With a 0.052-inch cutting diameter and a 2-flute configuration, this stub-length tool delivers clean square-shoulder cuts and slot milling in small-feature work. The 30-degree helix spiral flute geometry promotes efficient chip evacuation while maintaining edge stability in hard and abrasive materials. Centercutting capability allows direct plunge entry without pre-drilling. The uncoated Tuffy-grade carbide substrate is suited to dry or minimally lubricated cutting conditions where coating adhesion or chemical reactivity is a concern.\u003c\/p\u003e\u003cp\u003eThis end mill is built for precision machining operations where small diameters and close tolerances are required. Typical applications include mold and die work, micro-slot milling, engraving, and fine-feature profiling on CNC machining centers or manual mills. The stub length-of-cut format provides added rigidity at the small diameter, reducing deflection during aggressive passes. Right-hand cut and right-hand flute orientation follow standard CNC tooling conventions. The 1\/8-inch straight cylindrical shank fits standard collets and tool holders common in production and toolroom environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.052-inch cutting diameter with tight tolerance of plus or minus 0.0005 inches for precise feature control\u003c\/li\u003e\n\u003cli\u003e2-flute solid carbide construction in Tuffy material grade for strength at small diameters\u003c\/li\u003e\n\u003cli\u003e30-degree helix spiral flute promotes chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without pilot hole\u003c\/li\u003e\n\u003cli\u003eStub length-of-cut format maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for applications where an uncoated carbide substrate is preferred\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for CNC machining centers and manual mills accepting a 1\/8-inch straight cylindrical shank collet or tool holder.\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 machine power locked out per shop safety procedures. Ensure the collet and tool holder are clean and free of chips before seating the shank. At this diameter, runout control is critical  -  verify collet concentricity before cutting. Follow the tooling manufacturer's recommended speeds and feeds for carbide at the specified diameter and material grade.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.052 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.0005 \/ minus 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.078 inches (5\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\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 (1-1\/2 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\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\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\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-2-052\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":52059580039474,"sku":"SS-2-052","price":38.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/659b70b92e6d3e7b709d7c97795ee06a_bc620849-2d29-4f9e-8b8e-89dba20bfe57.jpg?v=1790040453","url":"https:\/\/voomisupply.com\/products\/robbjack-ss-2-052-square-end-mill-0-052-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
