Sgs 31401 Square End Mill 1/32 in 4 Flute Solid Carbide

Product Description

The SGS 31401 is a double-end, four-flute square end mill ground from micrograin solid carbide for precision milling in demanding applications. The tool measures 0.0313 inches (1/32 inch) in cutting diameter with a 0.0625-inch (1/16-inch) length of cut, making it well suited for fine detail work and tight-tolerance features. A 30-degree helix angle promotes efficient chip evacuation while maintaining edge integrity. The bright, uncoated finish is typical for micrograin carbide tools used where coating interactions with workpiece materials are a concern. This is a stub-length configuration with a 1.5-inch overall length and a 1/8-inch straight-cylindrical shank. Installation is performed by qualified machinists and tool-and-die professionals in CNC machining centers and manual mills.

This end mill is designed for high-precision milling operations where small-diameter tooling is required. It is centercutting and right-hand cutting with a right-hand spiral flute direction, making it compatible with standard spindle configurations. The SGS 31401 is well matched to work in material categories including cast iron, non-ferrous metals, steel, stainless steel, high-temperature alloys, and superalloys, corresponding to material codes H, K, M, N, P, and S. It is part of SGS Series 11B and is commonly used in aerospace, medical device, and precision mold applications where fine features demand small-diameter tooling.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention in small-diameter tooling
• Double-end design provides two usable cutting ends, extending tool life between changeovers
• 30-degree helix angle promotes chip flow and reduces heat buildup during cutting
• Centercutting capable, allowing direct plunge entry into workpiece material
• Stub-length configuration minimizes deflection when milling fine or detailed features
• Bright/uncoated finish suitable for a wide range of workpiece materials including non-ferrous and ferrous alloys

Compatibility

Designed for use with material categories H (cast iron), K (non-ferrous metals), M (stainless steel), N (non-ferrous light metals), P (steel), and S (high-temperature and superalloys), as stated in the product specifications. Compatible with standard 1/8-inch collet systems in CNC machining centers and manual milling machines with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down or placed in an e-stop state before changing tooling. Secure the 1/8-inch straight shank in a properly sized, clean collet or end mill holder and tighten to the machine manufacturer's specified torque. Inspect the cutting edges under magnification before use, as micro-diameter carbide tools are susceptible to chipping during handling.
