Sgs 00519 Square End Mill 0.01 in 4 Flute Solid Carbide

Product Description

The SGS 00519 is a solid carbide square end mill designed for precision milling of small features and fine detail work. With a cutting diameter of 0.01 inches and a length of cut of 0.03125 inches (1/32 inch), this tool is built for micro-milling applications where tight tolerances are required. The 4-flute, right-hand spiral design provides efficient chip evacuation and a smooth cutting action. The micrograin carbide construction delivers rigidity and wear resistance in demanding materials. A straight cylindrical shank measuring 0.125 inches in diameter fits standard collet chucks, and the 1.5-inch overall length suits typical CNC and manual milling setups. This tool is installed and operated by machinists and toolroom professionals.

The SGS 00519 is suited for micro-feature milling on CNC machining centers and precision manual mills. Typical applications include engraving, slotting, and profiling of small details in metals, composites, and engineered plastics. The centercutting geometry allows direct plunge entry, giving the operator flexibility in toolpaths without requiring a pre-drilled start hole. The regular length classification and 30-degree helix angle make it appropriate for general-purpose micro-milling where a balance of chip flow and cutting stability is needed.

Key Features

• 0.01 inch cutting diameter with a mill diameter tolerance of +0.0000 / -0.0008 inches for precise feature sizing
• 4-flute spiral design with a 30-degree helix angle for balanced chip flow and surface finish
• Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Micrograin solid carbide construction for rigidity and extended tool life in hard materials
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Straight cylindrical shank (0.125 inches) for compatibility with standard collet systems

Compatibility

Designed for use in standard collet chuck systems accepting a 0.125 inch straight cylindrical shank, compatible with CNC machining centers and manual mills set up for micro-milling operations. Belongs to SGS Series 1810.

Installation Notes

Installation and tool changes must be performed with the machine spindle at a complete stop and locked out per applicable machine guarding procedures. Seat the straight shank fully into the collet and verify runout before beginning a cut, as excessive runout at this diameter will cause immediate tool failure. Feeds, speeds, and depth of cut must be appropriate for the 0.01 inch diameter; consult the manufacturer's cutting data for the specific workpiece material. Micro-diameter end mills are fragile and should be handled carefully to prevent chipping the cutting edges before use.
