Sandvik Coromant 6427335 Cutoff Insert 2mm Carbide Tialn

Product Description

The SANDVIK COROMANT 6427335 is a carbide cutoff and grooving insert from the CoroCut QD series, designed for precision parting and grooving operations on CNC lathes and turning centers. It features a 2 mm cutting width and a TiAlN coating applied via PVD process, which provides thermal resistance and extended tool life in demanding cutting conditions. The neutral hand orientation and 7-degree relief angle support clean, controlled cuts, while the CO chipbreaker geometry manages chip flow during deep grooving and parting. This insert is installed and changed by machinists and toolroom technicians working in production or job-shop turning environments.

This insert is suited for grooving and parting applications in both light production and general-purpose turning setups. The CoroCut QD platform is built around rigid clamping and consistent edge positioning, making it a practical choice for interrupted cuts, face grooving, and parting-off on small to medium diameter workpieces. The clamp-style insert holding method ensures secure seating and repeatable positioning during high-cycle operations. Applications span ferrous and non-ferrous materials where a 2 mm slot width is required.

Key Features

• 2 mm cutting width with a width tolerance of 0.000787 inches for precise slot dimensions
• TiAlN PVD coating for heat resistance and extended edge life in dry or semi-dry cutting
• CO chipbreaker geometry engineered for controlled chip evacuation in grooving and parting
• 7-degree relief angle reduces rubbing and supports clean cut entry
• Neutral hand orientation allows use in standard right-hand and left-hand toolholders where applicable
• Clamp-style insert holding method provides rigid, repeatable seating in CoroCut QD toolholders

Compatibility

Designed for use with CoroCut QD series toolholders that accept size E insert seats. Verify toolholder insert seat size and clamping style before installation.

Installation Notes

Insert changes should be performed with the machine in a fully stopped and locked-out state per applicable OSHA and facility lockout/tagout procedures. Use the correct insert key or torx wrench specified for the CoroCut QD clamping system to avoid seat damage. Inspect the insert pocket and clamping surfaces for chips or debris before seating the new insert. Handle carbide inserts with care to avoid chipping cutting edges prior to use.
