Sandvik Coromant 5741436 Cutoff Insert 2mm Corocut 1-2

Product Description

The SANDVIK COROMANT 5741436 is a solid carbide cutoff and grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. Manufactured to the R123E2-0200-1001-CS 1125 specification, it belongs to the CoroCut 1-2 series and features a 2 mm cutting width with a TiAlN PVD coating for extended tool life in demanding cutting conditions. The insert carries manufacturer grade 1125 and uses a clamp-style holding method. With a 10-degree right-hand lead angle and a 7-degree relief angle, it is suited for stable, chip-controlled parting and shallow grooving work performed by machinists and CNC toolroom technicians.

This insert is intended for right-hand cutoff and grooving applications on turning equipment where controlled chip formation is critical. The CS chipbreaker geometry promotes efficient chip evacuation in a range of workpiece materials. It is a single insert sold in a minimum order quantity of 10 units, making it appropriate for job shops and production environments that require consistent tooling inventory. Typical applications include external grooving, parting to center, and shallow profile grooving on small to medium diameter workpieces in ferrous and non-ferrous materials.

Key Features

• Solid carbide construction with TiAlN PVD coating for heat and wear resistance
• 2 mm cutting width with a maximum depth of cut of 19.40 mm (0.7638 inches)
• CS chipbreaker geometry for controlled chip formation during parting and grooving
• 10-degree right-hand lead angle with a 7-degree relief angle for stable cutting entry
• Corner radius of 0.10 mm (0.0039 inches) for precise groove geometry
• Clamp-style insert seat size E for secure tool holding during high-feed operations

Compatibility

Designed for use in CoroCut 1-2 series toolholders accepting insert seat size E, as specified by the manufacturer for the R123x2 insert style family.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician with the machine powered down and all axes at a safe rest position. Use the recommended torque-limiting screwdriver or clamp key specified for the CoroCut 1-2 toolholder to seat the insert securely without over-tightening. Inspect the insert seat for debris or damage before seating a new insert. Never attempt to re-sharpen or modify carbide inserts.
