The tool is ground from micrograin solid carbide for rigidity and edge retention at elevated cutting speeds. A 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces. The ZrN (zirconium nitride) coating adds surface hardness and heat resistance, extending tool life in demanding applications. With a 3\/4-inch diameter and 1-5\/8-inch length of cut, this mill suits moderate-depth passes on machining centers and CNC mills. Right-hand cutting and right-hand spiral flute direction are standard for conventional CNC setups.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for job shops, production machining, die-and-mold work, and toolroom applications where accurate ball-nose profiling is required. The 3\/4-inch shank diameter fits standard ER collets, milling chucks, and shrink-fit holders commonly found on vertical and horizontal machining centers. The single-end geometry and 4-inch overall length allow reach into moderate-depth pockets without excessive tool deflection. It is installed and operated by machinists and CNC programmers on milling equipment requiring controlled surface-finish passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for superior rigidity and cutting-edge retention\u003c\/li\u003e\n\u003cli\u003eZrN coating provides elevated hardness and thermal resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes smooth chip flow and reduces cutting pressure\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with right-hand spiral flutes — compatible with standard CNC spindle direction\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for consistent dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 2 flutes suited for finishing and semi-finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/4-inch toolholders including ER collet chucks, milling chucks, and shrink-fit systems on CNC vertical or horizontal machining centers.

Power down and lock out the spindle before seating or removing the tool from its holder. Verify holder runout with a dial indicator before cutting, as excessive runout accelerates edge wear on carbide tooling. Follow machine-tool manufacturer torque specifications for collet nuts and chuck retention screws — do not overtighten.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 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: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\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: 313707\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730108383538,"sku":"313707","price":391.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b672a1292db384997a286de441b3e1d4.jpg?v=1788711875","url":"https:\/\/voomisupply.com\/products\/accupro-313707-ball-end-mill-3-4-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
