With a 7\/16-inch (0.4375-inch) cutting diameter and a 1-inch length of cut, this tool handles slotting, profiling, and pocketing applications where tight tolerances are required. The 45-degree helix angle promotes smooth chip evacuation and reduces cutting forces. Five flutes provide a higher feed rate capability compared to standard 4-flute tooling, making this end mill well suited to finishing passes and semi-finish machining in stable setups. Micrograin carbide substrate supports edge sharpness and wear resistance across a range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers, vertical mills, and toolroom applications where consistent dimensional accuracy is needed. The bright\/uncoated finish makes it a practical choice for aluminum, brass, copper, and other non-ferrous materials where coating adhesion is not a priority. Its regular length classification and single-end geometry are standard for general-purpose milling tasks in job shops, maintenance shops, and production environments. Machinists and CNC operators working with tight-tolerance features will find the micrograin carbide construction and right-hand flute direction appropriate for typical climb and conventional milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-flute geometry supports higher feed rates and improved surface finish on finish and semi-finish passes\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes efficient chip evacuation and reduces cutting force\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suited to non-ferrous and non-abrasive material applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose solid carbide square end mill for use in CNC machining centers and manual mills accepting a 7\/16-inch straight shank toolholder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank fully in a collet, end mill holder, or shrink-fit holder to the minimum recommended engagement depth before tightening. Confirm runout at the cutting edge with a dial indicator before commencing cutting operations. Always power down and lock out the spindle before changing tooling in accordance with applicable machine guarding and lockout\/tagout procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\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: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches (2.75 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\u003eChipbreaker\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: +0.000 \/ -0.002 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\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: 2500318\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755637866802,"sku":"2500318","price":76.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77280da615afbe54541328ddd3d3ea3c.jpg?v=1788957401","url":"https:\/\/voomisupply.com\/products\/accupro-2500318-square-end-mill-7-16-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
