With a 1\/16 inch (0.0625 inch) cutting diameter and a 1\/4 inch length of cut, this end mill is built for tight-tolerance work in small-feature applications. The 42-degree variable helix geometry reduces chatter and improves chip evacuation during cutting. A titanium diboride (TiB2) coating provides surface hardness and lubricity, extending tool life in abrasive materials. This tool is installed and operated by machinists and CNC operators working in job shops, aerospace, medical device, and precision manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for small-diameter slot milling, profiling, and finishing passes where dimensional accuracy is critical. The 3-flute configuration balances chip clearance with tool rigidity at this diameter range. The 1\/8 inch shank diameter fits standard collets and tool holders commonly found on CNC machining centers and high-speed spindles. The non-centercutting design means it is intended for side milling and peripheral cuts rather than direct plunge entry. Right-hand cut and right-hand flute direction are standard for conventional CNC setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/16 inch cutting diameter with 1\/4 inch length of cut for small-feature precision milling\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance at small diameters\u003c\/li\u003e\n\u003cli\u003e42-degree variable helix reduces vibration and improves surface finish\u003c\/li\u003e\n\u003cli\u003eTitanium diboride (TiB2) coating increases hardness and reduces friction\u003c\/li\u003e\n\u003cli\u003e3-flute design balances chip evacuation and core strength\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute, single end configuration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and high-speed spindles accepting a 1\/8 inch shank diameter via standard collet or end mill holder.

The tool should be secured in a properly sized collet or end mill holder and torqued to the toolholder manufacturer's specifications before operation. Confirm spindle runout is within acceptable limits before cutting, as runout at this diameter can significantly affect tool life and part accuracy. Always power down and lock out the machine spindle before changing tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/4 inch (0.25 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: Titanium Diboride (TiB2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes, 42 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 Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 857262-C8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51730074599730,"sku":"857262-C8","price":83.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304bf5d2d4b4c086e10ee0a3408ee724_786a5ab7-02c9-4fa3-af4d-cc1810443867.jpg?v=1788711291","url":"https:\/\/voomisupply.com\/products\/harvey-tool-857262-c8-square-end-mill-1-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
