Osg 482-7500 Square End Mill 3/4 in 2 Flute Solid Carbide

Product Description

The OSG 482-7500 is a solid carbide square end mill designed for precise milling operations in metalworking and machining environments. Measuring 3/4 inch in diameter with a 3-inch length of cut and a 6-inch overall length, this tool falls into the extra-long category, making it well suited for deep-pocket and extended-reach applications. Built from micrograin solid carbide, it offers excellent hardness and wear resistance compared to high-speed steel alternatives. The 2-flute geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. It is center-cutting capable, allowing direct plunge entry into material without a pilot hole.

This end mill is intended for use in CNC machining centers and manual milling machines where extended reach into deep cavities or workpiece features is required. The right-hand cut and right-hand spiral flute configuration is standard for conventional milling setups. The uncoated micrograin carbide construction performs well in a range of materials when used with appropriate speeds, feeds, and cutting fluid. Machinists, tool-and-die makers, and production shop technicians are the primary users of this tool.

Key Features

• 3/4 inch mill diameter with matching 3/4 inch shank diameter for secure tool holding
• 3-inch length of cut supports deep-pocket and extended-reach milling
• 6-inch overall length classified as extra-long in the Series 482 lineup
• Micrograin solid carbide construction for durability and dimensional stability
• 30-degree helix angle spiral flute for effective chip evacuation
• Center-cutting design allows direct plunge milling without pre-drilling

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 3/4 inch collets, end mill holders, and hydraulic or shrink-fit toolholders used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before loading or unloading the tool. The shank should be fully seated in the toolholder to the minimum insertion depth recommended for the holder type. Verify runout with a dial indicator after tool change to ensure accurate setup before cutting.
