Sandvik Coromant 5918493 Grooving Insert Cbn Corocut 1-2

Product Description

The SANDVIK COROMANT 5918493 is a cubic boron nitride (CBN) grooving insert designed for precision grooving operations on hardened and difficult-to-machine materials. Part of the CoroCut 1-2 series, this insert carries manufacturer grade 7015 with a PVD-applied titanium nitride (TiN) coating. It features a neutral hand orientation, a 4 mm cutting width, and a maximum depth of cut of 0.65 mm. The insert measures approximately 0.99 inches in overall length and weighs 0.1 pounds. It is installed by machinists and toolroom technicians on CNC turning centers and grooving toolholders where tight tolerances on hardened workpieces are required.

This insert is suited for external grooving applications on hardened steels, cast irons, and superalloys where conventional carbide tooling reaches its limits. The CoroCut 1-2 platform is commonly used in production turning environments on both CNC lathes and multi-function machines. The neutral hand configuration allows flexible positioning in standard right- or left-hand toolholders within the CoroCut 1-2 system. Typical applications include finish grooving, parting, and profiling on hardened components in automotive, bearing, and aerospace part manufacturing.

Key Features

• Cubic boron nitride insert material for machining hardened and abrasion-resistant workpiece materials
• PVD titanium nitride (TiN) coating applied for improved wear resistance and edge integrity
• 4 mm cutting width with a maximum depth of cut of 0.65 mm
• 2 mm corner radius for controlled chip formation and surface finish
• Neutral hand orientation for versatile toolholder compatibility within the CoroCut 1-2 platform
• Manufacturer grade 7015 targeting finishing passes on hardened materials

Compatibility

Designed for use with SANDVIK COROMANT CoroCut 1-2 series toolholders and grooving systems that accept the N123 insert style in size 0400.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or replacing the insert. Use the correct torx or clamping key specified for the CoroCut 1-2 toolholder to secure the insert — do not overtighten with non-specified tools. Inspect the insert pocket and clamping seat for chips or debris before seating a new insert to ensure proper seating and repeatability.
