Osg 455-5003 Square End Mill 0.5 in 5 Flute Solid Carbide

Product Description

The OSG 455-5003 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built to Series 455C standards, it features a 0.5 inch cutting diameter, a 2 inch length of cut, and a 4.5 inch overall length with a 0.5 inch shank diameter. The five-flute geometry combined with a 45-degree helix angle supports efficient chip evacuation and smooth surface finishes at higher feed rates. Manufactured from micrograin carbide, this tool delivers the edge retention and rigidity needed for demanding ferrous and non-ferrous materials. It is centercutting-capable, allowing plunge entry directly into the workpiece.

This end mill is suited for general-purpose milling, slotting, profiling, and peripheral milling on CNC machining centers and manual mills. The right-hand cut and right-hand spiral flute configuration is standard for conventional and climb milling setups. The uncoated micrograin carbide construction makes it appropriate for use with cutting fluids on a wide range of materials. Machinists, tool-and-die makers, and precision machine shops performing production or prototype work are the primary users of this tool.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• Five flutes with 45-degree helix angle for efficient chip flow and reduced vibration
• Centercutting design allows direct plunge milling without a pre-drilled hole
• Right-hand cut and right-hand flute orientation for standard CNC and manual mill setups
• Uncoated finish compatible with cutting fluid applications across a broad material range
• Spiral flute geometry supports consistent surface finish on profiling and slotting passes

Compatibility

Designed as an OEM-style solid carbide end mill compatible with standard 0.5 inch collets, end mill holders, and shrink-fit toolholders used on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Secure the shank fully within a properly sized collet or end mill holder to the minimum engagement depth recommended by the toolholder manufacturer before tightening. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut.
