With a 0.7874 inch (20 mm) mill diameter and a 1.4961 inch (38 mm) length of cut, this single-end tool generates smooth, accurate contoured surfaces on hardened steels, stainless steels, and other demanding materials. The 4-flute configuration with a 40-degree helix angle promotes efficient chip evacuation and stable cutting action. An AlTiN (aluminum titanium nitride) coating extends tool life by reducing heat buildup and improving wear resistance at elevated cutting temperatures. Micrograin carbide substrate enhances edge retention and toughness.\u003c\/p\u003e\u003cp\u003eThis ball end mill is suited for finish milling, profile milling, and 3D contouring work on CNC machining centers and milling machines in job shop, tool and die, mold making, and production machining environments. The right-hand cutting direction and right-hand spiral flutes are standard for conventional CNC spindle configurations. The 20 mm shank diameter provides rigid tool holding in standard ER or side-lock collet chucks. With a 101 mm overall length, this tool fits most vertical and horizontal machining center spindles without requiring extended-reach toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for superior edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides high-heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e4-flute design with 40-degree helix for efficient chip flow and improved surface finish\u003c\/li\u003e\n\u003cli\u003eBall nose geometry enables accurate 3D contour and profile milling\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with right-hand cut and right-hand spiral flutes\u003c\/li\u003e\n\u003cli\u003e20 mm shank diameter compatible with standard CNC toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual milling machines accepting a 20 mm shank diameter.

Ensure the machine spindle is fully stopped and the machine is in a safe, powered-down state before loading or changing tooling. Seat the shank fully into a properly rated collet chuck or toolholder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production cut to avoid premature tool wear or workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.7874 inches (20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.4961 inches (38 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.976 inches (101 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.7874 inches (20 mm)\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: 40 degrees\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\u003c\/strong\u003e: AlTiN\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 Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 pounds\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: 12184708\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731213222194,"sku":"12184708","price":459.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba86b8b9f2854d9272f9b8f131f45ac8.jpg?v=1788728362","url":"https:\/\/voomisupply.com\/products\/accupro-12184708-ball-end-mill-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
