Sandvik Coromant 5735859 Corocut 1-2 Grooving Insert

Product Description

The SANDVIK COROMANT 5735859 is a solid carbide grooving insert designed for the CoroCut 1-2 system. Carrying ISO designation N123F2-0318-RO H13A, this insert features a neutral hand orientation and an uncoated bright finish. It delivers a cutting width of 0.125 inches (3.17 mm) and a maximum depth of cut of 0.732 inches (18.60 mm), with a depth-of-cut range spanning 0.300 to 1.000 inches (10.00 to 20.00 mm). The corner radius measures 0.0625 inches (1.58 mm), and the rake is positive. This insert is installed by machinists and tooling technicians on CNC lathes and turning centers equipped with CoroCut 1-2 compatible toolholders.

This insert is suited for grooving, parting, and profiling operations on turning equipment. The F2 insert size and RO chip breaker geometry make it appropriate for a range of workpiece materials where an uncoated carbide substrate is preferred, such as cast iron and certain non-ferrous applications. The neutral hand designation allows use in standard radial grooving setups. It is packaged individually and sold in multiples of 10, making it a standard replenishment item for shops running CoroCut 1-2 toolholding systems.

Key Features

• Solid carbide substrate with bright uncoated finish for compatibility with a broad range of workpiece materials
• Cutting width of 0.125 inches (3.17 mm) for precise groove sizing
• Maximum depth of cut of 0.732 inches (18.60 mm) supports deeper grooving applications
• Positive rake geometry via RO chip breaker promotes efficient chip evacuation
• Corner radius of 0.0625 inches (1.58 mm) reduces stress concentration at groove root
• Multi-use insert designation allows use across compatible CoroCut 1-2 holders and seats

Compatibility

Designed for use with SANDVIK COROMANT CoroCut 1-2 series toolholders using an F insert seat size. ISO code N123F2-0318-RO H13A identifies the exact holder and seat interface required.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine fully powered down and in a safe, locked-out state. Seat the insert fully into the F-size pocket of the compatible CoroCut 1-2 holder before engaging the clamping screw. Inspect the insert seat for chips or debris prior to seating, as contamination can affect insert registration and tool life. Follow the toolholder manufacturer's torque guidelines for the clamping screw; do not over-torque.
