Osg 482-3937 Square End Mill 0.3937 in 2 Flute Carbide

Product Description

The OSG 482-3937 is a solid carbide square end mill designed for precision material removal in milling applications. Built from micrograin carbide, this end mill delivers consistent edge retention and dimensional accuracy across a range of metalworking operations. It features a 0.3937-inch cutting diameter, a 1.7717-inch length of cut, and a 30-degree helix angle that promotes smooth chip evacuation. The 2-flute geometry and right-hand spiral flute configuration make this tool well-suited for slotting, profiling, and plunge cutting where centercutting capability is required. Machinists and tool-and-die professionals rely on this series for demanding material removal tasks.

The 482-3937 is an extra-long length end mill with a 0.3937-inch shank diameter and an overall length of approximately 4.016 inches. Its uncoated micrograin carbide construction is appropriate for use in aluminum, non-ferrous metals, and certain ferrous materials where coating is not required or preferred. The centercutting design allows direct plunge entry into the workpiece. This tool is typically used in CNC machining centers and manual knee mills in job shop, production, and toolroom environments.

Key Features

• Solid micrograin carbide construction for extended edge life and dimensional stability
• 0.3937-inch cutting diameter with 1.7717-inch length of cut for deep-reach operations
• 30-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting geometry enables direct plunge milling without pilot drilling
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Uncoated finish suitable for applications where substrate hardness alone meets performance requirements

Compatibility

Designed as an OSG Series 482 square end mill compatible with standard ER and straight-shank toolholders accepting a 0.3937-inch shank diameter on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before loading or changing tooling. Secure the shank fully within the toolholder to the recommended minimum engagement depth for the holder type in use. Verify runout with an indicator after installation before initiating a cut, as excessive runout accelerates tool wear and reduces surface finish quality.
