It features a 1\/2 inch cutting diameter, a 2 inch length of cut, and a 40-degree helix angle that promotes smooth chip evacuation and reduces cutting forces. The AlTiN coating improves heat resistance and extends tool life in demanding cutting conditions. With three flutes and a right-hand spiral flute geometry, this end mill balances rigidity with chip clearance. It is used primarily by machinists and toolroom professionals on CNC mills and manual milling machines.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for long-reach milling operations where standard-length tooling cannot access the full depth of a feature. The 4 inch overall length and 2 inch length of cut place it in the long-length category, making it appropriate for deep pocket milling, slotting, and profile work. The centercutting capability allows plunge entry directly into the workpiece without a pre-drilled hole. Typical applications include job shop machining, die and mold work, and general-purpose CNC production milling in metalworking environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate for wear resistance and edge integrity\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish for elevated heat resistance in high-speed and dry cutting\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip flow and reduced cutting pressure\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pilot drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute with spiral flute geometry for standard CNC compatibility\u003c\/li\u003e\n  \u003cli\u003eLong-length configuration with 2 inch length of cut for deep-feature access\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for standard 1\/2 inch shank square end mill toolholders including ER collet chucks, shrink-fit holders, and Weldon-style side-lock holders accepting a 1\/2 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and machine power is off or in an e-stop state before loading or changing tooling. Insert the shank to the recommended engagement depth specified by the toolholder manufacturer and verify runout with a dial indicator before beginning a cut. Do not exceed the tool manufacturer's recommended depth of cut or feed rate for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches (2.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches (4.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\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 Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\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\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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: 12179745\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738648084786,"sku":"12179745","price":123.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c33b044a3bfc3ee066223106f42f646b.jpg?v=1788802314","url":"https:\/\/voomisupply.com\/products\/accupro-12179745-square-end-mill-1-2-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
