Built from micrograin solid carbide and coated with nACRo for heat and wear resistance, this single-end tool features a 0.02 inch corner radius and a right-hand cutting direction with variable index geometry. It handles a 1\/2 inch mill diameter with a 1-5\/8 inch length of cut and a 4 inch overall length. The centercutting design allows plunge entry, making it a versatile option for profiling, slotting, and finishing passes. Machinists and CNC operators in job shops and production environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling operations on hardened steels, stainless alloys, high-temp alloys, and other difficult-to-machine materials where a standard end mill underperforms. The nACRo coating provides elevated oxidation resistance at high cutting temperatures, extending tool life in dry or minimum-quantity lubrication (MQL) setups. The 7-flute configuration and variable index spacing reduce harmonic chatter, improving surface finish on finishing passes. A 1\/2 inch shank diameter fits standard ER collet chucks, hydraulic chucks, and shrink-fit toolholders commonly found in machining centers and VMCs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-flute variable-index design reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003enACRo coating for high oxidation resistance and extended tool life in dry or MQL cutting\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e0.02 inch corner radius reduces stress concentration and improves edge strength at pocket corners\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables plunge milling entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute direction with right-hand cutting for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling option for 1\/2 inch shank toolholders including ER collet chucks, hydraulic chucks, and shrink-fit holders used in vertical machining centers and CNC milling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer is disabled before inserting or removing the end mill from any toolholder. Use a calibrated torque wrench when tightening collet nuts to the toolholder manufacturer specification. Verify runout with a dial indicator after seating the tool to avoid premature edge wear or tool failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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\u003eCorner Radius\u003c\/strong\u003e: 0.02 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.0015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002500 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\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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\u003eWeight\u003c\/strong\u003e: 0.41 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.13 x 0.75 x 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 12180843\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733194244402,"sku":"12180843","price":166.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a85a07ca86c2a8c8a9d14e58c46e47b0.jpg?v=1788752609","url":"https:\/\/voomisupply.com\/products\/accupro-12180843-corner-radius-end-mill-1-2-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
