Sandvik Coromant 5860443 Grooving Insert MB09 1025

Product Description

The SANDVIK COROMANT 5860443 is a solid carbide grooving insert from the CoroCut MB series, designed for precise grooving and parting operations on CNC lathes and turning centers. Built to ISO code MB-09FB150-02-14L 1025, this insert features a PVD-applied TiAlN/TiN coating that extends tool life in demanding cut conditions. The left-hand configuration suits specific toolholder orientations common in turning applications. With a 1.5 mm cutting width and a maximum depth of cut of 2.5 mm, it is suited for small-diameter internal and external grooving work. Grade 1025 provides a balanced combination of toughness and wear resistance for a range of workpiece materials.

This insert is intended for use in precision turning operations where tight groove tolerances and consistent surface finish are required. It is particularly well-suited for small-bore internal grooving applications on lathes equipped with CoroCut MB compatible toolholders. The neutral rake angle with a 2.00-degree rake and 0.20 mm corner radius make it appropriate for fine-finish grooving passes on ferrous and non-ferrous materials. CNC machinists and toolroom operators working on production or prototype turning jobs will find this insert applicable in both high-volume and short-run setups.

Key Features

• Solid carbide construction with PVD TiAlN/TiN coating for extended wear resistance
• 1.5 mm cutting width for narrow, precise groove profiles
• Maximum depth of cut of 2.5 mm, with a rated range of 2.0 mm to 3.0 mm
• Left-hand insert orientation for compatible toolholder configurations
• 0.20 mm corner radius for controlled edge geometry and finish quality
• Multi-use designation supports use across varied grooving applications

Compatibility

Designed for use with SANDVIK COROMANT CoroCut MB series toolholders accepting size 09 insert seats. ISO code MB-09FB150-02-14L 1025 confirms toolholder fitment requirements. Verify toolholder compatibility using the ISO code before installation.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle is fully stopped and the turret is in a safe indexed position before changing inserts. Use the appropriate torque wrench and insert clamp screw specified by the toolholder manufacturer — do not overtighten or substitute fasteners. Confirm insert seating is flush and secure before initiating a test cut.
