Sandvik Coromant 6285759 Grooving Insert Corocut 1-2

Product Description

The SANDVIK COROMANT 6285759 is a solid carbide grooving insert engineered for precision external grooving and parting operations. It carries a TiAlN and AlCr2O3 coating applied via PVD process, delivering strong wear resistance and thermal stability at the cutting edge. The insert features a 2 mm (0.0787 inch) cutting width, a maximum depth of cut of 6 mm (0.2360 inch), and a 1 mm (0.0394 inch) corner radius. It operates with a positive rake geometry and is designed for right-hand cutting setups. This insert belongs to the CoroCut 1-2 series and is installed by machinists and CNC turning specialists on turning centers and lathes.

The 6285759 is suited for grooving and parting applications across a range of workpiece materials where controlled chip formation and dimensional accuracy are required. It fits insert seat size L holders and is compatible with the CoroCut 1-2 tooling system. The RO chip breaker geometry supports consistent chip evacuation during light to medium-depth grooving passes. This insert is appropriate for both production and job-shop environments operating turning centers at standard cutting parameters for carbide tooling.

Key Features

• Solid carbide substrate with PVD-applied TiAlN and AlCr2O3 coating for extended tool life
• 2 mm cutting width (0.0787 inch) for precise, repeatable groove dimensions
• Maximum depth of cut of 6 mm (0.2360 inch) within a usable range of 5 mm to 10 mm (0.2000 to 0.3000 inch)
• 1 mm (0.0394 inch) corner radius reduces stress concentration at groove shoulders
• Positive rake angle promotes free-cutting action and reduces cutting forces
• RO chip breaker designed for reliable chip control in grooving operations
• Multi-use insert designation supports use across compatible CoroCut 1-2 holders

Compatibility

Designed for use with SANDVIK COROMANT CoroCut 1-2 series toolholders accepting insert seat size L. ISO code reference: RG123L1-0200-RO 1115. Catalog number RG123L1-0200-RO 1115 may be used for cross-reference with compatible holder specifications.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine spindle stopped and all stored energy locked out per applicable OSHA lockout/tagout procedures. Seat the insert fully into the holder pocket and confirm the clamping mechanism engages the insert correctly before applying any cutting load. Inspect the insert seat for chips or debris prior to installation, as contamination can affect seating accuracy and edge geometry. Do not exceed the maximum depth of cut specification for the insert size selected.
