Osg 482-2500 Square End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The OSG 482-2500 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 0.25-inch mill diameter, 1.5-inch length of cut, and 4-inch overall length, this tool suits jobs requiring extended reach without sacrificing rigidity. The micrograin carbide substrate provides wear resistance and edge retention in demanding cutting conditions. It features two flutes in a 30-degree right-hand spiral configuration and is centercutting, allowing plunge and ramp entry as well as full peripheral milling. Licensed machinists and CNC operators are the primary installers and users of this tool.

This end mill is suited for general-purpose milling of ferrous and non-ferrous materials where an uncoated solid carbide tool is appropriate. The extra-long length type makes it practical for reaching into pockets, slots, or profiles where standard-length tools cannot reach. It is sold as a single unit and is part of the OSG Series 482 lineup, which targets precision machining in job shop and production environments.

Key Features

• Solid carbide micrograin substrate for extended tool life and edge sharpness
• Two-flute, 30-degree right-hand spiral for efficient chip evacuation
• Centercutting design allows plunge milling and ramp entry
• Extra-long 4-inch overall length for deep-reach applications
• Uncoated finish suitable for non-ferrous and general-purpose materials
• Right-hand cut and right-hand flute orientation for standard CNC and manual mill setups

Compatibility

Designed as a standard 1/4-inch shank square end mill compatible with collet chucks, end mill holders, and tool holders accepting a 0.25-inch straight shank, as used on vertical machining centers, CNC mills, and manual knee mills.

Installation Notes

Installation is performed by machinists using a properly sized collet or end mill holder matched to the 0.25-inch shank diameter. Ensure the spindle and machine are powered off and fully stopped before changing tooling. Confirm runout with a dial indicator after seating the tool, as excess runout accelerates wear and degrades surface finish. Follow the machine tool and cutting tool manufacturer guidelines for speeds, feeds, and depth of cut appropriate to the workpiece material.
