Built from micrograin solid carbide and finished with an AlTiN (aluminum titanium nitride) coating, this tool delivers extended tool life and thermal resistance in demanding cutting environments. The 0.02-inch corner radius reduces edge chipping and stress concentration at the cutting corner. With a 1\/2-inch diameter, 1-5\/8-inch length of cut, and 4-inch overall length, it fits standard 1\/2-inch tool holders used across vertical and horizontal machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finish and semi-finish milling operations in aerospace, die and mold, and general precision machining applications. The single-end, centercutting design allows for plunge entries and full slot milling. A 37-degree helix angle promotes efficient chip evacuation and smooth cutting action. The variable index flute spacing helps suppress chatter and vibration during high-speed passes. Machinists and CNC operators in job shops and production environments will find this tool well matched to tight-tolerance profiling and pocket milling work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating extends tool life in high-heat, dry cutting conditions\u003c\/li\u003e\n  \u003cli\u003e7-flute geometry increases feed rates and improves finish quality\u003c\/li\u003e\n  \u003cli\u003e0.02-inch corner radius reduces corner chipping and extends edge life\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces harmonic chatter\u003c\/li\u003e\n  \u003cli\u003eCentercutting single-end design supports plunge milling and slotting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/2-inch diameter end mill holders, collet chucks, and shrink-fit tooling systems on CNC vertical and horizontal machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. Ensure the spindle is fully stopped and locked before loading or removing any cutting tool. Verify that the shank is clean and free of chips or burrs before seating in the holder, and torque the retention mechanism to the tool holder specification. Confirm runout with a dial indicator after setup to protect both the tool and the workpiece surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (0.3750 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.00150 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\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\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: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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\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: 12178712\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728249291058,"sku":"12178712","price":146.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec06be6067cdc964caafb35003910387.jpg?v=1788690070","url":"https:\/\/voomisupply.com\/products\/accupro-12178712-corner-radius-end-mill-1-2-in-7-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
