Sgs 30444 Square End Mill 7/32 in 2 Flute Solid Carbide

Product Description

The SGS 30444 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. It features a 7/32 inch (0.2188 inch) cutting diameter, a 5/8 inch length of cut, and a 1/4 inch straight cylindrical shank. The cutting geometry is a two-flute, right-hand spiral with a 30-degree helix angle and an AlTiN coating for heat resistance and extended tool life. Centercutting capability allows plunge entry into the workpiece. This end mill is intended for use by machinists and tooling professionals in CNC and manual milling operations.

The SGS 30444 is suited for milling a broad range of workpiece materials including hardened steels, cast irons, stainless steels, non-ferrous metals, aluminum alloys, and high-temperature alloys, corresponding to material codes H, K, M, N, P, and S. Its regular-length classification and 2-1/2 inch overall length make it appropriate for standard-depth slotting, profiling, and peripheral milling operations in both production and job-shop environments. It is a single-end tool sold individually.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance in ferrous and non-ferrous materials
• AlTiN finish provides thermal protection during high-speed dry or semi-dry cutting
• Two-flute spiral geometry with 30-degree helix angle promotes chip evacuation in slotting cuts
• Centercutting design allows direct plunge milling without pilot drilling
• Right-hand cut and right-hand flute orientation for standard CNC spindle compatibility
• Mill diameter tolerance of plus 0.000 inch to minus 0.002 inch for consistent dimensional accuracy

Compatibility

The SGS 30444 is compatible with workpiece materials designated under material codes H, K, M, N, P, and S, covering hardened steels, cast irons, stainless steels, non-ferrous metals, aluminum alloys, and high-temperature alloys. It fits any 1/4 inch collet or end mill holder with a straight-bore cylindrical retention. No additional specific model or system compatibility data was provided in the product documentation.

Installation Notes

This end mill is installed and serviced by qualified machinists familiar with CNC or manual milling machines. Before tool changes, the spindle must be fully stopped and the machine placed in an e-stop or lockout state per shop safety protocols. Use a properly sized 1/4 inch ER collet or precision end mill holder and torque the retention nut to the collet manufacturer's specification. Inspect the shank and collet bore for chips or burrs before seating the tool to avoid runout that can cause premature tool failure.
