Sandvik Coromant 5735646 Grooving Insert Corocut 1-2

Product Description

The SANDVIK COROMANT 5735646 is a solid carbide grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. Part of the CoroCut 1-2 series, it features a TiAlN coating applied via PVD process, delivering heat and wear resistance in demanding cutting environments. The insert has a 2 mm cutting width and a maximum depth of cut of 19.2 mm, making it well suited for medium-depth grooving work. A positive rake geometry and the RO chip breaker promote controlled chip formation and reduced cutting forces. Machinists and toolroom technicians working with steel, stainless, and similar materials are the primary installers of this insert.

This insert is used in external grooving and parting applications on CNC turning equipment. The N123x2 insert style and E2 insert size fit standard CoroCut 1-2 toolholders designed for that seat size. It is appropriate for both production turning environments and job-shop applications where consistent groove geometry is required. The neutral hand orientation allows use in both conventional and secondary-operation setups without altering toolholder configuration.

Key Features

• Solid carbide substrate with PVD TiAlN coating for wear resistance in high-temperature cutting zones
• 2 mm cutting width with a maximum depth of cut ranging from 10 mm to 20 mm
• Positive rake geometry reduces cutting forces and heat generation at the cutting edge
• RO chip breaker promotes reliable chip control during grooving passes
• 1 mm corner radius supports groove profile accuracy and edge strength
• Neutral hand orientation for flexible toolholder compatibility within the CoroCut 1-2 system

Compatibility

Designed for use with CoroCut 1-2 series toolholders accepting an E seat size and the N123x2 insert style. ISO code for this insert is N123E2-0200-RO 1125. Manufacturer catalog number is N123E2-0200-RO 1125.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians familiar with indexable insert tooling. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully against the insert pocket locating surfaces and torque the clamping screw per the toolholder manufacturer specification. Inspect the insert seat for chips or debris before installation to prevent seating errors that affect groove depth accuracy.
