Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers hardness and heat resistance suitable for high-speed cutting. The cutter measures 0.0625 inches in diameter with a 0.125-inch length of cut, a 0.125-inch shank diameter, and a 1.5-inch overall length. The 4-flute, 30-degree right-hand helix geometry promotes efficient chip evacuation and smooth surface finishes. Licensed machinists and CNC operators install this tool in milling machine spindles for fine-detail work.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling small features, contours, and complex 3D profiles in a wide range of workpiece materials. Its AlTiN coating and micrograin carbide substrate make it effective in harder and more abrasive materials. Primary workpiece material codes supported include H, K, M, N, P, and S, covering categories such as hardened steels, cast irons, stainless steels, non-ferrous metals, carbon steels, and high-temperature alloys. The stub length designation keeps deflection low when working in tight geometries or shallow pockets.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and extends tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003e4-flute, 30-degree right-hand helix for efficient chip evacuation and smooth finishes\u003c\/li\u003e\n\u003cli\u003eStub length type minimizes deflection in fine-detail applications\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 to -0.002 inches ensures consistent sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with workpiece material codes H, K, M, N, P, and S as designated by the SGS Series 14B classification.

Secure the 0.125-inch shank in a properly sized collet or end mill holder to the torque specification of the spindle system in use. Confirm runout with a dial indicator before beginning a cut. Always power down and lock out the spindle before changing tooling. Do not exceed the recommended depth of cut for the 0.125-inch length of cut to avoid tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\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\u003eSingle or Double End\u003c\/strong\u003e: Double\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 14B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 31220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51753750298930,"sku":"31220","price":56.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab9e6295ac59cf22adcd5981d296ee86.jpg?v=1788940292","url":"https:\/\/voomisupply.com\/products\/sgs-31220-ball-end-mill-0-0625-in-4-flute-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
