Sgs 30443 Square End Mill 13/64 in 2 Flute Solid Carbide

Product Description

The SGS 30443 is a single-end square end mill designed for precision milling in demanding metalworking applications. Built from micrograin solid carbide and coated with Ti-NAMITE-A AlTiN finish, it delivers extended tool life under high heat and abrasive cutting conditions. The mill measures 0.2031 inches (13/64 inch) in cutting diameter with a 5/8-inch length of cut and a 1/4-inch straight shank. Overall length is 2.5 inches. The 2-flute, spiral-flute geometry with a 30-degree helix angle promotes chip evacuation and surface finish quality. Centercutting capability allows plunge entry. This tool is installed and operated by machinists and tool-and-die professionals in shop environments.

The SGS 30443 is suited for milling steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous materials, and hardened materials. Its AlTiN coating makes it especially effective in dry or minimal-lubrication cutting of ferrous and hard alloys where heat resistance is critical. The regular-length profile and straight shank fit standard collet chucks and end mill holders commonly found on vertical machining centers, CNC mills, and manual knee mills.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• Ti-NAMITE-A AlTiN coating rated for steel, stainless steel, cast iron, high-temp alloys, aluminum, and hardened materials
• Centercutting design enables direct plunge milling
• 2-flute spiral geometry with 30-degree helix angle for efficient chip evacuation
• Right-hand cut, right-hand flute configuration for standard spindle rotation
• Mill diameter tolerance of +0.0000 / -0.0020 inches for consistent fit and finish

Compatibility

Designed for use in standard collet chucks and end mill holders accepting a 1/4-inch straight shank. Compatible with vertical machining centers, CNC milling machines, and manual mills running right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the holder. Verify collet or chuck runout is within acceptable limits before operation, as excessive runout will accelerate tool wear and reduce dimensional accuracy. Follow the machine tool manufacturer guidelines and applicable shop standards for speeds, feeds, and depth of cut based on workpiece material.
