Sandvik Coromant 5741444 Cutoff Insert 4mm Corocut 1-2

Product Description

The SANDVIK COROMANT 5741444 is a solid carbide cutoff and grooving insert designed for precision parting, grooving, and profiling operations on CNC lathes and turning centers. It carries the R123H204000501CF designation and belongs to the CoroCut 1-2 series, engineered for reliable chip control and dimensional accuracy in high-volume turning applications. The insert features a 4.00 mm (0.1575 inch) cutting width, a 5-degree right-hand lead angle, and a CF chipbreaker geometry. A TiCN/Al2O3/TiN multilayer coating applied via MTCVD process provides wear resistance and thermal stability across a range of workpiece materials.

This insert is suited for use on production turning equipment where controlled chip evacuation is critical. The CoroCut 1-2 series is commonly applied in residential and industrial machining environments handling steel, stainless, and similar materials. Typical users include CNC machinists and toolroom professionals who require consistent parting depths up to 25.30 mm (0.9961 inch) and tight width tolerances. The CF chipbreaker geometry is optimized for finishing and light-to-medium grooving passes where surface finish and insert life are priorities.

Key Features

• Solid carbide substrate with MTCVD-applied TiCN/Al2O3/TiN multilayer coating for extended tool life
• 4.00 mm cutting width with a width tolerance of +0.004/-0 inch for precise groove sizing
• CF chipbreaker geometry promotes controlled chip formation during grooving and parting
• 5-degree right-hand lead angle suits standard right-hand turning setups
• Maximum depth of cut 25.30 mm (0.9961 inch) for deep-groove and parting applications
• Corner radius of 0.15 mm (0.0059 inch) for defined groove floor geometry

Compatibility

Designed for use in CoroCut 1-2 series toolholders and insert seats designated for H-size inserts with an R123H2 insert style. Verify toolholder seat size and clamping system compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or clamping screw torque as specified by the toolholder manufacturer - do not estimate. Inspect the insert seat for chips or debris before clamping to ensure proper seating and prevent premature insert failure.
