With a 3\/64 inch (0.0470 inch decimal) cutting diameter and a 35-degree helix angle, this single-end mill delivers both roughing and finishing capability in one tool. The tapered reach neck geometry makes it well suited for deep-cavity mold work where clearance is critical. An AlTiN Nano PVD coating provides thermal resistance and wear protection during aggressive cuts in ferrous and hard workpiece materials. This tool is handled by machinists and toolmakers working on CNC machining centers and milling machines.\u003c\/p\u003e\n\u003cp\u003eThis end mill belongs to the HARVEY TOOL High Helix End Mills for Medium Alloy Steels series, specifically the Ball Tapered Reach Mold Cutter line. It is intended for use on steel and hard material (ISO P and H classifications) as primary workpiece materials, with stainless steel and cast iron (ISO M and K) as secondary applications. The tapered reach neck and stub-length flute configuration make it a practical choice for finishing detailed contours and pockets in injection molds, die components, and similar precision machined parts where tool runout and deflection must be minimized.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/64 inch (0.0470 inch decimal, 1.20 mm) ball nose cutting diameter with a 0.0235 inch nose radius\u003c\/li\u003e\n  \u003cli\u003eAlTiN Nano PVD coating for extended tool life in steel, hard alloys, stainless steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003e35-degree helix angle optimized for medium alloy steels and hard materials\u003c\/li\u003e\n  \u003cli\u003eTapered reach neck with 0.827 inch neck length and 0.865 inch reach length for deep-cavity mold and die work\u003c\/li\u003e\n  \u003cli\u003e2-flute, right-hand cut, right-hand spiral geometry with straight cylindrical 1\/4 inch shank\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and dimensional stability at small diameters\u003c\/li\u003e\n  \u003cli\u003eSingle-end design rated for both roughing and finishing operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills with a standard 1\/4 inch collet or tool holder.

Seat the 1\/4 inch straight shank fully into a precision collet or end mill holder and torque to the tool holder manufacturer specification before use. Verify runout at the cutting diameter before starting the program, as runout errors are amplified at small diameters. Follow all machine-specific lockout and tool-change procedures when loading or unloading the tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 3\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.0470 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter (Metric)\u003c\/strong\u003e: 1.20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0010 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\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.0380 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.827 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.865 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches (1\/4 inch), h6 tolerance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN Nano (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Hard Material (ISO P, H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Cast Iron (ISO M, K)\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\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: 40447-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51742166745394,"sku":"40447-C6","price":126.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6383b5c8e6434a8a97c1e9c360000e5a.jpg?v=1788835719","url":"https:\/\/voomisupply.com\/products\/harvey-tool-40447-c6-ball-end-mill-3-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
