Sandvik Coromant 5735899 Grooving Insert Solid Carbide

Product Description

The SANDVIK COROMANT 5735899 is a solid carbide grooving insert engineered for precision external and internal grooving operations on CNC lathes and turning centers. It carries a TiAlN coating applied via PVD process, which delivers high surface hardness and heat resistance during interrupted and continuous cuts. The insert has a cutting width of 0.125 inches (3.17 mm), a maximum depth of cut of 0.7087 inches (18 mm), and a neutral hand orientation. Grade 1125 is a fine-grain carbide grade suited to a broad range of workpiece materials. The GM chip breaker geometry promotes reliable chip control at moderate feed rates. Licensed machinists and CNC operators install this insert as a direct replacement or standard tooling component.

This insert is part of the CoroCut 1-2 series and is sized for insert seat size G. It fits toolholders designed for the N123 insert style within the CoroCut 1-2 platform. Typical applications include grooving, parting, and undercutting operations on ferrous and non-ferrous workpiece materials in production and job-shop environments. The ISO code N123G2-0318-0003-GM 1125 can be used to cross-reference compatible toolholders. The multi-use designation indicates suitability across a range of grooving depth requirements, with a maximum depth of cut range of 0.394 inches to 0.787 inches (10 mm to 20 mm).

Compatibility

Designed for use with CoroCut 1-2 series toolholders accepting insert style N123, insert seat size G. ISO code N123G2-0318-0003-GM 1125 identifies the exact insert-to-holder fit. Verify toolholder seat size and clamping configuration before installation.

Installation Notes

This insert is installed and replaced by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and clamping screw specified by the toolholder manufacturer — do not overtighten or use impact tools on the clamping screw. Inspect the insert seat for debris or damage before seating the new insert to ensure proper contact and runout.
