Part of the SS-2 Series, this stub-length, two-flute tool features a 0.028-inch cutting diameter and a 0.042-inch length of cut. The straight cylindrical shank measures 0.125 inches in diameter, and the overall length is 1.5 inches. Built from ROBBJACK Tuffy-grade solid carbide, this end mill delivers the rigidity and wear resistance required for accurate cuts in small-feature machining. It is uncoated and intended for use by machinists and tooling professionals running precision CNC or manual milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for fine-detail milling work where a very small cutting diameter is required, such as engraving, slotting, and contouring in small cavities. The stub-length configuration reduces deflection and improves rigidity at small diameters. The centercutting design allows plunge entry, expanding its usefulness in multi-axis machining setups. Right-hand cut and right-hand spiral flute geometry are standard for conventional milling spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.028-inch cutting diameter with a tight mill diameter tolerance of plus or minus 0.0005 inches\u003c\/li\u003e\n\u003cli\u003eSolid carbide Tuffy-grade construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e2-flute, spiral flute design with a 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eStub-length configuration minimizes deflection at small diameters\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for use with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for CNC and manual milling machines accepting a 0.125-inch straight cylindrical shank, within the ROBBJACK SS-2 Series lineup.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and locked out before changing tooling. Verify collet or chuck bore matches the 0.125-inch shank diameter before securing. Handle micro-diameter carbide end mills with care to avoid chipping the cutting edges during setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.028 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.042 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 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\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-2-028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":52071684505906,"sku":"SS-2-028","price":40.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/659b70b92e6d3e7b709d7c97795ee06a_60892c35-e3c6-4187-881e-f46e183fde96.jpg?v=1790049280","url":"https:\/\/voomisupply.com\/products\/robbjack-ss-2-028-square-end-mill-0-028-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
