It features a 1.25-inch cutting diameter and a 4-flute, right-hand spiral configuration ground from high speed steel. The bright, uncoated finish makes it a straightforward workhorse for general-purpose milling where specialized coatings are not required. With a 2-inch length of cut and 4.5-inch overall length, this tool fits standard vertical and horizontal milling setups. Machinists and tooling professionals install this type of end mill in manual mills and CNC machining centers alike.\u003c\/p\u003e\u003cp\u003eThis ball end mill is suited for producing radii, slots, and contoured features in shop environments handling medium-duty material removal. Its 1.25-inch shank diameter matches standard R8, CAT, or BT toolholders sized for that bore. The right-hand cutting direction is standard for conventional and climb milling operations on knee mills and machining centers. It is appropriate for job shops, tool rooms, and production environments working in steel, aluminum, and similar materials at moderate cutting speeds typical for high speed steel tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.25-inch ball nose cutting diameter for radius and contour profiling\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral geometry for balanced chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003e2-inch length of cut accommodates moderate-depth profiling passes\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides toughness in interrupted or manual-feed applications\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose milling without coating-specific speed requirements\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 1.25-inch straight shank for direct collet or end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-end ball end mill replacement for general milling applications requiring a 1.25-inch diameter, 4-flute, high speed steel tool with a 1.25-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists using an appropriate end mill holder or collet sized to the 1.25-inch shank. Ensure the spindle is fully stopped and locked before changing tooling. Torque the retention mechanism per the toolholder manufacturer specifications and verify runout with a dial indicator before commencing a cut. High speed steel tooling requires conservative speeds and feeds relative to carbide; consult published HSS cutting data 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: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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: 0.5 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 320-3785\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698089558322,"sku":"320-3785","price":239.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c123f72c005a84f7ba75b787806399b.jpg?v=1788357592","url":"https:\/\/voomisupply.com\/products\/value-collection-320-3785-ball-end-mill-1-1-4-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
