It carries a 3\/16 inch (0.1875 inch) mill diameter with a matching 3\/16 inch straight-cylindrical shank, a 5\/16 inch length of cut, and a 2 inch overall length. The AlTiN PVD coating improves heat resistance and tool life during ferrous machining. The 30-degree right-hand spiral flute geometry supports both roughing and finishing passes. This tool is sized for miniature and precision milling work and is typically installed and operated by machinists and toolroom professionals on CNC milling machines.\u003c\/p\u003e\u003cp\u003eThe 51012-C3 fits into miniature end mill applications where tight tolerances and small-feature geometry are required. It is well suited for die and mold work, aerospace components, and precision part machining in steel and stainless steel. With a stub-standard length profile, it offers increased rigidity compared to longer reach tools, making it effective for slotting, profiling, and contour milling in confined workpiece features. The single-end configuration is standard for this class of carbide end mill.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating for elevated heat resistance during steel and stainless steel milling\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral design supports both roughing and finishing operations\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting efficiency and chip evacuation\u003c\/li\u003e\n\u003cli\u003eStub-standard length profile maximizes rigidity in small-feature milling setups\u003c\/li\u003e\n\u003cli\u003e0.0938 inch nose radius ball profile for accurate contour and 3D surface work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style miniature ball end mill for use in CNC milling operations on steel, stainless steel, and cast iron workpieces, consistent with the Harvey Tool Miniature End Mills - Ball - Stub Standard series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists following standard CNC tooling procedures. Power down and lock out the spindle before changing tooling. Verify that the tool holder bore matches the 3\/16 inch shank diameter before seating the tool. Do not exceed the manufacturer-rated speeds and feeds for the workpiece material and coating combination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0938 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.3120 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\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\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51012-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51727144354098,"sku":"51012-C3","price":56.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4554b3f94a5d0cb64c40eb2d2d45cdda.jpg?v=1788673989","url":"https:\/\/voomisupply.com\/products\/harvey-tool-51012-c3-ball-end-mill-3-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
