With a 0.017-inch cutting diameter and a 0.0255-inch length of cut, this tool handles tight-tolerance work in hardened and difficult-to-machine materials. The 2-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation at small diameters. The Tuffy material grade solid carbide substrate provides the rigidity and wear resistance needed when working at this scale. At 1.5 inches overall length with a 0.125-inch straight cylindrical shank, it fits standard collet setups. Machinists and toolmakers performing detail milling, slotting, and profiling operations at micro scales are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThe SS-2-017 is suited for precision milling in metalworking, mold and die, medical device, and electronics manufacturing environments. Its stub-length design minimizes deflection when machining small features in ferrous and non-ferrous materials. The centercutting geometry allows plunge entry, expanding the range of operations this tool can perform in a single setup. It is designed for use on CNC machining centers and high-speed spindle setups capable of the elevated RPMs required for 0.017-inch diameter tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.017-inch cutting diameter with a 0.0255-inch length of cut for precise micro-milling\u003c\/li\u003e\n\u003cli\u003eSolid carbide Tuffy material grade for enhanced hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003e2-flute, right-hand cut and right-hand spiral flute design with 30-degree helix angle\u003c\/li\u003e\n\u003cli\u003eCentercutting capable  -  supports direct plunge entry\u003c\/li\u003e\n\u003cli\u003eStub-length body minimizes deflection at small diameters\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 0.125 inches fits standard ER collets\u003c\/li\u003e\n\u003cli\u003eUncoated finish for compatibility with a range of materials and cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/8-inch collet systems on CNC machining centers and high-speed spindle platforms requiring micro-diameter square end mills in the ROBBJACK SS-2 series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, powered-down state. Seat the straight cylindrical shank fully and evenly in the collet before tightening to ensure concentricity and minimize runout. At this diameter, even minor runout or collet contamination can cause tool breakage. Verify spindle speed and feed rate parameters against published cutting data for 0.017-inch carbide tooling before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.017 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0005 \/ -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.0255 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.040 \/ -0.040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Tuffy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SS-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 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: ROBBJACK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SS-2-017\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":51972004970802,"sku":"SS-2-017","price":45.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/659b70b92e6d3e7b709d7c97795ee06a_b4425c10-c2df-401f-ac8a-b4d9ba5fb980.jpg?v=1789960630","url":"https:\/\/voomisupply.com\/products\/robbjack-ss-2-017-square-end-mill-0-017-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
