Sandvik Coromant 5762390 Indexable Milling Cassette

Product Description

The SANDVIK COROMANT 5762390 is an indexable milling cassette designed for use with CoroMill 331 slotting mill toolholders. It accepts the N331.1A-08 insert style and is compatible with R/L331.52..Txx toolholder configurations. This cassette serves as a precision seating and clamping component within the cutter body, holding the indexable insert at the correct geometry for repeatable slotting operations. It is installed and replaced by machinists and tooling technicians performing scheduled maintenance or insert changeovers on CoroMill 331 assemblies. The cassette's design supports consistent insert positioning, which directly affects surface finish, dimensional accuracy, and tool life in production milling environments.

This cassette is suited for slotting mill applications in both production shop and job shop environments. It fits within the CoroMill 331 modular system, which is commonly used for full-width slotting, grooving, and side milling operations on machining centers and milling machines. The R/L331.52..Txx toolholder designation covers both right-hand and left-hand cutter body variants in the 331.52 series with Txx clamping, making this cassette applicable across a range of cutter diameters within that family. Technicians typically keep replacement cassettes on hand to minimize downtime during insert changeovers or when cassette wear affects insert seating integrity.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the spindle fully stopped and the machine locked out per applicable lockout/tagout procedures. The cutter body should be secured in a vise or fixture during cassette removal and installation to prevent movement and protect cutting edges. Use only manufacturer-specified torque drivers or keys for cassette clamping screws to avoid deforming the seating pocket. Inspect the cassette pocket and clamping surfaces for chips or debris before seating the replacement cassette.
