Sgs 31186 Square End Mill 5/16 in 4 Flute Solid Carbide Altin

Product Description

The SGS 31186 is a double-end, square-profile solid carbide end mill designed for high-performance milling in a wide range of materials. It features a 5/16-inch cutting diameter, a 1/2-inch length of cut, and a 30-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The micrograin carbide substrate provides the hardness and edge retention needed for demanding applications. An AlTiN coating adds thermal resistance and surface hardness, extending tool life in ferrous and high-temperature alloy cuts. This tool is installed and used by machinists and tool-and-die professionals in CNC and manual milling operations.

The SGS 31186 is suited for milling operations across a broad spectrum of workpiece materials, including cast iron, non-ferrous metals, stainless steel, titanium alloys, carbon steel, and high-temperature alloys, corresponding to material codes H, K, M, N, P, and S. Its stub length classification makes it a preferred choice when rigidity and reduced deflection are priorities, such as in close-tolerance slotting, profiling, and peripheral milling. The double-end design extends usable tool life by providing two cutting ends per tool.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• AlTiN coating for elevated thermal resistance and extended tool life in ferrous and exotic alloy cuts
• 30-degree right-hand helix promotes smooth chip flow and reduced cutting forces
• Double-end design provides two usable cutting ends per tool
• Center-cutting capable — supports plunge and ramp entry cuts
• Stub length classification maximizes rigidity and minimizes deflection
• Right-hand cutting direction for standard CNC and manual milling setups

Compatibility

Designed for use in standard straight-bore milling chucks, collet holders, and shrink-fit toolholders accepting a 5/16-inch straight-cylindrical shank. Suitable for milling workpiece material groups H, K, M, N, P, and S as specified by the manufacturer.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel following shop safety procedures. Ensure the spindle is fully stopped and de-energized before changing tooling. Secure the shank to the minimum recommended engagement depth in the holder and verify runout before beginning a cut. Do not exceed the tool manufacturer's recommended cutting parameters for the workpiece material and coating type.
