Sandvik Coromant 5735726 Grooving Insert MB09 Solid Carbide

Product Description

The SANDVIK COROMANT 5735726 is a solid carbide grooving insert engineered for precision external grooving operations on CNC lathes and turning centers. Part of the CoroCut MB series, this insert carries a PVD-applied TiAlN/TiN coating that improves wear resistance and extends tool life in steel, stainless, and cast iron applications. It delivers a 2.5 mm (0.0984 inch) cutting width with a maximum depth of cut of 5.5 mm (0.2165 inch) and a 0.20 mm (0.0079 inch) corner radius. The left-hand orientation suits specific toolholder configurations. Machinists and CNC operators working in production or job-shop environments install this insert as a direct replacement in compatible MB-series toolholders.

This insert is suited for grooving tasks on small-diameter workpieces where tight access and precision profile control are required. The CoroCut MB series targets small-part turning and Swiss-type machining applications. With a neutral rake and a 2-degree rake angle, the geometry is designed for controlled chip formation across a range of materials. The ISO code for this insert is MB-09G250-02-16L 1025, and the manufacturer catalog number matches that designation. It is applicable in both production environments and repair shops requiring a reliable, repeatable grooving solution.

Compatibility

Designed for use with CoroCut MB series toolholders that accept insert seat size 9 and left-hand orientation. The ISO designation MB-09G250-02-16L 1025 should be cross-referenced against the toolholder specification to confirm fit before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine is fully powered down and the spindle is locked before exchanging inserts. Use the correct torque wrench and insert clamping screw specified by the toolholder manufacturer — do not use substitute fasteners. Verify seat cleanliness and seating contact before resuming operation to prevent insert movement during cutting.
