Osg 4500800 Corner Chamfer End Mill 0.625 in 4 Flute Cobalt

Product Description

The OSG 4500800 is a corner chamfer end mill designed for machining chamfered edges and angular profiles on metal workpieces. Built from cobalt high-speed steel, this tool delivers heat and wear resistance in demanding cutting applications. It features a 0.625-inch cutting diameter, a 3-inch length of cut (LOC), and a 4-flute configuration that balances chip evacuation with surface finish quality. The 30-degree helix angle supports smooth cutting action across a range of ferrous and non-ferrous materials. The bright, uncoated finish makes it straightforward to inspect for wear. This end mill is center-cutting, allowing it to plunge directly into the workpiece without a pre-drilled entry hole.

The OSG 4500800 is suited for job shops, tool rooms, and production machining environments where chamfering, beveling, and angular profiling are routine operations. The fine pitch and right-hand cutting and flute direction make it appropriate for standard vertical and horizontal milling machine setups. Its 5/8-inch shank diameter fits common collet and end mill holder systems. It is typically installed and operated by machinists and CNC programmers working in metal fabrication, mold making, and general precision machining.

Key Features

• Corner chamfer geometry for beveling and angular edge profiling
• Cobalt construction for improved heat resistance over standard HSS
• 4-flute, fine-pitch design balances chip removal and finish quality
• 30-degree helix angle for smooth, consistent cutting action
• Center-cutting capability allows direct plunge entry
• Bright, uncoated finish for easy visual wear inspection

Compatibility

Designed for use in standard milling machines and CNC machining centers accepting a 5/8-inch shank via collet chuck or end mill holder. Suitable for cutting ferrous and non-ferrous metals in right-hand spindle configurations.

Installation Notes

This end mill is installed by a machinist or CNC operator using an appropriately sized collet or end mill holder rated for a 5/8-inch shank. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Confirm runout on the holder is within acceptable tolerance before beginning cuts to avoid premature tool wear. Follow the machine manufacturer and applicable shop safety guidelines for speeds and feeds appropriate to the workpiece material.
