It features a 0.5 inch cutting diameter, a 0.625 inch length of cut, and a 0.06 inch corner radius that reduces stress concentrations and improves surface finish at part edges. The tool is coated with ZrN (zirconium nitride) for improved wear resistance and is centercutting, allowing plunge entry into the workpiece. With a 30-degree helix angle and three flutes, it balances chip evacuation with cutting performance. It is installed and operated by machinists and CNC programmers working in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling ferrous and non-ferrous materials where a radiused corner is required to reduce stress risers or meet part print specifications. The stub length configuration — with a 2.5 inch overall length and 0.5 inch shank diameter — provides rigidity for applications where deflection control is critical. The right-hand cutting and right-hand flute direction are standard for conventional CNC mill setups. The coarse pitch classification and ZrN coating make it a practical choice for general-purpose profiling and slot milling at moderate to high feed rates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.06 inch corner radius reduces edge stress and improves part surface finish\u003c\/li\u003e\n\u003cli\u003eZrN coating provides wear resistance and extends tool life in metalcutting\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth cutting action and chip flow\u003c\/li\u003e\n\u003cli\u003eStub length with 2.5 inch OAL maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC mill spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide end mill for use in standard CNC machining centers and manual mills with a 0.5 inch collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup personnel. The shank must be fully seated and properly torqued in the tool holder before spindle operation. Confirm spindle speed and feed rate parameters are set per the shop's tooling data for the workpiece material before cutting. Inspect the cutting edges for chips or coating damage prior to use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5 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: 0.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 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: 12179644\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749234802994,"sku":"12179644","price":124.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/18a69b9a8af07bc6a82b3a0d520122c9.jpg?v=1788903440","url":"https:\/\/voomisupply.com\/products\/accupro-12179644-corner-radius-end-mill-0-5-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
