Sandvik Coromant 5735856 Grooving Insert MB..09R Solid Carbide

Product Description

The SANDVIK COROMANT 5735856 is a solid carbide grooving insert in the CoroCut MB series, designed for precision grooving operations on CNC lathes and turning centers. This right-hand insert carries a PVD-applied TiAlN/TiN coating that improves wear resistance and edge life across a wide range of workpiece materials. The cutting width measures 8 mm (0.315 inches) with a maximum depth of cut of 4.01 mm (0.158 inches) and a corner radius of 0.40 mm (0.016 inches). The positive rake geometry and R chip breaker promote clean chip evacuation and reduced cutting forces. Machinists and tooling specialists working with small-diameter grooving applications will find this insert a direct fit for MB-style toolholders.

This insert is suited for small-bore and face grooving applications where tight clearances demand a compact insert geometry. The CoroCut MB series is engineered for internal grooving, face grooving, and parting on both CNC turning centers and Swiss-style machines. The insert size designation is 09 with an insert seat size of 09, and it carries ISO code MB-09R080-04-14R 1025. It is a multi-use insert appropriate for production environments where consistent groove dimensions and surface finish are required. Installation is performed by qualified machinists or tooling setters as part of routine insert indexing and replacement workflows.

Key Features

• Solid carbide substrate with PVD TiAlN/TiN coating for extended tool life
• 8 mm cutting width with maximum depth of cut range of 4.00 to 5.00 mm (0.150 to 0.200 inches)
• 0.40 mm corner radius supports precise groove geometry
• Positive rake angle with R chip breaker for efficient chip control
• Right-hand cut orientation for standard CoroCut MB toolholder compatibility
• Multi-use designation suitable for internal grooving, face grooving, and parting

Compatibility

Designed for use with CoroCut MB series toolholders accepting size 09 insert seats. ISO code MB-09R080-04-14R 1025 identifies the toolholder interface and insert geometry. Verify toolholder seat size and hand orientation before installation.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or tooling setter with the machine powered down and the spindle locked. Use the appropriate torx or clamp screw driver as specified by the toolholder manufacturer to seat the insert securely without overtightening. Inspect the insert pocket and clamping surfaces for chips or debris before seating the new insert. Follow the machine tool builder and toolholder manufacturer guidelines for clamping torque and insert orientation verification.
