Osg 496-1873 Square End Mill 4 Flute Solid Carbide

Product Description

The OSG 496-1873 is a solid carbide square end mill designed for precision material removal in milling applications. Built with four flutes and a right-hand cutting direction, it delivers clean, accurate cuts in ferrous and non-ferrous materials. The micrograin carbide construction provides hardness and wear resistance suited to demanding machining environments. A bright, uncoated finish keeps the tool ready for use out of the box or compatible with post-application coatings. The 3/16-inch shank diameter fits standard collets and tool holders in vertical and horizontal milling setups. This is a centercutting tool, allowing direct plunge entry into workpieces without a pre-drilled pilot hole.

This end mill is used in CNC machining centers, manual knee mills, and toolroom applications where tight tolerances and sharp corner definition are required. The single-end configuration is standard for general-purpose roughing and finishing passes. Right-hand flute direction is compatible with conventional right-hand spindle rotation found on most machining equipment. Typical users include machinists, tool and die makers, and maintenance technicians performing precision milling on metal components.

Key Features

• 4-flute design for improved surface finish and chip evacuation
• Micrograin solid carbide construction for hardness and edge retention
• Centercutting geometry allows direct plunge milling
• Right-hand cut and right-hand helix for use with standard spindle rotation
• Bright/uncoated finish suitable for use as-is or with added coating
• Single-end tool for general-purpose roughing and finishing passes

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for standard collet and end mill tool holders accepting a 3/16-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with tool holding and runout tolerances. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention mechanism per the tool holder manufacturer's specifications. Verify runout with a dial indicator before beginning a cut to avoid premature tool wear or workpiece damage.
