Osg 484-312708 Square End Mill 5/16 in 4 Flute Carbide Ticn

Product Description

The OSG 484-312708 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. It features a 5/16 inch cutting diameter, a 1-1/2 inch length of cut, and a 6 inch overall length, placing it in the extra long category for extended reach applications. The 4-flute spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and surface finish quality. A TiCN (Titanium Carbonitride) coating increases surface hardness and wear resistance, extending tool life in ferrous and non-ferrous materials. This end mill is centercutting, allowing plunge entry, and is built from micrograin carbide substrate for dimensional stability under load. Installed and run by machinists and CNC operators in production and job shop settings.

This end mill suits applications requiring extended reach into deep pockets, slots, and stepped features where a standard-length tool cannot reach the workpiece. The extra long 6 inch OAL with a 5/16 inch shank makes it compatible with standard ER and straight-shank toolholders of the same bore size. Right-hand cut and right-hand flute orientation conform to conventional milling setups. The Series 484 designation identifies this as part of a coordinated OSG tooling line. Typical applications include slot milling, profile milling, and pocket clearing in steels, stainless, aluminum, and similar machinable alloys.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• TiCN coating increases hardness and reduces built-up edge in ferrous materials
• 4-flute spiral design with 30-degree helix for efficient chip flow and surface finish
• Centercutting geometry allows direct plunge entry without pre-drilling
• Extra long 6 inch OAL enables reach into deep cavities and extended-depth features
• Right-hand cut, right-hand flute — compatible with standard CNC and manual milling spindles

Compatibility

Designed for use with standard 5/16 inch straight-shank or ER-style toolholders. Part of the OSG Series 484 extra long square end mill line. No specific machine model compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator familiar with toolholder runout tolerances and proper torque procedures for set-screw or collet-style holders. Ensure the machine spindle is fully powered down and locked before inserting or removing the tool. Verify shank engagement depth meets the toolholder manufacturer minimum before running. Do not exceed the tool manufacturer recommended depth-of-cut or feed rate for the workpiece material and tool diameter.
