Built from micrograin solid carbide, it offers the rigidity and edge retention needed for aggressive cutting parameters. The 0.1875-inch diameter cutting head features three flutes with a right-hand spiral and a 40-degree helix angle, promoting efficient chip evacuation and reduced heat buildup at the cutting zone. An AlTiN coating adds thermal resistance and surface hardness, extending tool life in high-temperature cutting conditions. This tool is installed and used by machinists and tooling professionals in CNC milling applications.\u003c\/p\u003e\n\u003cp\u003eThis ball end mill is suited for 3D contouring, profiling, slotting, and finishing passes on hardened steels, alloy steels, stainless, and similar materials. The 0.625-inch length of cut provides adequate reach for shallow-to-moderate depth passes, while the 0.1875-inch shank diameter allows direct mounting in standard collets and tool holders sized for 3\/16-inch tooling. The 2-inch overall length keeps the tool compact for rigid setups in vertical and horizontal CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides thermal resistance and extended tool life in dry and high-speed cutting\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle with right-hand flute direction promotes smooth chip flow\u003c\/li\u003e\n  \u003cli\u003eThree-flute geometry balances chip clearance with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with 0.625-inch length of cut and 2-inch overall length\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for 3\/16-inch shank ball end mills in standard ER collets, end mill holders, and shrink-fit tooling systems accepting 0.1875-inch shank diameters.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and CNC setup technicians. Ensure the machine spindle is fully stopped and locked before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention nut to the tool holder specification. Verify runout with a dial indicator before beginning a cutting program, as excessive runout will accelerate edge wear on small-diameter carbide end mills.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 inches\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: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\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\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\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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: 12184339\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750113968434,"sku":"12184339","price":35.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07080c64f03a3f82479fdd606f9d3170.jpg?v=1788913670","url":"https:\/\/voomisupply.com\/products\/accupro-12184339-ball-end-mill-0-1875-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
