It features a 0.5 inch mill diameter, a 1.25 inch length of cut, and a 3 inch overall length. The cutting end carries a 0.060 inch corner radius that reduces stress concentrations at the base of a cut and extends tool life in high-demand applications. A ZrN (zirconium nitride) coating improves hardness and wear resistance, making this end mill well suited for abrasive materials. This tool is installed and operated by machinists and CNC operators in production and job shop settings.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard milling machines and CNC machining centers equipped with a 1\/2 inch tool holder or collet. The corner radius geometry makes it appropriate for finishing and semi-finishing passes where a sharp inside corner would risk tool chipping or workpiece cracking. It is commonly used on ferrous and non-ferrous metals, hardened steels, and similar materials where a ZrN coating provides a performance advantage. Single-end configuration means the tool is used from one end only.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.060 inch corner radius reduces edge chipping and stress risers at cut transitions\u003c\/li\u003e\n  \u003cli\u003eZrN coating increases surface hardness and wear resistance for extended tool life\u003c\/li\u003e\n  \u003cli\u003eSolid micrograin carbide construction provides rigidity and thermal stability\u003c\/li\u003e\n  \u003cli\u003e3-flute design balances chip evacuation and cutting edge strength\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute direction for standard CNC and manual mill setups\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows plunge entry directly into the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any milling machine or CNC machining center that accepts a 1\/2 inch shank end mill.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or tool holder to the recommended gauge line depth and torque the retention mechanism per the machine tool manufacturer specifications. Inspect the cutting edges and corner radius for chips or wear before each use.\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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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: 0.060 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 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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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 Helix\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002000 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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: 314854\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734755868978,"sku":"314854","price":111.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/564c181b598bb6286350298ab5a14e21.jpg?v=1788766625","url":"https:\/\/voomisupply.com\/products\/accupro-314854-corner-radius-end-mill-1-2-in-zrn-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
