Sgs 31135 Ball End Mill 0.0938 in 3 Flute Solid Carbide

Product Description

The SGS 31135 is a solid carbide ball end mill designed for precision milling in demanding metalworking applications. With a 0.0938-inch (3/32-inch) mill diameter and a 0.2813-inch length of cut, this tool delivers accurate ball-nose profiling and contouring at tight tolerances. The AlTiN coating provides thermal resistance and hardness for extended tool life in high-temperature cutting environments. Three right-hand spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. This is a single-end tool from the SGS Series 5B line, ground from micrograin solid carbide for consistent edge integrity. Machinists and tool-and-die professionals working with CNC machining centers and manual mills are the primary users.

The SGS 31135 is suited for milling ferrous and non-ferrous metals, high-temp alloys, and cast materials, consistent with its primary workpiece material codes covering hardened steels, cast iron, stainless steel, non-ferrous alloys, steel, and superalloys. The 0.0938-inch diameter and 1.5-inch overall length make it well-matched for fine detail work, core and cavity milling, and finishing passes on small contoured features. It is a single-end, non-coolant-through design without extended reach, chipbreaker, variable helix, or variable index geometry, keeping the tool profile straightforward for standard milling setups.

Key Features

• 0.0938-inch (3/32-inch) ball end mill diameter with mill diameter tolerance of +0.000 to -0.002 inches
• AlTiN coating for high thermal resistance and extended tool life in hard and abrasive materials
• 3-flute, right-hand spiral flute design with 30-degree helix angle for efficient chip evacuation
• Micrograin solid carbide construction for edge sharpness and wear resistance
• 1/8-inch shank diameter with tight tolerance of +0.00000 to -0.00032 inches for secure collet fitment
• Series 5B single-end design, regular length, non-coolant-through

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 1/8-inch straight shank. Suitable for workpiece materials corresponding to material codes H, K, M, N, P, and S, which include hardened steels, cast iron, stainless steel, non-ferrous alloys, general steels, and superalloys.

Installation Notes

Installation is performed by qualified machinists using an appropriate collet or end mill holder rated for the 1/8-inch shank diameter. Ensure the machine spindle is fully stopped and power is off before changing tooling. Confirm runout on the shank is within acceptable limits before beginning a cut, as small-diameter carbide end mills are sensitive to excessive runout. Follow the tool manufacturer's recommended speeds and feeds for the specific workpiece material and coating type.
