Built from micrograin solid carbide, this stub-length tool offers a 3\/8 inch cutting diameter and a 1\/2 inch length of cut, making it well-suited for shallow slotting, side milling, and profiling cuts. The 60-degree helix angle promotes aggressive chip evacuation and reduces cutting forces, which is especially valuable in harder workpiece materials. With three flutes and a right-hand cutting and flute direction, this end mill is a standard choice for CNC machinists and manual mill operators working in production and toolroom environments.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers, knee mills, and similar milling equipment. The stub length design provides added rigidity, reducing deflection during cuts. The bright\/uncoated finish makes it suitable for a range of ferrous and non-ferrous materials where coating compatibility or regrinding is a consideration. It is a single-end tool with centercutting capability, allowing plunge entry into workpieces. Machinists performing die work, fixture fabrication, or general-purpose contouring will find this tool appropriate for those tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003e60-degree helix angle promotes efficient chip evacuation and reduced cutting force\u003c\/li\u003e\n\u003cli\u003eThree-flute geometry balances chip clearance with surface finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into material\u003c\/li\u003e\n\u003cli\u003eStub length configuration increases rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for regrinding and broad material compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for 3\/8 inch collet or end mill holder setups on CNC machining centers and manual milling machines requiring a stub-length, three-flute square end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle and collet or end mill holder are clean and free of debris before seating the shank. Confirm runout with a dial indicator after tooling is secured, as shank diameter tolerance is specified at +0.0001 to -0.0004 inches. Always follow machine tool manufacturer guidelines for speed and feed recommendations based on workpiece material, and verify the tool is fully retracted and the spindle is stopped before making any adjustments.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inches (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 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: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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\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\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: 2500247\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727781986610,"sku":"2500247","price":65.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fdfaadad6bc1244cdc5523c71d0b5d0e.jpg?v=1788682289","url":"https:\/\/voomisupply.com\/products\/accupro-2500247-square-end-mill-3-8-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
