Sandvik Coromant 5736398 Grooving Insert Corocut 3

Product Description

The SANDVIK COROMANT 5736398 is a solid carbide grooving insert designed for precision external grooving operations on CNC turning centers and lathes. Manufactured to the ISO code N123T3-0080-0000-GS 1125, this insert features a TiAlN coating applied via PVD process, delivering high hardness and thermal resistance at the cutting edge. The 0.80 mm cutting width and 1.80 mm maximum depth of cut make it well suited for fine, shallow grooving applications where dimensional accuracy is critical. It carries a neutral hand orientation with a 7-degree rake angle and GS chip breaker geometry. Machinists and CNC operators in production and job-shop environments are the primary installers.

This insert belongs to the CoroCut 3 series and is intended for grooving operations on metallic workpieces in both production turning and precision component manufacturing. The GS chip breaker geometry promotes controlled chip formation in a range of materials. The T-size insert seat and overall length of 0.4094 inches allow direct fitment into compatible CoroCut 3 toolholders. Applications include grooving on shafts, hydraulic components, automotive parts, and precision turned parts where narrow groove widths are required.

Key Features

• Solid carbide substrate with PVD-applied TiAlN coating for extended tool life and heat resistance
• 0.80 mm cutting width with a maximum depth of cut of 1.80 mm for fine, controlled grooving
• Neutral hand orientation with 7-degree rake angle suits a broad range of turning setups
• GS chip breaker geometry promotes efficient chip evacuation in shallow grooving cuts
• CoroCut 3 series insert for use with compatible T-seat toolholders
• Multi-use tool designation supports versatile application across compatible holding systems

Compatibility

Designed for use with CoroCut 3 series toolholders accepting a T-size insert seat. ISO designation N123T3-0080-0000-GS 1125 identifies the exact holder and seat compatibility. Verify toolholder seat size and clamping style before installation.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Power down the machine and engage all lockout-tagout procedures before handling inserts or toolholders. Seat the insert fully in the pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using the correct Torx or hex key. Inspect the insert seat and clamping surfaces for chips or debris before seating a new insert to avoid premature edge failure.
