Built from submicron-grade solid carbide, it delivers the rigidity and edge retention required for interrupted cuts and high-feed roughing passes. The chipbreaker geometry along the cutting edges reduces cutting forces and helps break chips into manageable lengths, lowering the risk of chip packing in deep cavities. With a 5\/16-inch diameter, a 1-1\/8-inch length of cut, and a 3-inch overall length, this tool fits standard 5\/16-inch collets and tool holders. It is installed and used by machinists and CNC operators working in job shops, production facilities, and maintenance environments.\u003c\/p\u003e\u003cp\u003eThe 125626 is suited for roughing passes on ferrous and non-ferrous metals in vertical and horizontal machining centers as well as manual milling machines. Its bright, uncoated finish makes it a straightforward choice when coolant-based lubrication is used and when coating compatibility with specific workpiece materials is a concern. The right-hand cutting direction and right-hand spiral flutes are standard for conventional and climb milling setups. Three flutes provide a balance between chip evacuation and radial rigidity at this diameter, making the tool practical for slotting, profiling, and pocketing operations where a roughing pass precedes a finish cut.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eChipbreaker geometry reduces cutting forces and prevents chip packing\u003c\/li\u003e\n\u003cli\u003eHigh helix, right-hand spiral flutes promote efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting capable, allowing plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003eShank diameter tolerance h6 for consistent fit in precision collets and holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill compatible with standard 5\/16-inch collets, ER collet chucks, and end mill holders used on vertical machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator with the spindle fully powered down and locked out before changing tooling. Seat the shank fully into the collet or holder to the minimum insertion depth recommended by the tool holder manufacturer, and torque the retention mechanism to the holder specification. Inspect the cutting edges for chips or damage before each use. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches \/ 7.94 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eLength of Cut\u003c\/strong\u003e: 1-1\/8 inches (1.1250 inches \/ 28.57 mm)\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: 5\/16 inches (0.3125 inches \/ 7.94 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\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: +0.002 to -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 125626\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732098220338,"sku":"125626","price":129.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a00fd1d709a4843068ad7fa1e2c4e81.jpg?v=1788739166","url":"https:\/\/voomisupply.com\/products\/accupro-125626-roughing-end-mill-5-16-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
