Osg 424-0469 Square End Mill 0.0469 in 4 Flute Carbide

Product Description

The OSG 424-0469 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. With a 0.0469-inch (3/64 inch) cutting diameter and four spiral flutes at a 30-degree helix angle, this tool delivers efficient chip evacuation and smooth cutting action in tight-tolerance applications. The micrograin carbide construction provides the hardness and wear resistance required for small-diameter work where tool deflection and breakage are constant concerns. A bright, uncoated finish suits applications where coating interactions with workpiece materials are a consideration. This end mill is installed by machinists and tool-and-die professionals operating CNC machining centers and manual mills.

The 424-0469 fits stub-length applications where minimal tool overhang is required and rigidity is critical. The 0.125-inch shank diameter and 1.5-inch overall length make it well suited for high-speed finishing and light profiling passes in small-feature molds, dies, and precision components. Right-hand cut and right-hand flute orientation are standard for conventional and climb milling on typical machining center spindles. This tool is not centercutting and is not intended for plunge operations.

Key Features

• 0.0469-inch (3/64 inch) cutting diameter for small-feature milling
• Micrograin solid carbide construction for hardness and edge retention
• Four spiral flutes with 30-degree helix angle for efficient chip removal
• Bright, uncoated finish suitable for a wide range of workpiece materials
• Stub-length configuration minimizes overhang and maximizes rigidity
• Right-hand cut, right-hand flute — compatible with standard spindle rotation

Compatibility

Designed as a standard shank end mill for use in CNC machining centers and manual milling machines with ER or collet-style toolholders accepting a 0.125-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with small-diameter carbide tooling. Secure the 0.125-inch shank fully within the collet or toolholder to the manufacturer-specified engagement depth before tightening. Carbide tooling is brittle at small diameters — avoid side-loading or impact during tool changes. This end mill is not centercutting; do not use for direct plunge entry without a pre-drilled pilot hole or ramping strategy.
