Built from micrograin solid carbide, it delivers consistent cutting performance in ferrous and non-ferrous materials. The mill features a 1-inch cutting diameter, a 3-inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation and smooth surface finishes. With a 6-inch overall length, this tool falls into the extra-long category, making it suited for deep-cavity and extended-reach applications. It is installed by machinists and tooling technicians operating CNC or manual vertical milling equipment.\u003c\/p\u003e\u003cp\u003eThis end mill is applicable in job shop, production, and tool-and-die environments where deep pocket milling, contour milling, and 3D surface work are performed. The ball-nose geometry generates continuous radial cutting action, making it effective for finishing passes on complex contoured surfaces. The bright uncoated finish is common in applications where coating interaction with the workpiece material is a concern, or where regrinding is anticipated. The right-hand cutting and right-hand flute direction are standard for conventional CNC mill spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch mill diameter with a tight tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e3-inch length of cut for deep-cavity and contour milling passes\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration with 40-degree helix angle for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eExtra-long 6-inch overall length for extended-reach setups\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for regrinding and coating-sensitive applications\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 and manual milling machines accepting a 1-inch straight shank with a shank diameter tolerance of -0.0001 \/ -0.0004 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Power down and lock out the spindle before mounting or removing any end mill. Verify that the tool holder collet or set-screw holder is clean and dimensionally correct for a 1-inch shank before seating the tool. Confirm runout at the tip after mounting to ensure accuracy before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\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: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eLength Type\u003c\/strong\u003e: Extra Long\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 12184889\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733031289138,"sku":"12184889","price":588.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/124fa5a263579d1f1b701b442b9486c7.jpg?v=1788750790","url":"https:\/\/voomisupply.com\/products\/accupro-12184889-ball-end-mill-1in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
