Osg 404-1094 Square End Mill 7/64 in 4 Flute Carbide

Product Description

The OSG 404-1094 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 7/64 inch (0.1094 inch) cutting diameter, a 3/8 inch length of cut, and a 1/8 inch shank diameter with an overall length of 1.5 inches. The 4-flute geometry with a 30-degree helix angle and spiral flute configuration promotes efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide, this end mill is uncoated and suitable for general-purpose milling where the base carbide substrate performs without additional surface treatment. It is centercutting, allowing plunge entry into the workpiece.

This end mill is intended for use in CNC machining centers, manual mills, and high-speed spindles where a small-diameter, short-reach tool is required. Its regular length profile and 1/8 inch shank make it compatible with standard collets and toolholders used in precision work on ferrous and non-ferrous metals, plastics, and composites. The right-hand cut and right-hand flute orientation follow the standard convention for most milling setups. It is suited for slot milling, profiling, and light pocketing operations.

Key Features

• 7/64 inch (0.1094 inch) cutting diameter for small-feature precision milling
• 4-flute, spiral flute design with 30-degree helix angle for efficient chip removal
• Solid micrograin carbide construction for rigidity and wear resistance
• Centercutting capability allows direct plunge entry
• Right-hand cut and right-hand flute, standard orientation for most machining setups
• Uncoated finish suited for general-purpose and dry milling applications

Compatibility

Designed as a standard square end mill for use with 1/8 inch collets and toolholders in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or toolholder to the recommended engagement depth per the toolholder manufacturer. Verify runout after installation before beginning a cut.
