Sgs 02479 Square End Mill 0.05 in 4 Flute Solid Carbide

Product Description

The SGS 02479 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. Built from micrograin carbide, it carries an AlTiN coating that extends tool life in high-heat cutting environments. The cutter measures 0.05 inches in diameter with a 0.15-inch length of cut and a 1.5-inch overall length. A 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. With four flutes in a right-hand spiral configuration, this end mill suits finish milling, slotting, and profiling operations where tight tolerances and surface finish quality are critical.

This end mill is used in CNC machining centers and manual mills where small-diameter, close-tolerance work is required. Typical applications include die and mold work, precision component machining, and micro-feature milling. The 0.125-inch straight-cylindrical shank fits standard collets and ER-style toolholders common in machine shops. Its regular length classification and compact 0.05-inch diameter make it well suited for detailed cavity work and fine feature generation on hardened or high-strength workpieces.

Key Features

• AlTiN coating increases heat resistance and extends tool life in ferrous materials
• Micrograin solid carbide construction provides rigidity and edge retention at small diameters
• Four right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows plunge entry without a pre-drilled hole
• Straight-cylindrical 0.125-inch shank fits standard collet toolholding systems
• Mill diameter tolerance of +0.000 to -0.001 inches for consistent, repeatable cuts

Compatibility

Designed as an OEM-style replacement or direct-application end mill for CNC machining centers and manual mills accepting a 0.125-inch straight-cylindrical shank with ER-style or precision collet toolholding.

Installation Notes

Installation should be performed by a qualified machinist familiar with small-diameter carbide tooling. Ensure the spindle and toolholder are clean and free of debris before seating the shank, as runout at this diameter significantly affects tool life and part accuracy. Secure the shank to the full recommended collet engagement depth. Handle micrograin carbide end mills carefully to avoid chipping the cutting edges during setup.
