It features a 0.037-inch cutting diameter, a 0.111-inch length of cut, and a 1\/8-inch shank diameter, making it well-suited for fine detail work in metal, composite, and plastic materials. The two-flute spiral design with a 30-degree helix angle promotes chip evacuation and smooth cutting at high feed rates. At 1.5 inches overall length, this is a compact, rigid tool built for accuracy in close-tolerance applications. It is uncoated and ships as a single-end tool. Machinists and CNC operators in precision machining, tool and die, mold making, and production environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for slotting, profiling, and plunge-capable operations on small features where a standard-diameter tool will not fit. Its centercutting geometry allows direct plunge entry without a pre-drilled hole. The right-hand cut and right-hand flute configuration is standard for conventional CNC milling spindles. It is most commonly used in vertical machining centers and CNC mills running small-diameter toolpaths for detailed workpiece features, miniature components, or precision cavities in production and prototype environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.037-inch cutting diameter for fine detail and small-feature milling\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding materials\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral design with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute  -  compatible with standard CNC milling spindles\u003c\/li\u003e\n  \u003cli\u003eUncoated finish; suitable for use as-delivered or with operator-selected coating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision cutting tool for use in CNC vertical machining centers and manual mills accepting a 1\/8-inch shank diameter collet or tool holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Secure the shank in a properly sized collet or end mill holder, verifying runout is within acceptable limits before beginning a cut. At this diameter, tool deflection and breakage risk increase significantly with excessive feed rates or improper workholding  -  confirm speeds and feeds match the material and tool specifications before running.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.037 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: 0.111 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: -0.0001 \/ -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: +0.040 \/ -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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\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\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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-2-037\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":51971149201714,"sku":"SR-2-037","price":40.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c4d9f1ef135e2f773eefe3d48988b72.jpg?v=1789953590","url":"https:\/\/voomisupply.com\/products\/robbjack-sr-2-037-square-end-mill-0-037-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
