Built with a 1-inch diameter, 3-flute configuration, and a 37-degree helix angle, it delivers efficient chip evacuation and smooth cutting action. The chipbreaker geometry reduces cutting forces and controls chip size during heavy passes. A ZrN (zirconium nitride) coating provides enhanced wear resistance and lubricity, extending tool life in ferrous and non-ferrous applications. This end mill is suited for use by machinists and tool-and-die professionals operating CNC mills, VMCs, and manual knee mills.\u003c\/p\u003e\u003cp\u003eThis tool is intended for applications requiring both roughing and finishing passes without a tool change. The 2-inch length of cut accommodates moderate-depth pocketing, slotting, and peripheral milling. The straight shank with a 1-inch diameter fits standard ER, CAT, BT, and direct-fit toolholders commonly found in production and job-shop environments. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC milling operations. The single-end design and micrograin carbide substrate make it well-suited for harder workpiece materials and higher-speed machining programs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eChipbreaker geometry reduces cutting forces and controls chip size during roughing passes\u003c\/li\u003e\n\u003cli\u003eZrN coating improves wear resistance and reduces built-up edge in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e37-degree helix angle promotes smooth chip flow and stable cutting\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eSingle-end, straight-shank construction for direct toolholder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide end mill for standard 1-inch straight-shank toolholders used in CNC and manual milling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Secure the straight shank in a properly sized collet or end mill holder, ensuring the shank is seated to the minimum insertion depth recommended for the holder. Verify runout with a dial indicator before beginning a production cut. Always power down and lock out the spindle before changing or adjusting tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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 (OAL)\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 95171857\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731539591474,"sku":"95171857","price":879.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a251811e72f944e1b5df9a4e56ec8869.jpg?v=1788732315","url":"https:\/\/voomisupply.com\/products\/accupro-95171857-roughing-finishing-end-mill-1in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
