Sandvik Coromant 6398175 Cutoff Insert 3mm Corocut Qd

Product Description

The SANDVIK COROMANT 6398175 is a solid carbide cutoff and grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. It belongs to the CoroCut QD series and features a 3.00 mm cutting width (0.1181 inches) with a PVD-applied TiCN/Al2O3/TiN multilayer coating for wear resistance and extended tool life. The insert uses a clamp-style holding method, carries a neutral hand orientation, and is manufactured to a 7-degree relief angle. Grade 1135 is suited to a range of workpiece materials. A CF chipbreaker geometry controls chip flow during grooving and parting cuts. Licensed machinists and CNC tooling technicians are the primary installers.

This insert is designed for grooving and parting applications in precision turning environments. The CoroCut QD series is commonly used in production machining settings where consistent groove width and surface finish are required. The 3.00 mm cutting width and 0.15 mm corner radius (0.0059 inches) make this insert appropriate for shallow to medium-depth groove profiles. The CF chipbreaker geometry is optimized for finishing and light cutting conditions. This insert is sold individually but carries a minimum order quantity of 10 units per order.

Key Features

• Solid carbide construction with PVD-applied TiCN/Al2O3/TiN multilayer coating for wear and heat resistance
• 3.00 mm cutting width (0.1181 inches) with a width tolerance of 0.001969 inches for dimensional consistency
• CF chipbreaker geometry designed for controlled chip evacuation during grooving and parting
• 7-degree relief angle and 0.15 mm corner radius (0.0059 inches) for clean groove profiles
• Clamp-style insert holding method for secure, repeatable seating in compatible QD toolholders
• Neutral hand orientation for flexible application in standard turning setups

Compatibility

Designed for use with CoroCut QD series toolholders that accept G-seat, QD-style inserts. Confirm toolholder seat size G compatibility before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC tooling technician with the machine powered down and the spindle locked. Use the appropriate clamp key or torx wrench specified for the CoroCut QD toolholder to seat and secure the insert without over-torquing the clamp. Inspect the insert pocket and clamp for wear or debris before seating a new insert. Handle carbide inserts carefully to avoid chipping the cutting edge prior to use.
