With a 1\/4 inch cutting diameter and a 1 inch length of cut, this single-end tool delivers precise, flat-bottomed profiles in demanding machining environments. The CVD diamond coating provides exceptional hardness and wear resistance, making it well-suited for cutting graphite, carbon fiber, fiberglass, ceramics, and other non-ferrous abrasive materials. Four right-hand flutes with a 30-degree helix angle contribute to efficient chip evacuation and surface finish quality. Licensed machinists and CNC operators use this tool in production and job-shop settings where tool life in abrasive materials is a priority.\u003c\/p\u003e\u003cp\u003eThis end mill is built for dry or near-dry machining of composites, reinforced plastics, graphite, and similar non-metallic abrasive materials. The CVD diamond coating is not intended for ferrous metals. It fits standard 1\/4 inch collets and tool holders, making it easy to deploy on vertical machining centers, CNC routers, and similar platforms. It is a single-end, non-centercutting tool, meaning it is designed for peripheral and slot milling rather than plunge cutting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD diamond coating for extreme wear resistance in abrasive and composite materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003e4 right-hand flutes with 30-degree helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e1\/4 inch shank matches standard collet and toolholder sizes\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003eNon-centercutting design suited for peripheral and slotting operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4 inch collet chucks and end mill holders on CNC machining centers and routers; intended for non-ferrous and abrasive materials such as graphite, carbon fiber, and fiberglass composites.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully in the collet or tool holder and torque the retention hardware per the toolholder manufacturer specifications. CVD diamond-coated tools should not be used on ferrous materials, as this will cause rapid coating degradation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\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 (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\/Finish\u003c\/strong\u003e: CVD Diamond\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\u003eVariable Helix\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\u003ePackage Dimensions\u003c\/strong\u003e: 4.25 inches L x 0.51 inches W x 0.51 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 871316\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728176972082,"sku":"871316","price":283.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8ec0c7d1b391b5008bbc46e0347b545_5c5f9b1b-d01e-489d-806d-8afe26c680eb.jpg?v=1788689018","url":"https:\/\/voomisupply.com\/products\/harvey-tool-871316-square-end-mill-1-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
