Built from micrograin solid carbide, this single-end tool features four spiral flutes with a 40-degree helix angle and a TiCN (Titanium Carbonitride) coating for improved wear resistance and heat dissipation at the cutting edge. The ball nose geometry produces contoured surfaces and 3D profiles with consistent finish quality. It is sized at 0.315 inches (8 mm) in cutting diameter with a 0.7874-inch (20 mm) length of cut, making it suitable for moderate-depth profiling and contouring passes on machining centers and CNC mills.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in ferrous and non-ferrous metal machining where a ball-nose profile is required. Typical applications include die and mold work, contour milling, and 3D surface finishing on CNC machining centers. The 8 mm shank diameter fits standard ER collet chucks and end mill holders commonly found in professional machine shops. Right-hand cutting and right-hand flute direction are standard for conventional CNC milling setups. The regular-length configuration suits most production and toolroom environments without requiring extended reach clearance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves surface hardness and reduces built-up edge\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smoother cutting action\u003c\/li\u003e\n\u003cli\u003eFour spiral flutes deliver improved finish quality on contoured surfaces\u003c\/li\u003e\n\u003cli\u003eBall nose geometry suited for 3D profiling, contouring, and die work\u003c\/li\u003e\n\u003cli\u003eSingle-end design with right-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide ball end mill for CNC machining centers and manual mills equipped with 8 mm collet chucks or end mill holders accepting an 8 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the collet or holder to the recommended gauge depth, and torque the collet nut per the tool holder manufacturer specification. Confirm runout with a dial indicator before beginning cuts, as excessive runout accelerates wear and degrades surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal Inch)\u003c\/strong\u003e: 0.315 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (mm)\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7874 inches (20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.48 inches (63 mm)\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\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: 12184635\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740481519922,"sku":"12184635","price":77.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14e455fe5915a0c419e98340177684b5.jpg?v=1788825298","url":"https:\/\/voomisupply.com\/products\/accupro-12184635-ball-end-mill-0-315-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
