It measures 0.2188 inches in diameter with a 0.4375-inch length of cut and a 2.5-inch overall length. The tool is constructed from solid carbide and features a TiCN (Titanium Carbonitride) coating, which improves surface hardness and wear resistance for extended tool life in demanding cutting conditions. Four spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. This tool is installed and operated by machinists and CNC programmers working on precision parts.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling slots, pockets, contours, and three-dimensional profiles in ferrous and non-ferrous materials. The stub-length flute geometry and 0.25-inch shank diameter make it compatible with standard collet and end mill holders. The right-hand cutting and right-hand flute direction conform to standard CNC milling setups. The double-end design allows the operator to index to the second cutting end when the first end is worn, extending the usable life of the tool before replacement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision machining\u003c\/li\u003e\n  \u003cli\u003eTiCN coating enhances hardness and extends tool life in abrasive cutting environments\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral design with 40-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eDouble-end configuration provides two usable cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC milling setups\u003c\/li\u003e\n  \u003cli\u003eStub-length flute type offers added rigidity for tight-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 0.25-inch collet chucks and end mill holders in CNC machining centers and manual milling machines configured for right-hand 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 spindle is fully stopped and machine power is off before changing tooling. Seat the shank fully into the holder and torque the collet nut or set screw per the holder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2188 inches (7\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.4375 inches (7\/16 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: 0.25 inches (1\/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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\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: Double End\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  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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: 12185362\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729652875570,"sku":"12185362","price":99.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2f7a78a91f2f9aedea1eea5a4134f74.jpg?v=1788707257","url":"https:\/\/voomisupply.com\/products\/accupro-12185362-ball-end-mill-0-2188-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
