Built from solid carbide in RobbJack's Tuffy material grade, it delivers the rigidity and edge retention needed at extremely small diameters. The cutting diameter measures 0.015 inches with a 0.045-inch length of cut and a 1\/8-inch straight-cylindrical shank. Overall length is 1.5 inches. The two-flute, right-hand spiral design at a 30-degree helix angle promotes efficient chip evacuation in tight geometries. This tool is uncoated and centercutting, making it capable of plunge entry as well as peripheral and slot milling.\u003c\/p\u003e\u003cp\u003eThe SR-2-015 is suited for mold and die work, aerospace components, medical device machining, and any application requiring fine detail cuts in ferrous and non-ferrous materials. Its regular-length geometry fits standard micro-machining setups on CNC machining centers and high-speed spindles. The Series SR-2 designation indicates a two-flute short-flute carbide configuration optimized for small-diameter work where tool deflection and runout control are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.015-inch cutting diameter with tight mill diameter tolerance of plus 0.0005 and minus 0.0005 inches for consistent sizing\u003c\/li\u003e\n\u003cli\u003eSolid carbide Tuffy grade construction for high rigidity and wear resistance at micro scale\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral design with 30-degree helix angle for efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge milling as well as slot and profile cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation for standard CNC spindle use\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 1\/8-inch shank fits common micro-tool collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard micro end mill replacement for CNC machining centers and high-speed spindle setups accepting a 1\/8-inch straight-cylindrical shank in the ROBBJACK SR-2 series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and locked out before changing tooling. Use a precision collet or shrink-fit holder sized for the 1\/8-inch shank to minimize runout, which is especially critical at 0.015-inch cutting diameters. Verify tool projection and runout with a dial indicator before initiating any cutting cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0005 \/ minus 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.045 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: minus 0.0001 \/ minus 0.0002 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\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.040 \/ minus 0.040 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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCentercutting\u003c\/strong\u003e: Yes\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: SR-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: SR-2-015\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":52024612061490,"sku":"SR-2-015","price":47.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee17f1a62b14df315af2b212cd542090_8fa7666c-608c-4c89-bb34-ddc0f907d721.jpg?v=1790014919","url":"https:\/\/voomisupply.com\/products\/robbjack-sr-2-015-square-end-mill-0-015-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
