Sgs 31222 Ball End Mill 0.0938 in 4 Flute Solid Carbide

Product Description

The SGS 31222 is a double-end, 4-flute ball end mill engineered for precision milling in demanding metalworking applications. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers hardness and heat resistance suited for high-speed cutting operations. The 0.0938-inch cutting diameter pairs with a 0.1875-inch length of cut and a 30-degree helix angle, producing efficient chip evacuation and smooth finishes on a wide range of workpiece materials. Machinists and tool-and-die professionals install this end mill in CNC machining centers where tight tolerances and tool life are priorities.

This end mill is appropriate for milling operations on ferrous and non-ferrous metals, heat-resistant alloys, and cast irons, as indicated by its primary workpiece material codes H, K, M, N, P, and S. The stub-length configuration and 1/8-inch shank diameter make it well-suited for short-reach applications requiring rigidity and minimal deflection. The double-end design allows the tool to be flipped and reused, extending effective service life before replacement is needed. Typical use cases include slotting, profiling, and contouring in production or prototype machining environments.

Key Features

• Double-end design extends usable tool life by providing two cutting ends per tool
• AlTiN coating improves heat resistance and wear performance in high-speed cutting
• Micrograin solid carbide substrate supports sharp cutting edges and dimensional stability
• 30-degree right-hand spiral flutes promote efficient chip evacuation
• Tight mill diameter tolerance of +0.000 to -0.002 inches supports precision fitment
• Series 14B stub-length profile maximizes rigidity in short-reach setups

Compatibility

Compatible with workpiece materials corresponding to ISO codes H, K, M, N, P, and S, covering hardened steels, cast irons, stainless steels, non-ferrous metals, steel alloys, and superalloys. Designed for use in CNC machining centers and manual mills accepting a 1/8-inch straight shank.

Installation Notes

Installation is performed by qualified machinists following shop safety procedures. Ensure the machine spindle is fully stopped and the tool-holding collet or chuck is clean and free of debris before seating the shank. Verify runout with a dial indicator after clamping to confirm concentricity within acceptable tolerances. Refer to the machine manufacturer guidelines and applicable cutting data for feed, speed, and depth-of-cut recommendations specific to the workpiece material.
