Osg 462-250008 Square End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The OSG 462-250008 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. Part of OSG's Series 462, it features a 0.25-inch diameter, a 1.125-inch length of cut, and a 3-inch overall length. The TiCN (Titanium Carbonitride) coating improves surface hardness and wear resistance, extending tool life in demanding cutting applications. With a 30-degree helix angle and spiral flute geometry, this end mill promotes efficient chip evacuation and stable cutting performance. It is installed and operated by CNC machinists and tool-and-die professionals.

This end mill is suited for slot milling, profiling, and peripheral milling in ferrous and non-ferrous materials. The centercutting capability allows it to plunge directly into workpiece material. The micrograin carbide substrate supports tight tolerances and consistent performance in high-speed machining setups. Its long-length classification makes it appropriate for applications requiring extended reach into deeper pockets or features where a standard-length tool would not reach.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• TiCN coating for improved hardness and extended tool life
• 30-degree helix angle with spiral flutes for efficient chip evacuation
• Centercutting design allows direct plunge entry into material
• Right-hand cut and right-hand flute configuration
• Mill diameter tolerance of +0.000 / -0.001 inches for precision fitment

Compatibility

Designed as a replacement or standard tooling selection for CNC machining centers and manual milling machines that accept a 0.25-inch shank diameter, suitable for use with ER collets, end mill holders, and similar standard toolholding systems.

Installation Notes

This tool is installed by qualified machinists following shop-standard toolholding procedures. Ensure the machine spindle and toolholder are clean and free of debris before seating the shank. Verify runout at the tool tip after clamping. Follow applicable machine manufacturer guidelines and shop safety protocols when setting speeds and feeds for the workpiece material.
