It features a chipbreaker geometry along three flutes that breaks chips into manageable segments, reducing heat buildup and cutting forces during heavy roughing passes. The 5\/8-inch mill diameter pairs with a matched 5\/8-inch straight cylindrical shank for secure toolholder engagement. A 0.03-inch corner radius adds edge strength at the cutting periphery. Built from submicron carbide grade, this tool is intended for use by machinists and toolroom professionals running CNC or manual milling equipment.\u003c\/p\u003e\u003cp\u003eThis roughing end mill suits high-volume stock removal on a range of workpiece materials where chip control is a priority. The 2.5-inch length of cut accommodates moderate depth applications in vertical and horizontal milling setups. Right-hand cutting and right-hand spiral flute direction with a high helix style make it appropriate for climb or conventional milling on ferrous and non-ferrous materials. The bright, uncoated finish is suitable for applications where coating compatibility with the workpiece or cutting fluid is a concern. Single-end configuration means the tool is replaced rather than reversed at end of life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eChipbreaker geometry on all three flutes for controlled chip segmentation during roughing cuts\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide construction for wear resistance and edge integrity\u003c\/li\u003e\n\u003cli\u003e0.03-inch corner radius strengthens the cutting edge and reduces corner chipping\u003c\/li\u003e\n\u003cli\u003eHigh helix, right-hand spiral flute direction for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for dry or wet cutting environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement roughing end mill for use in standard 5\/8-inch bore milling chucks, collet holders, and end mill holders with straight cylindrical shank retention.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with milling toolholder procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the holder to the recommended engagement depth and torque the retention fastener per the toolholder manufacturer specifications. Inspect the corner radius and cutting edges for chips or wear before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (15.90 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0012 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0020 to -0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 125997\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755690656050,"sku":"125997","price":449.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f140cb00b46cf610a755e3d28f93ed78_cb0192e2-3298-4f5d-9eb9-99b681943214.jpg?v=1788958176","url":"https:\/\/voomisupply.com\/products\/accupro-125997-roughing-end-mill-3-flute-5-8-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
