Sandvik Coromant 5740074 Square-shoulder End Mill 2 in

Product Description

The SANDVIK COROMANT 5740074 is an indexable square-shoulder end mill designed for high-precision milling operations in metal-cutting applications. Built on the CoroMill 390 platform, this tool features a 2-inch cutting diameter, a maximum depth of cut of 3.93 inches (99.82 mm), and an overall length of 5.384 inches (136.75 mm). It accepts 14 R390-18 series inserts secured by screw clamping and connects to the spindle via a C6 modular connection shank. Through-coolant capability is standard. The body is constructed from steel and is rated for a maximum spindle speed of 7,800 RPM. This is a two-flute, 90-degree lead-angle design intended for ramping and square-shoulder milling strategies.

This end mill is suited for production and job-shop environments running CNC machining centers where square-shoulder profiles, pockets, and ramping tool paths are required. The C6 modular connection makes it compatible with Coromant Capto and other modular tooling systems that accept C6-size interfaces. It is appropriate for steel, stainless, cast iron, and similar workpiece materials depending on insert grade selection. The tool is typically set up and operated by skilled CNC machinists or tooling engineers in both roughing and semi-finishing applications.

Compatibility

Designed for use with R390-18 series indexable inserts. Connects via a C6 modular connection interface. Compatible with machine spindles and tooling adapters that accept the C6 modular connection size.

Installation Notes

Installation and tool assembly should be performed by a qualified CNC machinist or tooling engineer. Ensure the machine spindle and all modular connection components are clean and free of chips before assembly. Power down and lock out the machine before mounting or changing inserts. Follow the tool manufacturer torque guidance printed on insert screws and consult applicable shop safety procedures when handling indexable inserts.
