Manufactured from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding production environments. The 40-degree right-hand helix promotes efficient chip evacuation and reduces chatter during aggressive cuts. With a bright, uncoated finish, this end mill suits applications where coating buildup is a concern or where regrinding is anticipated. It is sized at 7\/16 inches in diameter with a 7\/8-inch length of cut, making it well suited to slotting, profiling, and peripheral milling in tight workspaces.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers, knee mills, and manual milling machines where a 1\/2-inch shank is the standard collet size. The double-end configuration extends usable tool life, allowing machinists to flip and run the second cutting end before retiring the tool. With a regular-length designation and a 4-inch overall length, it fits standard tool holders without extended-reach adapters. Typical users include machinists and toolroom professionals working in job shops, aerospace component manufacturing, and general metalworking.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eDouble-end design doubles usable cutting life per tool\u003c\/li\u003e\n  \u003cli\u003e40-degree right-hand helix angle promotes smooth chip flow and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable, allowing plunge entry into workpieces\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTight mill diameter tolerance of +0.000 \/ -0.002 inches for consistent fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/2-inch collets and end mill holders on CNC and manual milling machines.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet to the minimum engagement depth recommended by the holder manufacturer to prevent tool pullout. Inspect both cutting ends for chipping or damage before use, particularly when switching to the second end.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inches (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Double End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -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 Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\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: 12185140\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732336116018,"sku":"12185140","price":115.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a2e58b13887f07d23a34efd21149265.jpg?v=1788741771","url":"https:\/\/voomisupply.com\/products\/accupro-12185140-square-end-mill-7-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
