It features a 1\/2-inch cutting diameter, a 5\/8-inch length of cut (0.6250 inches), and a 3-inch overall length. The 0.060-inch corner radius reduces stress concentration at the tool-workpiece junction, extending both tool life and part finish quality. A ZrN (zirconium nitride) coating improves wear resistance and lubricity at the cutting edge. With a 37-degree helix and three right-hand spiral flutes, the 314827 is center-cutting and capable of plunge entry. It is a single-end tool with a 1\/2-inch shank diameter. Intended for use by machinists and CNC operators in job shop, production, and maintenance machining environments.\u003c\/p\u003e\u003cp\u003eThis end mill suits applications requiring a radius transition between a floor and a wall in a milled pocket or slot. The ZrN coating makes it well suited for cutting aluminum, stainless steel, alloy steels, and similar materials where heat buildup and edge buildup are primary concerns. It is appropriate for use in vertical machining centers, horizontal mills, and manual knee mills where a 1\/2-inch shank toolholder is available. The regular-length geometry keeps it rigid in shallow-to-medium-depth milling passes, reducing chatter and deflection during finish cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.060-inch corner radius reduces stress risers and improves surface finish at pocket corners\u003c\/li\u003e\n\u003cli\u003eZrN coating provides wear resistance and reduces built-up edge in a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eThree right-hand spiral flutes with 37-degree helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eSingle-end, regular-length design maintains stiffness in standard-depth applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard selection for any toolholder accepting a 1\/2-inch shank end mill, including collet chucks, end mill holders, and shrink-fit holders conforming to 1\/2-inch bore specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Confirm the shank is fully seated to the minimum clamping depth recommended by the toolholder manufacturer before tightening. Do not exceed the tool runout tolerances specified for the shank diameter: +0.0001 inch \/ -0.0004 inch. Verify feed rate, spindle speed, and depth of cut parameters against the material being machined before starting the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 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: 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 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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eLength Type\u003c\/strong\u003e: Regular\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\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: 314827\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728378069298,"sku":"314827","price":104.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4cb76cf437c9ba26c7fb7f0239724cf5.jpg?v=1788690774","url":"https:\/\/voomisupply.com\/products\/accupro-314827-corner-radius-end-mill-1-2-in-3-flute-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
