With a 3\/64 inch (0.0470 inch decimal) mill diameter, 2-flute spiral geometry, and a 20-degree right-hand helix, this single-end tool is built for tight-tolerance finish passes where surface quality and dimensional accuracy are critical. The AlTiN Nano PVD coating provides thermal resistance and extended tool life in abrasive cutting environments. Overall length is 2.5 inches with a 1\/4 inch straight-cylindrical shank. The stub length type and extended reach design make it well suited for fine detail work in hardened workpieces.\u003c\/p\u003e\u003cp\u003eThis end mill is part of the Harvey Tool End Mills for Hardened Steels - Finishers - Ball series and is intended for finishing passes on hard materials, with secondary suitability for steel, stainless steel, and cast iron. Typical applications include mold and die work, tooling repair, and precision contouring in CNC machining centers where small-diameter ball end geometry is required. It is not designed for roughing operations or soft non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN Nano PVD coating for heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e2-flute right-hand spiral geometry optimized for finishing passes\u003c\/li\u003e\n\u003cli\u003e0.0235 inch nose radius with 0.0330 inch neck length for fine detail access\u003c\/li\u003e\n\u003cli\u003eExtended reach design with 0.0710 inch reach length (1.80 mm)\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.0000 \/ -0.0006 inches for tight dimensional control\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 1\/4 inch shank with h6 shank diameter tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining applications involving hard materials, steel, stainless steel, and cast iron.

Secure the shank in a compatible collet or end mill holder rated for the 1\/4 inch shank diameter before spindle engagement. Verify runout at setup, as small-diameter carbide tooling is sensitive to fixture concentricity. Do not use this tool for interrupted cuts or roughing passes, as the solid carbide construction is brittle under high lateral shock loads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 3\/64 inches\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 (mm)\u003c\/strong\u003e: 1.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eHelix Angle\u003c\/strong\u003e: 20 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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0235 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.0330 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.0710 inches (1.80 mm)\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0006 inches\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\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 37847-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51739599372594,"sku":"37847-C6","price":118.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17fe705d03cc150ca73779bd2757e690_7920e302-72e4-4daa-8720-7fa56a585e66.jpg?v=1788816769","url":"https:\/\/voomisupply.com\/products\/harvey-tool-37847-c6-ball-end-mill-3-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
