Sgs 30442 Square End Mill 3/16 in 2 Flute Solid Carbide

Product Description

The SGS 30442 is a solid carbide square end mill designed for precision milling in a wide range of materials. It features a 3/16 inch cutting diameter with a 5/8 inch length of cut and a 2 inch overall length. The two-flute, spiral geometry with a 30-degree helix angle promotes efficient chip evacuation. An AlTiN coating provides heat resistance and extended tool life in demanding cutting conditions. Built from micrograin carbide, this end mill delivers the rigidity and edge retention required for consistent performance in production environments. It is installed and operated by machinists and toolroom professionals.

This end mill is suited for slot milling, profiling, and contouring operations across a broad range of workpiece materials. The primary workpiece material codes include H, K, M, N, P, and S, covering hardened materials, cast iron, stainless steel, non-ferrous alloys, steel, and high-temperature alloys. Its centercutting design allows plunge entry, making it versatile for both roughing and finishing passes. The straight cylindrical shank fits standard collet chucks and end mill holders common in vertical machining centers and manual mills.

Key Features

• Solid micrograin carbide construction for rigidity and long edge life
• AlTiN coating for thermal resistance in high-speed and dry cutting applications
• Centercutting design permits direct plunge entry into the workpiece
• 30-degree helix angle with spiral flutes for effective chip evacuation
• Right-hand cut and right-hand flute configuration
• Mill diameter tolerance of +0.000 / -0.002 inches for precise fit

Compatibility

Compatible with workpiece material codes H, K, M, N, P, and S as specified by the manufacturer. Fits standard collet chucks and end mill holders accepting a 3/16 inch straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or end mill holder to the recommended engagement depth to prevent pullout. Verify runout with a dial indicator before beginning the cut, as excessive runout accelerates tool wear and reduces surface finish quality.
