Sandvik Coromant 5740381 Square-shoulder Face Mill 5 in

Product Description

The SANDVIK COROMANT 5740381 is an indexable square-shoulder face mill designed for high-precision shoulder milling operations in metal cutting applications. Built to the CoroMill Century series specification, this cutter accepts 8 R590-1105.. inserts and operates with a 90-degree lead angle and positive rake geometry. The arbor hole diameter measures 1.5 inches, the maximum cutting diameter is 5 inches, and the overall height is 2.48 inches. Through-coolant capability supports extended tool life and chip evacuation during demanding cuts. The cutter body is constructed from steel and is intended for use by machinists and tooling specialists in production and job-shop environments.

This face mill is suited for square-shoulder milling operations where a true 90-degree wall is required. The close pitch configuration with 8 flutes supports higher feed rates in stable, rigid setups. With a maximum depth of cut of 11 mm (0.433 inches) and right-hand cutting direction, it is appropriate for a wide range of ferrous and non-ferrous workpiece materials when paired with the correct insert grade. Installation and setup are typically performed by CNC machining professionals or toolroom technicians.
