Built from micrograin solid carbide, it delivers the hardness and wear resistance needed for ferrous and non-ferrous material removal. The 3-flute geometry with a 30-degree helix spiral flute provides a balance of chip evacuation and surface finish quality. A titanium carbonitride (TiCN) coating adds surface hardness and reduces friction at the cutting edge. At 3\/64 inch (0.0469 inch) cutting diameter with a 3\/32 inch length of cut, this stub-length end mill is sized for fine-detail work in tight geometries. Machinists and tool-and-die professionals install and use this tool in CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finish milling, slotting, and contour work in small-feature applications. The stub length profile and 1\/8 inch shank diameter make it appropriate for high-speed spindles and micro-machining setups where rigidity and runout control are critical. The centercutting design allows plunge entry, expanding its use in pocketing and ramp-entry toolpaths. Typical applications include mold and die work, aerospace components, and precision part manufacturing where small-diameter tooling and tight tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for hardness and extended tool life\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and improves wear resistance at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e3-flute, 30-degree helix spiral flute for balanced chip flow and finish quality\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables plunge cutting and ramp entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eStub length profile maximizes rigidity in small-diameter tooling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in CNC machining centers and manual milling machines accepting a 1\/8 inch straight shank collet or tool holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists into a collet or end mill holder sized for a 1\/8 inch shank. Ensure the spindle is fully stopped and locked out before changing tooling. Verify runout at the spindle nose before securing the tool, as small-diameter carbide end mills are sensitive to collet concentricity. Handle carbide tooling carefully to avoid chipping the cutting edges during installation and storage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/64 inch (0.0469 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/32 inch (0.0938 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inch (1.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0002 \/ -0.0008 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12178903\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51751153566002,"sku":"12178903","price":22.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/325e345a10579b9a7e6ce6302c1a7969.jpg?v=1788921931","url":"https:\/\/voomisupply.com\/products\/accupro-12178903-square-end-mill-3-64-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
