is critical. It ships as a single cutting edge insert held by clamp and is installed by machinists and CNC toolroom technicians.

This insert is suited for profiling and turning operations on steel, stainless steel, superalloys, titanium, and cast iron workpieces, covering ISO material groups P, M, S, and K. It fits standard CoroCut QI toolholders accepting the NH style seat. Typical applications include contour turning, groove profiling, and finish passes where a full-radius insert form is required. The RM chipbreaker geometry supports controlled chip evacuation across these material groups in production and job-shop environments.

Key Features

• Solid carbide grade 1125 with TiAlN PVD coating for extended tool life on steel and stainless steel
• 0.0788 inch corner radius and 360-degree included angle for full-radius profiling geometry
• Positive rake angle reduces cutting forces on difficult-to-machine materials including superalloys and titanium
• RM chipbreaker promotes chip control across ISO P, M, S, and K workpiece materials
• Clamp-held neutral-hand insert for secure, repeatable seating in CoroCut QI toolholders
• Single cutting edge design ensures precise edge presentation on each index

Compatibility

Designed for use in CoroCut QI series toolholders accepting the NH seat style, size code 0400. Compatible workpiece materials include steel, stainless steel, superalloys, titanium, and cast iron per ISO material codes P, M, S, and K.

Installation Notes

Installation is performed by a machinist or CNC toolroom technician. Shut down spindle rotation and verify the machine is in a safe, locked-out state before changing inserts. Seat the insert firmly against the toolholder pocket with the clamp torqued to the toolholder manufacturer specification. Inspect the seat and clamping surfaces for chips or debris before seating to prevent micromovement during cutting.
