With a 0.2756-inch (7 mm) mill diameter and a 0.748-inch (19 mm) length of cut, this tool handles profiling, contouring, and three-dimensional surface work where a radiused cutting edge is required. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Micrograin carbide construction delivers edge retention and rigidity at small diameters. The uncoated finish makes it suitable for applications where coating compatibility or re-sharpening frequency is a factor. Machinists and tooling specialists will find this end mill well-suited for tight-tolerance finish cuts.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers, knee mills, and manual milling machines capable of holding an 8 mm (0.315-inch) shank. It is a single-end tool with right-hand cutting direction and right-hand flute spiral, making it compatible with standard spindle rotation. Typical applications include die and mold work, part profiling, cavity milling, and contour finishing in ferrous and non-ferrous materials. The 63 mm (2.48-inch) overall length keeps overhang manageable for improved rigidity at this diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for extended edge life and rigidity at small diameters\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes chip evacuation and reduces heat buildup during cuts\u003c\/li\u003e\n  \u003cli\u003eBall end geometry enables profiling, contouring, and 3D surface milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flutes match standard CNC and manual mill spindle rotation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suits applications requiring re-sharpening or coating-sensitive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with 8 mm shank fits standard collets and tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and milling machines equipped with ER collets, end mill holders, or other tooling systems that accept an 8 mm round shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the retention hardware according to the tool holder manufacturer's specifications. Verify runout with a dial indicator before commencing cuts, as runout at small diameters has a disproportionate effect on tool life and surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2756 inches (7 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.748 inches (19 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\u003eShank Diameter\u003c\/strong\u003e: 0.315 inches (8 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\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\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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\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: 12183971\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743273615666,"sku":"12183971","price":70.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/58d48e374a61d1e47febc4fc52ae7737.jpg?v=1788844876","url":"https:\/\/voomisupply.com\/products\/accupro-12183971-ball-end-mill-0-2756-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
