Sandvik Coromant 5735918 Cutoff Insert 4mm Carbide

Product Description

The SANDVIK COROMANT 5735918 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Built to the CoroCut 1-2 series specification, it features a 4.00 mm cutting width, a neutral hand orientation, and a CM chipbreaker geometry. The insert is held by a clamp-style toolholder and carries a TiAlN coating applied through a PVD process, which provides wear resistance at elevated cutting temperatures. Machinists and CNC operators use this insert for precision cutoff work where consistent chip control and dimensional accuracy are required.

This insert fits standard CoroCut 1-2 clamp-style toolholders and is suited for parting and grooving in a wide range of materials on both conventional and CNC turning equipment. The CM chipbreaker geometry is well matched to general-purpose turning operations including cutoff on low to medium alloy steels and stainless. The neutral lead angle and 7-degree relief angle support stable entry and clean separation. The manufacturers catalog number for this insert is N123H1-0400-0002-CM 1125. Each unit is sold individually with a minimum order quantity of 10 pieces.

Key Features

• 4.00 mm cutting width suits standard parting and grooving applications
• CM chipbreaker geometry provides controlled chip formation across common work materials
• TiAlN coating via PVD process improves heat resistance and tool life
• Neutral hand insert works in left-hand and right-hand clamp toolholders
• 0-degree lead angle with 7-degree relief angle supports clean, stable cutoff
• 0.20 mm corner radius minimizes stress concentration at the cutting edge

Compatibility

Designed for use with SANDVIK COROMANT CoroCut 1-2 series clamp-style toolholders accepting insert seat size H and insert style N123x1.

Installation Notes

Installation and replacement of carbide inserts should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before accessing the toolholder. Use the correct torx or hex key specified by the toolholder manufacturer to secure the clamp; do not overtighten by hand estimation alone. Inspect the insert seat and clamp for wear or debris before seating a new insert.
