Sgs 32438 Tapered Ball End Mill 3 Flute Solid Carbide

Product Description

The SGS 32438 is a solid carbide tapered ball end mill designed for precision milling of contoured surfaces, cavities, and complex 3D geometry. It features a 5-degree taper angle per side and a 0.25-inch small end diameter with a 1/8-inch nose radius, making it well-suited for finishing passes in tight-radius pockets and sloped wall features. The three-flute spiral design with a 28-degree helix angle promotes efficient chip evacuation while maintaining surface finish quality. The uncoated micrograin carbide construction provides edge sharpness and rigidity for demanding cutting conditions. This tool is installed and operated by machinists and CNC programmers working in job shop, aerospace, die and mold, and general precision machining environments.

The SGS 32438 is used in CNC machining centers for milling contoured profiles, tapered walls, and 3D surface finishing operations. Its 1.25-inch length of cut and 4-inch overall length allow reach into moderate-depth cavities while maintaining rigidity. The 0.5-inch shank diameter provides solid tool holding engagement in standard end mill holders and collet chucks. This tool is centercutting, enabling direct plunge entry into workpiece material. Compatible workpiece material codes include H, K, M, N, P, and S, covering a broad range of non-ferrous metals, steels, stainless, cast iron, and high-temperature alloys.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with CNC tooling setup. Secure the 0.5-inch shank in a properly sized end mill holder or precision collet chuck, ensuring adequate engagement length and runout within tool manufacturer tolerances. Confirm spindle speed, feed rate, and depth of cut are calculated for the specific workpiece material and machine capability before cutting. Always inspect the cutting edges for chipping or wear before use.
