It features a 0.2812 inch (9\/32 inch) cutting diameter and a 0.75 inch length of cut, with a 4-flute spiral geometry that promotes efficient chip evacuation and smooth surface finishes. The tool is manufactured from micrograin solid carbide, which delivers superior hardness and heat resistance compared to high-speed steel alternatives. A 40-degree helix angle supports aggressive chip removal while maintaining cutting edge stability. Applied nACRo coating reduces friction and extends tool life in demanding applications. Installed by machinists and CNC operators in job shops, tool rooms, and production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling operations on ferrous and non-ferrous metals, hardened steels, stainless, and similar materials where a tight tolerance and fine surface finish are required. The right-hand cutting and right-hand flute direction make it compatible with standard CNC machining center spindles and manual mills. The 5\/16 inch shank fits standard collet chucks and end mill holders commonly used in vertical machining centers and knee mills. It is a single-end tool, meaning the cutting geometry is on one end only, which is the standard configuration for precision profiling and finishing passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.2812 inch (9\/32 inch) ball end cutting diameter for contour and profile milling\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral geometry for improved surface finish and chip flow\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for hardness and thermal stability\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle balances cutting efficiency with edge strength\u003c\/li\u003e\n  \u003cli\u003enACRo coating reduces friction and extends tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.000 to -0.002 inches for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or new-stock selection for CNC machining centers and manual mills using standard 5\/16 inch collet chucks or end mill holders with right-hand spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank fully into the collet or end mill holder to the recommended engagement depth and torque the retention hardware per the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use, as carbide tools are brittle and susceptible to breakage if dropped or improperly handled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2812 inches (9\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eEnd Configuration\u003c\/strong\u003e: Single End\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\u003c\/strong\u003e: nACRo\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\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\u003eWeight\u003c\/strong\u003e: 0.25 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: 12179230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733016740146,"sku":"12179230","price":73.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee82fc6eb7f8370f036a4008b5538dc4_8623062f-df50-411e-9f16-54df9228103f.jpg?v=1788750513","url":"https:\/\/voomisupply.com\/products\/accupro-12179230-ball-end-mill-0-2812-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
