With a 3\/64 inch (0.0470 inch decimal) ball nose diameter and a stub-length reach of 0.0700 inches, this single-end tool is built for tight-tolerance work in confined pockets and contoured surfaces. The three-flute geometry with a 30-degree right-hand spiral helix supports both roughing and finishing passes. An AlTiN PVD coating adds heat and wear resistance, extending tool life in ferrous materials. The 1\/8 inch straight-cylindrical shank fits standard collets commonly found in CNC machining centers and high-speed spindles. Machinists and tool and die professionals working in precision component manufacturing will find this tool suited to demanding small-feature work.\u003c\/p\u003e\n\u003cp\u003eThis miniature ball end mill is intended for use on ferrous workpiece materials including steel, stainless steel, and cast iron. Its stub-length configuration provides rigidity during small-diameter milling operations where deflection and runout must be minimized. The 1-1\/2 inch overall length and 1\/8 inch shank make it compatible with standard miniature toolholding setups. It is well-suited for finish contouring, radius generation, and pocket milling on precision parts in aerospace, medical, mold and die, and general machining applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/64 inch (0.0470 inch) ball nose diameter with a nose radius of 0.0235 inches for fine contour work\u003c\/li\u003e\n  \u003cli\u003eThree-flute spiral geometry supports both roughing and finishing material removal\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides elevated heat resistance for cutting steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand helix with right-hand cutting direction for smooth chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStub-length reach (0.0700 inches) maximizes rigidity and minimizes deflection at small diameters\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers consistent dimensional accuracy and long tool life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and high-speed spindles with 1\/8 inch collet or toolholder capacity.

Ensure the spindle and toolholder are clean and free of runout before seating the 1\/8 inch shank. At sub-1\/8 inch cutting diameters, even minor runout can cause premature tool breakage; verify TIR with a dial test indicator before cutting. This tool does not support coolant-through delivery; apply flood or mist coolant externally as appropriate for the workpiece material.\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 (0.0470 inch decimal, 1.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.0700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0235 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches), Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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 (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0005 \/ -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 823447-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51748018946354,"sku":"823447-C3","price":61.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4554b3f94a5d0cb64c40eb2d2d45cdda_6b3fb734-8468-45b0-8349-63ca13230fe9.jpg?v=1788888090","url":"https:\/\/voomisupply.com\/products\/harvey-tool-823447-c3-ball-end-mill-3-64-in-3-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
