With a 0.031-inch mill diameter, a 0.0465-inch length of cut, and a 1\/8-inch straight-cylindrical shank, this stub-length tool is built for high-accuracy passes where rigidity and runout control matter. The 30-degree helix spiral flute geometry promotes efficient chip evacuation. It is a centercutting design, allowing plunge entry. Licensed machinists and CNC operators working in tool-and-die, mold making, and precision part production are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill suits applications requiring very small-diameter cutting in ferrous and non-ferrous materials. Its stub-length profile minimizes deflection during aggressive passes in confined cavities or fine-feature pocketing. The uncoated solid carbide construction in ROBBJACK's Tuffy material grade makes it appropriate for shops that apply their own coatings or require a bare carbide edge for specific material compatibility. Right-hand cut and right-hand flute orientation are standard for conventional CNC spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.031-inch (1\/32 inch) mill diameter with plus or minus 0.0005-inch diameter tolerance\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction, Tuffy material grade  -  uncoated\u003c\/li\u003e\n\u003cli\u003e2-flute, spiral flute, stub-length design for maximum rigidity at small diameters\u003c\/li\u003e\n\u003cli\u003eCentercutting  -  capable of direct plunge entry\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute; straight-cylindrical 1\/8-inch shank\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style precision cutting tool in the ROBBJACK SS-2 series, compatible with CNC machining centers and manual mills equipped with a collet or chuck accepting a 1\/8-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists or CNC setup technicians. Ensure the spindle and collet are clean and within tolerance before seating the shank; shank diameter tolerance on this tool is -0.0001 to -0.0002 inches. Secure the tool to the manufacturer-recommended collet torque spec for the holder in use  -  do not reference values not provided with the holder. At this diameter, feed rates and spindle speeds must be carefully calculated to avoid tool breakage; consult a speeds-and-feeds reference appropriate for the workpiece material before cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.031 inches (1\/32 inch)\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: 0.0465 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Tuffy Grade, Uncoated\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\u003eLength Type\u003c\/strong\u003e: Stub\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-2-031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":52054509224242,"sku":"SS-2-031","price":38.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/659b70b92e6d3e7b709d7c97795ee06a_3fa77eed-2316-4084-9d97-bc1c2f6cb883.jpg?v=1790036951","url":"https:\/\/voomisupply.com\/products\/robbjack-ss-2-031-square-end-mill-1-32-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
