Built from micrograin solid carbide and coated with AlTiCrN, it delivers high heat and wear resistance at elevated cutting speeds. The 4-flute, 38-degree variable-index helix geometry improves chip evacuation and reduces chatter. With a 5\/8-inch diameter and 1-1\/4-inch length of cut, it suits medium-depth finishing and semi-finishing passes. Machinists and tool-and-die professionals install this mill in CNC machining centers requiring tight tolerances and consistent surface finish.\u003c\/p\u003e\n\u003cp\u003eThe 311214 is suited for milling hardened steels, stainless, and high-temperature alloys in both production and job-shop environments. The AlTiCrN coating extends tool life in dry or minimal-lubrication cutting conditions. The straight-cylindrical shank fits standard 5\/8-inch collets and end mill holders. With a 3-1\/2-inch overall length and standard length classification, it fits a wide range of CNC vertical and horizontal machining center setups without requiring extended-reach toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiCrN coating for high-temperature wear and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle with variable index for reduced chatter and improved finish\u003c\/li\u003e\n  \u003cli\u003e4-flute single-end ball profile for contour and 3D surface milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting and right-hand flute direction for standard CNC spindle use\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for compatibility with collet chucks and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank replacement end mill for CNC machining centers using 5\/8-inch collets or end mill holders.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the holder and torque retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning any cutting operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches \/ 15.87 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (31.75 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches (88.90 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: AlTiCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\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 \/ -0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Standard\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: 311214\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748748034354,"sku":"311214","price":234.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f810ad6555de297c62107c97a4f2c394.jpg?v=1788897740","url":"https:\/\/voomisupply.com\/products\/accupro-311214-ball-end-mill-5-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
