Osg 4501600 Corner Chamfer End Mill 0.75 in 4 Flute Cobalt

Product Description

The OSG 4501600 is a cobalt corner chamfer end mill designed for precision milling of chamfered edges and angled profiles on ferrous and non-ferrous workpieces. With a 0.75-inch cutting diameter and a 4-inch length of cut, this tool handles both shallow and deep chamfering operations in a single pass. The 4-flute geometry and 30-degree right-hand helix promote efficient chip evacuation and smooth surface finishes. A bright, uncoated finish makes this tool a cost-effective choice for general-purpose and job-shop applications. Machinists and tool-and-die professionals use this type of end mill where tight edge-break tolerances are required.

This end mill is suited for use in CNC machining centers and manual milling machines operating on steel, cast iron, aluminum, and similar materials. The centercutting capability allows direct plunge entry into the workpiece without pre-drilling. The 0.75-inch shank diameter provides a secure, rigid fit in standard ER or side-lock toolholders. Typical applications include deburring bores, chamfering mating faces, and breaking sharp edges on structural or precision components in both light manufacturing and high-mix low-volume shops.

Key Features

• Cobalt construction for improved heat and wear resistance compared to standard high-speed steel
• 4-flute, right-hand cut and right-hand flute geometry for efficient chip flow
• 30-degree helix angle promotes smooth cutting action and reduced chatter
• Centercutting design allows direct plunge entry without a pilot hole
• Bright, uncoated finish suitable for general-purpose and re-sharpenable applications
• Fine pitch classification for precision edge work and controlled material removal

Compatibility

Designed as a standard-shank corner chamfer end mill compatible with 0.75-inch collet chucks, ER toolholders, and side-lock holders used in CNC and manual milling setups.

Installation Notes

Installation and operation of this end mill should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Verify that the toolholder bore and drawbar torque meet the machine manufacturer's specifications before running. Inspect the cutting edges for chips or wear before each use, and do not exceed the recommended depth of cut for the material being machined.
