The tool features a 0.25 inch diameter, a 2 inch length of cut, and a 4 inch overall length with a straight-cylindrical 0.25 inch shank. It runs four helical flutes in a right-hand cutting and flute direction with a variable helix angle, which reduces chatter and promotes smooth chip evacuation during finishing passes. The bright uncoated carbide construction makes it well suited for high-precision milling where surface finish is the primary goal. This is a single-end, long-flute configuration built for tight-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThe 34116 belongs to the Harvey Tool Miniature End Mills - Ball - Long Flute series and is intended for finishing cuts in hard materials rated H, as well as secondary materials including steel (P), stainless steel (M), and cast iron (K). The long flute and 2 inch reach length allow access to deeper pockets and contoured surfaces that shorter end mills cannot reach. It is suited for use in CNC machining centers and high-speed milling applications in tool and die, mold making, aerospace, and precision fabrication environments. The 0.125 inch nose radius produces smooth, accurate ball-end profiles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and ferrous materials\u003c\/li\u003e\n  \u003cli\u003eVariable helix angle reduces chatter and improves surface finish during finishing passes\u003c\/li\u003e\n  \u003cli\u003eLong flute configuration with 2 inch length of cut and 2 inch reach for deep pocket and contoured surface access\u003c\/li\u003e\n  \u003cli\u003eFour right-hand helical flutes promote efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for high-precision finishing where coating buildup is not acceptable\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h6 tolerance for secure toolholder grip\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and direct-fit cutting tool for CNC machining centers accepting a 0.25 inch straight-cylindrical shank.

The machine spindle must be fully stopped and locked out before inserting or removing the tool from the holder. Ensure the shank is fully seated and the holder is torqued to the toolholder manufacturer specification. Confirm runout with a dial indicator before beginning a cut, as excessive runout will reduce tool life and degrade surface finish on finished workpieces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\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\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\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: Bright \/ Uncoated\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\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\u003eLength Type\u003c\/strong\u003e: Long\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 34116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51744559300914,"sku":"34116","price":76.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ec74c2d3cdbfbb41c8ebdef92eaf167_487fa3f0-972b-44d4-bfc6-1d71addf958d.jpg?v=1788858162","url":"https:\/\/voomisupply.com\/products\/harvey-tool-34116-ball-end-mill-0-25-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
