Sandvik Coromant 5741218 Grooving Insert Corocut 1-2 3mm

Product Description

The SANDVIK COROMANT 5741218 is a solid carbide grooving insert in the CoroCut 1-2 series, designed for external grooving and parting operations on CNC lathes and turning centers. It features a 3 mm cutting width, a 5 mm maximum depth of cut, and a TiAlN plus AlCr2O3 PVD coating for heat and wear resistance at elevated cutting speeds. The insert carries a right-hand orientation, a neutral rake angle of 7 degrees, and a GS chip breaker geometry. ISO code RG123H1-0300-0002-GS1115 corresponds to manufacturer grade 1115. Machinists and CNC turning specialists install this insert in compatible CoroCut 1-2 toolholders for precise groove profiling on ferrous and non-ferrous workpieces.

This insert is suited for grooving applications in both production and job-shop turning environments. The HX insert seat size and 90-degree lead angle make it appropriate for straight-wall groove profiles. The GS chip breaker is optimized for controlling chip flow in medium-duty grooving passes. Applications include external groove turning on steel, stainless steel, and cast iron components where consistent groove width and depth control are required. The multi-use designation indicates the insert can be indexed for additional cutting edges during its service life.

Key Features

• Solid carbide substrate with TiAlN and AlCr2O3 PVD coating for extended tool life in demanding grooving operations
• 3 mm cutting width with a 5 mm maximum depth of cut for precise, narrow groove profiles
• GS chip breaker geometry for controlled chip evacuation during grooving passes
• Neutral rake with 7-degree rake angle suits a broad range of workpiece materials
• Right-hand orientation, HX insert seat, 90-degree lead angle for straight-wall grooves
• Multi-use insert — can be indexed to extend usable cutting edges per insert

Compatibility

Designed for use with SANDVIK COROMANT CoroCut 1-2 series toolholders that accept HX seat size inserts. ISO code RG123H1-0300-0002-GS1115 identifies the exact toolholder and seat pairing required. Verify toolholder designation against the CoroCut 1-2 system catalog before installation.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine before changing inserts, and confirm the spindle is fully stopped before accessing the turret. Use the correct Torx or hex key as specified by the toolholder manufacturer to seat the insert firmly without over-driving the clamping screw. Inspect the insert seat for chips or debris before seating the new insert to ensure proper contact and repeatable tool height.
