Sgs 30440 Square End Mill 5/32 in 2 Flute Solid Carbide

Product Description

The SGS 30440 is a solid carbide square end mill designed for precision material removal in metalworking and machining applications. It features a 5/32 inch (0.1563 inch) mill diameter, a 1/2 inch length of cut, and a 2-inch overall length with a 3/16 inch straight-cylindrical shank. The two-flute, right-hand spiral design runs at a 30-degree helix angle, and the AlTiN coating improves heat and wear resistance at elevated cutting temperatures. Micrograin carbide construction supports tighter tolerances and longer tool life compared to standard carbide grades. This is a single-end, centercutting tool suited for slotting, profiling, and plunge operations.

The SGS 30440 is used in CNC machining centers and manual milling machines across job shop, production, and tool-and-die environments. Its primary workpiece material codes include H, K, M, N, P, and S, indicating suitability for hardened steels, cast irons, stainless steels, non-ferrous metals, steel alloys, and heat-resistant superalloys. The regular length classification and straight shank make it a standard choice for general-purpose milling where extended reach is not required. Machinists and CNC operators working with diverse material types will find this a versatile single-end option.

Key Features

• Solid micrograin carbide construction for tight tolerances and extended tool life
• AlTiN coating provides oxidation resistance and thermal protection at high cutting speeds
• 2-flute design with right-hand cut and right-hand spiral at 30-degree helix angle
• Centercutting geometry allows direct plunge entry into workpiece
• Mill diameter tolerance of +0.000 / -0.002 inches for precise fit
• Shank diameter tolerance of -0.0001 / -0.0004 inches for consistent spindle engagement

Compatibility

Compatible with workpiece material codes H, K, M, N, P, and S as specified by the manufacturer, covering hardened steels, cast irons, stainless steels, non-ferrous metals, general steels, and superalloys. Fits standard 3/16 inch collets or tool holders with straight-cylindrical shank acceptance.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify collet size matches the 3/16 inch shank diameter and that runout is within acceptable limits before beginning a cut. Follow shop safety procedures and applicable OSHA machine guarding requirements when operating milling equipment.
