It features a 0.5 inch cutting diameter, a 2 inch length of cut, and a 4 inch overall length with a 0.5 inch shank. Constructed from micrograin solid carbide and coated with a ZrN (zirconium nitride) finish, this end mill offers improved wear resistance and extended tool life in demanding cuts. The 40-degree helix angle and 3-flute spiral geometry promote efficient chip evacuation and smooth cutting action. It is centercutting, allowing direct plunge entry into workpieces without a pre-drilled hole.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling ferrous and non-ferrous materials in production and job shop environments. The long-length configuration with a 2 inch length of cut makes it appropriate for deep pocket milling, slotting, and profiling operations where standard-reach tooling falls short. It is installed and operated by machinists and CNC programmers working on vertical machining centers, manual knee mills, and similar machine tools. Right-hand cut and right-hand flute orientation is standard for conventional spindle-up milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eZrN coating provides a hard, low-friction surface for extended tool life\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes aggressive chip evacuation and reduced cutting force\u003c\/li\u003e\n\u003cli\u003e3-flute design balances chip load capacity with core strength\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge milling without pilot drilling\u003c\/li\u003e\n\u003cli\u003eLong-length classification with 2 inch LOC for deep pocket and slot applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard 1\/2 inch shank square end mills in CNC and manual milling machine tool holders with a 1\/2 inch collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank in a properly sized collet or end mill holder, torquing to the tool holder specification per the manufacturer. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates edge wear and reduces part accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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: 3\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\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 12179746\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727522038066,"sku":"12179746","price":126.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec1f6b1187f14234069e411f819526de.jpg?v=1788678859","url":"https:\/\/voomisupply.com\/products\/accupro-12179746-square-end-mill-1-2-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
