Sandvik Coromant 5735735 Grooving Insert MB09 1025

Product Description

The SANDVIK COROMANT 5735735 is a solid carbide grooving insert from the CoroCut MB series, designed for precision parting and grooving operations on CNC lathes and turning centers. This left-hand insert features a 2 mm cutting width and a maximum depth of cut of 4 mm, making it well suited for small-part and Swiss-type turning applications. The PVD-applied TiAlN/TiN coating provides thermal resistance and edge wear protection during interrupted cuts and continuous grooving cycles. It carries a neutral rake geometry with a 2-degree rake angle and a 0.20 mm corner radius, supporting controlled chip formation on a range of workpiece materials. Licensed machinists and CNC operators install this insert as a direct replacement in compatible CoroCut MB toolholders.

This insert is intended for use in industrial and production turning environments where small-diameter grooving, face grooving, and parting operations are required. The MB09 insert size and 9 mm insert seat size place it in the smaller-diameter CoroCut MB toolholder class, commonly used in Swiss-type, multi-spindle, and small-part CNC turning cells. The ISO code MB-09G200-02-14L 1025 identifies the exact geometry and grade, and should be referenced when ordering or confirming toolholder compatibility. The 1025 manufacturer grade designation indicates the specific substrate and coating combination optimized for this insert style.

Key Features

• Solid carbide substrate with PVD TiAlN/TiN coating for extended edge life in grooving applications

• Left-hand orientation for specific toolholder and approach-direction requirements
• 0.20 mm corner radius (0.0079 inches) supports sharp-shouldered groove profiles
• Multi-use capable insert with neutral rake and 90-degree lead angle

Compatibility

Designed for use with SANDVIK COROMANT CoroCut MB series toolholders that accept MB09 insert seat size 9. Reference ISO code MB-09G200-02-14L 1025 and manufacturer catalog number MB-09G200-02-14L 1025 when confirming toolholder fitment.

Installation Notes

Insert replacement and seating should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before handling or indexing inserts. Use the appropriate Torx or insert-clamp key specified by the toolholder manufacturer to secure the insert — do not overtighten or substitute fasteners. Verify insert orientation and seating before returning the machine to operation.
