Osg 484-7500 Square End Mill 3/4 in 4 Flute Solid Carbide

Product Description

The OSG 484-7500 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide, it delivers consistent edge integrity and resistance to wear in demanding cutting conditions. The cutter features a 3/4-inch diameter with a 3-inch length of cut, a 30-degree helix angle, and four spiral flutes in a right-hand cut, right-hand flute configuration. At 6 inches overall length, it falls in the extra-long category, making it well suited for deep-pocket and extended-reach operations. Centercutting capability allows plunge entry without a pre-drilled pilot hole. Licensed machinists and CNC operators are the typical end users for this tool.

This end mill is intended for ferrous and non-ferrous metal stock removal and finishing passes on CNC machining centers and manual knee mills. The extra-long overall length supports deep-cavity milling, tall workpiece profiles, and setups requiring clearance between the spindle nose and the workpart. The uncoated micrograin carbide construction suits shops that prefer to apply their own coatings or that run at lower cutting speeds with high-quality coolant. It is equally applicable to job-shop general machining and production environments running repeat part cycles.

Key Features

• Solid micrograin carbide construction for superior edge retention and wear resistance
• 4-flute spiral configuration with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge cuts without a pre-drilled hole
• Right-hand cut and right-hand flute orientation standard for conventional CNC spindle use
• Extra-long 6-inch OAL with 3-inch length of cut for deep-pocket and extended-reach work
• Uncoated finish compatible with coolant-assisted cutting or post-purchase coating processes

Compatibility

Designed as an OEM-style solid carbide square end mill suitable for CNC machining centers and manual milling machines accepting a 3/4-inch straight shank toolholder.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the 3/4-inch shank in a clean, properly sized collet or end mill holder and torque the retention mechanism to the toolholder manufacturer specification. Inspect the collet bore and shank for chips or contamination before clamping. Confirm spindle direction is set to right-hand rotation before engaging the cut, and always bring the spindle to a full stop before measuring, adjusting, or removing the tool.
