With a 0.042-inch cutting diameter and a 0.063-inch length of cut, this stub-length tool is built for shallow-profile work where rigidity and accuracy matter. The 2-flute geometry and 30-degree helix angle promote efficient chip evacuation in a wide range of materials. The straight cylindrical shank measures 0.125 inches in diameter and fits standard collet toolholders. Centercutting capability allows direct plunge entry without a pre-drilled hole. Licensed machinists and CNC operators handling precision aerospace, medical, or micro-component work are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThe SS-2-042 is suited for milling operations on small-feature components where a sub-0.050-inch tool diameter is required. Its stub length minimizes deflection during aggressive lateral passes. The uncoated solid carbide construction in ROBBJACK Tuffy material grade performs well in non-ferrous metals, plastics, and some hardened steels when used within recommended surface footage and feed rate parameters. Right-hand cut and right-hand flute orientation are standard for conventional CNC milling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.042-inch cutting diameter with tight tolerance of plus 0.0005 \/ minus 0.0005 inches for repeatable precision\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction in Tuffy material grade for wear resistance and rigidity\u003c\/li\u003e\n  \u003cli\u003e30-degree helix spiral flute for efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge milling without pilot hole\u003c\/li\u003e\n  \u003cli\u003eStub-length profile reduces tool deflection in shallow-depth milling applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with a 0.125-inch collet or toolholder accepting a straight cylindrical shank.

Secure the 0.125-inch shank firmly in a matched collet or end mill holder to the manufacturer-recommended clamping procedure. Avoid extending the tool beyond its designed stub-length profile, as excessive overhang will increase deflection and risk breakage at this small diameter. Verify runout with a dial indicator before production cuts when working at sub-0.050-inch diameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.042 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting 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: 0.063 inches (1\/16 inch)\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\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\u003eCoating\u003c\/strong\u003e: 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\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: SS-2-042\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":52056688853298,"sku":"SS-2-042","price":38.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/659b70b92e6d3e7b709d7c97795ee06a_97cd8495-f5d2-46df-8595-f769c12955af.jpg?v=1790038393","url":"https:\/\/voomisupply.com\/products\/robbjack-ss-2-042-square-end-mill-0-042-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
