Osg 492-0450 Square End Mill 0.045 in 2 Flute Solid Carbide

Product Description

The OSG 492-0450 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 0.045-inch cutting diameter and a 2-flute spiral design, this end mill suits slotting, profiling, and light finishing work in small-feature machining. The micrograin carbide construction provides hardness and wear resistance needed for cutting ferrous and non-ferrous materials. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. At 1-1/2 inches overall length with a 9/64-inch length of cut, it is built for controlled, repeatable performance in CNC machining centers and manual mills.

This end mill is suited for small-diameter work in die, mold, and precision component machining. The 1/8-inch shank diameter fits standard collet systems common in CNC machining centers. The centercutting capability allows plunge entry directly into the workpiece, adding flexibility for pocket milling operations. It is used in job shops, tool rooms, and production environments where fine feature detail and dimensional accuracy are required. A licensed machinist or CNC operator typically selects and installs this tool.

Key Features

• Solid micrograin carbide construction for hardness and extended tool life
• 2-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry into the workpiece
• Right-hand cut and right-hand flute for standard CNC spindle compatibility
• Uncoated finish suitable for general-purpose and non-ferrous milling applications
• Regular length classification for stable, low-deflection cutting at small diameters

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 1/8-inch collet systems in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom operator. Ensure the spindle is fully stopped and locked out before inserting or removing the end mill from the collet. Verify collet size matches the 0.125-inch shank diameter and that the collet and toolholder are clean and free of debris before tightening. At small diameters, avoid excessive overhang beyond the stated length of cut to minimize deflection and tool breakage risk.
