Sandvik Coromant 5860446 Grooving Insert Corocut Mb

Product Description

The SANDVIK COROMANT 5860446 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Part of the CoroCut MB series, this insert features a TiAlN/TiN PVD coating applied over a solid carbide substrate for wear resistance and extended tool life in demanding cutting environments. The insert carries a 3 mm cutting width, a maximum depth of cut of 5 mm, and a 0.20 mm corner radius. It is sized as an MB09 insert with a left-hand orientation and a neutral rake angle of 0 degrees. Machinists and tooling technicians install this insert in compatible CoroCut MB toolholders for small-diameter and precision grooving work.

This insert is suited for small-part grooving applications in both production and job-shop environments. The left-hand cutting orientation and 90-degree lead angle make it appropriate for face grooving and external grooving on Swiss-type and small-diameter turning setups. The ISO code for this insert is MB09FB3000214L1025, and the manufacturer grade is 1025. The PVD-coated TiAlN/TiN finish performs well in steel, stainless, and similar workpiece materials where edge integrity and surface finish are critical.

Key Features

Compatibility

Designed for use with SANDVIK COROMANT CoroCut MB series toolholders that accept MB09 inserts in a left-hand configuration. ISO designation MB09FB3000214L1025 identifies the exact holder and geometry pairing required.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician with the machine fully powered down and the spindle locked. Use the correct torque wrench and insert screw specified by the toolholder manufacturer — do not use substitute fasteners. Inspect the insert pocket for chips or debris before seating the insert. Verify cutting direction and toolholder orientation match the left-hand specification before resuming machine operation.
