Sandvik Coromant 5741495 Cutoff Insert 3mm Corocut 1-2

Product Description

The SANDVIK COROMANT 5741495 is a solid carbide cutoff and grooving insert designed for parting and grooving operations on CNC lathes and turning centers. It belongs to the CoroCut 1-2 series and features a 3.00 mm cutting width with a right-hand lead angle of 5 degrees. The insert is manufactured from solid carbide in grade 1145 and carries a PVD-applied TiAlN and AlCr2O3 coating for wear resistance and thermal stability. A clamp-style holding method secures the insert in compatible toolholders. Maximum depth of cut reaches 18.80 mm, making it suitable for moderate-depth parting on bar stock and turned components. Licensed machinists and CNC operators install this insert as part of routine tooling maintenance.

This insert is suited for production turning environments requiring consistent, repeatable parting and grooving cuts. The CoroCut 1-2 series is a widely used platform in both job-shop and high-volume production settings, covering a range of workpiece materials. The 5-degree right-hand lead angle and 0.30 mm corner radius support controlled chip formation during cutoff operations. The CR chipbreaker geometry is matched to applications where chip control is a priority. Typical installation occurs in CNC turning centers equipped with CoroCut 1-2 compatible toolholders and insert seats sized for the G seat designation.

Key Features

• Solid carbide construction in manufacturer grade 1145 for consistent edge integrity
• PVD coating with TiAlN and AlCr2O3 layers for elevated wear and heat resistance
• 3.00 mm cutting width (0.1181 inches) with a maximum depth of cut of 18.80 mm (0.7402 inches)
• Right-hand lead angle at 5 degrees with a 0.30 mm corner radius for controlled entry
• CR chipbreaker geometry promotes reliable chip evacuation during parting operations
• Clamp-style insert holding method for secure, repeatable seating in compatible holders

Compatibility

Designed for use with CoroCut 1-2 series toolholders that accept a G insert seat size. The insert style is R123x2. Confirm holder compatibility using the manufacturers catalog number R123G2-0300-0503-CR 1145 when cross-referencing toolholder documentation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be stopped and all axis motion halted before changing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer to set clamping torque — do not overtighten the clamp screw. Inspect the insert seat and clamp for chips or debris before seating the new insert to ensure proper contact and edge alignment.
