Osg 414-046911 Square End Mill 3/64 in 4 Flute Carbide Tialn

Product Description

The OSG 414-046911 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. Built to Series 414 specifications, it features a 3/64 inch (0.0469 inch) cutting diameter and a 4-flute spiral configuration with a 30-degree helix angle. The TiAlN coating provides heat resistance and extended tool life at higher cutting speeds. With a 1/8 inch shank diameter and 1-1/2 inch overall length, this end mill is suited for small-feature profiling, slotting, and contouring in machining centers and CNC mills. Micrograin carbide construction supports consistent edge sharpness throughout the tool life.

This end mill is intended for applications requiring tight tolerances in small-bore or fine-detail work. The 3/32 inch length of cut limits depth-per-pass but delivers rigidity critical when milling hardened steels, stainless alloys, or high-temperature materials. It is well suited for die and mold work, instrument components, and precision parts manufacturing where dimensional accuracy at small scales is required. A licensed machinist or CNC programmer typically selects and runs this tooling in a production or job-shop environment.

Key Features

• Solid micrograin carbide construction for consistent edge retention and tool life
• TiAlN coating for elevated heat resistance at high cutting speeds
• 4-flute spiral design with 30-degree helix angle for smooth chip evacuation
• Centercutting geometry allows direct plunge entry into workpiece
• Right-hand cut and right-hand flute orientation — standard CNC spindle compatibility
• 1/8 inch shank fits standard collets and toolholders without adapters

Compatibility

Designed as an OEM-style solid carbide square end mill for use in CNC machining centers and manual mills equipped with standard 1/8 inch collet or toolholder systems.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. The spindle must be fully stopped and the machine placed in an e-stop or lockout state before changing tooling. Ensure the collet and toolholder are clean and free of chips before seating the shank. Do not exceed the recommended length of cut for the cutting diameter to avoid deflection or tool breakage on this small-diameter end mill.
