Sandvik Coromant 5735821 Cutoff Insert 2.5mm Corocut 1-2

Product Description

The SANDVIK COROMANT 5735821 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries manufacturer grade 1105 with a TiAlN coating applied via PVD process, providing wear resistance at elevated cutting speeds. The insert features a 2.50 mm cutting width, a neutral lead angle, and a CM chipbreaker geometry engineered to control chip formation during cutoff passes. Machinists and CNC operators in production and job-shop environments install this insert in CoroCut 1-2 series toolholders for parting steel, stainless, and similar materials.

This insert is suited for external grooving and cutoff applications on small to medium diameter workpieces in both production and maintenance machining environments. The CoroCut 1-2 series is widely used in high-volume turning cells where consistent chip control and predictable insert life are priorities. The CM chipbreaker geometry works across a range of feed rates and depths, making it applicable in general-purpose parting operations. Qualified machinists and CNC programmers familiar with insert tooling and turning center setup are the typical installers.

Key Features

• Solid carbide substrate with grade 1105 for thermal and wear resistance
• TiAlN coating via PVD process for extended tool life at high cutting speeds
• 2.50 mm cutting width with 0 degree neutral lead angle
• CM chipbreaker geometry for controlled chip evacuation during parting
• 7.00 degree relief angle reduces rubbing and side cutting forces
• 0.20 mm corner radius for defined edge geometry at the parting groove
• Maximum depth of cut of 18.90 mm supports a range of workpiece diameters

Compatibility

Designed for use in SANDVIK COROMANT CoroCut 1-2 series toolholders requiring an F seat size insert. Catalog number N123F2-0250-0002-CM 1105 identifies the exact toolholder pocket and clamping system compatibility.

Installation Notes

This insert is installed and replaced by qualified machinists or CNC tooling technicians. Power down and lock out the machine before changing inserts. Use the appropriate torque wrench and clamp screw specified for the CoroCut 1-2 toolholder to avoid insert seat damage. Verify insert seating and clamp engagement before resuming cutting operations.
