Osg 84400223 Square End Mill 3/32 in 4 Flute Solid Carbide

Product Description

The OSG 84400223 is a square end mill designed for precision milling operations in metal and composite materials. It features a 3/32 inch (0.0938 inch) cutting diameter, a 15/64 inch (0.2344 inch) length of cut, and a 1/4 inch shank diameter with an overall length of 2.5 inches. Constructed from micrograin solid carbide, this tool delivers consistent hardness and wear resistance across demanding cuts. The DUROREY finish reduces friction and extends tool life in high-speed applications. With four flutes and a 43-degree helix angle, it is built for efficient chip evacuation and smooth surface finishes on ferrous and non-ferrous workpieces.

This end mill is suited for use in CNC machining centers and manual milling machines in job shop, production, and toolroom environments. The centercutting design allows direct plunge entry into workpieces without a pre-drilled hole, making it versatile for slotting, profiling, and pocket milling. Its compact 3/32 inch diameter makes it particularly useful for small-feature work, fine detail cuts, and tight-tolerance applications. Machinists, toolmakers, and CNC operators working in aerospace, medical device, and precision parts manufacturing will find this geometry appropriate for their requirements.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• DUROREY finish reduces friction and extends tool life
• 43-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting capability allows direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute orientation for standard spindle compatibility
• Four-flute design balances chip clearance with surface finish quality

Compatibility

Designed as a standard shank solid carbide square end mill compatible with 1/4 inch collets and end mill holders on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Secure the 1/4 inch shank in a clean, properly sized collet or end mill holder, torquing to the holder manufacturer's specification. Inspect the cutting edges for chips or damage before use and verify runout with a dial indicator when tight tolerances are required.
