Built from micrograin solid carbide, it delivers rigidity and wear resistance well beyond high-speed steel alternatives. The cutting diameter measures 3\/4 inches with a matching 3\/4-inch shank diameter, and the length of cut reaches 3-1\/4 inches — a long-reach configuration suited to deep-cavity and deep-slot applications. A 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces. The ZrN (zirconium nitride) coating adds a hard, low-friction surface layer that extends tool life in non-ferrous metals, graphite, and abrasive composite materials. Right-hand cutting and right-hand flute direction are standard. Installed by machinists and CNC operators in job shops, mold-and-die, and aerospace production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is well suited for deep-pocket milling, sculpted surface finishing, and contour passes where extended reach is required. The long overall length of 6 inches allows access to features that standard-length tools cannot reach without interference. The 2-flute geometry provides chip clearance in softer materials and gummy alloys. The micrograin carbide substrate supports higher surface speeds and feeds in aluminum, copper, plastics, and graphite. This tool is a single-end design, meaning one active cutting end per tool — standard for solid carbide end mills at this diameter and length specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch ball end cutting diameter with 3-1\/4-inch length of cut for deep-reach profiling\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for superior hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eZrN coating extends tool life in non-ferrous metals, composites, and graphite\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute, right-hand cut — compatible with standard CNC spindle rotation\u003c\/li\u003e\n  \u003cli\u003eLong-reach configuration with 6-inch overall length for deep-cavity access\u003c\/li\u003e\n  \u003cli\u003eTight diameter tolerances: mill diameter +0.000 \/ -0.002 inches, shank +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-specification solid carbide ball end mill for CNC machining centers and manual mills accepting a 3\/4-inch straight shank collet or end mill holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. The machine spindle must be fully stopped and locked out before inserting or removing the tool from the holder. Use a calibrated torque wrench and the appropriate collet or end mill holder rated for 3\/4-inch shank tooling — do not overtighten, as this can distort the shank and affect runout. Verify tool runout with a dial indicator after seating; excessive runout accelerates edge wear and reduces surface finish quality on the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\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\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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\u003eFlute 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\u003eExtended Reach\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: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 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: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 313711\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736220598578,"sku":"313711","price":510.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/707cf185c1edd19fb40a4c3a814695e1.jpg?v=1788776589","url":"https:\/\/voomisupply.com\/products\/accupro-313711-ball-end-mill-3-4-in-2-flute-solid-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
