Constructed from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), this tool delivers heat resistance and edge retention when cutting ferrous alloys, stainless steels, titanium, and superalloys. The 1\/2-inch diameter cutting geometry pairs with a 1-1\/4-inch length of cut and 3-1\/4-inch overall length, making it well-suited for profiling, contouring, and 3D surface work. Variable helix and variable index geometry reduce chatter and harmonic vibration during high-feed passes. Installed by machinists and toolroom professionals running CNC milling centers.\u003c\/p\u003e\u003cp\u003eThis end mill is built for finishing cuts on materials classified under workpiece codes H, K, M, P, and S  -  covering tool steels, cast iron, non-ferrous metals, general steels, and high-temperature alloys. The right-hand spiral flute design and right-hand cutting direction are standard for conventional CNC milling setups. The regular-length profile fits most standard toolholders without requiring extended-reach adapters. It is a practical choice for shops running tight-tolerance contour programs where surface finish is the primary objective.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating provides high-temperature oxidation resistance for dry and semi-dry cutting\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for superior hardness and edge sharpness retention\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index design suppress chatter and improve surface finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral fluting for compatibility with standard CNC spindles\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with a 1\/2-inch shank diameter for secure toolholder engagement\u003c\/li\u003e\n\u003cli\u003eRated for finishing on steels, stainless, titanium, superalloys, cast iron, and non-ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fit for CNC milling applications requiring a 1\/2-inch shank ball end mill in a regular-length configuration.

Secure the shank in a collet chuck or end mill holder rated for the shank diameter, ensuring proper runout before operation. Verify spindle speed and feed rate against material and coating recommendations before engaging the cut. Do not use this tool in a worn or improperly sized holder, as runout beyond tolerance will accelerate edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.00043 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Z1B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Workpiece Materials\u003c\/strong\u003e: H, K, M, P, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 36591\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":67988315308338,"sku":"36591","price":200.88,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5f513f10a49f75f93aa052126aac10f_e8c8e3ff-8f76-48ac-971c-a51d3730a64c.jpg?v=1792291410","url":"https:\/\/voomisupply.com\/products\/sgs-36591-ball-end-mill-1-2-in-4-flute-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
