With a 5-degree taper angle per side and a 1\/4 inch small end diameter, it produces accurate tapered walls and complex curved surfaces in a single pass. The ball end geometry with a 1\/8 inch nose radius allows smooth surface finishes on contoured workpieces. Three right-hand spiral flutes with a 30-degree helix angle promote efficient chip evacuation and reduce cutting forces. Micrograin carbide construction provides hardness and wear resistance suited to demanding cutting conditions. This tool is installed and operated by machinists and CNC programmers working in job shops, mold and die, and aerospace environments.\u003c\/p\u003e\u003cp\u003eThis tapered ball end mill is suited for CNC machining centers and milling machines where tapered cavity walls, mold details, and contoured pocket floors are required. The 1 inch length of cut and 7\/16 inch shank diameter make it appropriate for moderate-depth cavities where rigidity is important. The centercutting design allows plunge entry into workpiece material. Typical materials include aluminum, plastics, and softer steels where uncoated carbide performs reliably without the added friction of a coating.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-degree taper angle per side for precise tapered wall geometry\u003c\/li\u003e\n\u003cli\u003eBall end with 1\/8 inch nose radius for smooth contoured surface finishes\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003e3 right-hand spiral flutes with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eUncoated finish suited for aluminum, plastics, and light ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for CNC milling machines and machining centers accepting a 7\/16 inch round shank end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully powered down and at a complete stop before inserting or removing the tool from the tool holder. Verify the shank is clean and fully seated in a collet or end mill holder rated for the 7\/16 inch diameter before torquing the retention mechanism to the holder manufacturer specification. Confirm runout with a dial indicator before beginning production cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Ball\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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: Uncoated\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: 12177649\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750145687858,"sku":"12177649","price":146.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e2668132bc80363132735e77dca4b90.jpg?v=1788913817","url":"https:\/\/voomisupply.com\/products\/accupro-12177649-tapered-ball-end-mill-1-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
