Osg 404-1968 Square End Mill 4 Flute Solid Carbide

Product Description

The OSG 404-1968 is a solid carbide square end mill designed for precision metal removal in milling applications. Built from micrograin carbide, it delivers consistent edge sharpness and resistance to wear across demanding cutting conditions. The four-flute, single-end design provides a balance of chip evacuation and surface finish quality. With a bright, uncoated finish, this end mill is suited for use in materials where coating buildup or heat-related adhesion is not a concern. The right-hand cut and right-hand flute direction are standard for conventional CNC and manual milling setups. The tool is centercutting, allowing plunge operations in addition to peripheral and slot milling.

This end mill is used in machine shops, tool rooms, and production environments where tight tolerances are required on steel, aluminum, cast iron, and similar machinable materials. The micrograin carbide construction makes it appropriate for both general-purpose and finish milling passes. It is a single-end tool, meaning it is replaced rather than reversed when the cutting end is worn. Machinists and CNC operators running knee mills, vertical machining centers, and similar equipment are the primary installers and users.

Key Features

• Micrograin solid carbide construction for sharp, durable cutting edges
• 4 flutes for improved surface finish and feed rate capability
• Centercutting design allows plunge milling without a pre-drilled hole
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Bright, uncoated finish suitable for applications where coatings are not required
• Single-end tool with fixed helix geometry and no variable index

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard milling chucks, collets, and tool holders accepting a 0.1969 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC operators. The end mill must be secured in a compatible collet or end mill holder torqued to the tool holder manufacturer specifications before spindle engagement. Inspect the collet bore and tool shank for chips or contamination prior to installation. Always confirm spindle rotation direction matches the right-hand cut orientation of this tool before initiating a cut.
