It features a 3\/8-inch cutting diameter with a 1\/2-inch length of cut, a matching 3\/8-inch shank, and a 2-1\/2-inch overall length. Constructed from micrograin solid carbide, this double-end tool delivers consistent rigidity and edge retention at elevated cutting speeds. The 40-degree helix angle promotes efficient chip evacuation, and the uncoated finish suits applications where coating compatibility with the workpiece material or coolant is a concern. Installed by machinists and tool-and-die professionals on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for stub-length milling applications where reduced overhang and improved rigidity are priorities. The centercutting geometry allows direct plunge entry into the workpiece, enabling slotting, profiling, and pocket-milling operations without a pre-drilled hole. The right-hand cut and right-hand spiral flute configuration is standard for conventional and climb milling on vertical machining centers. It is appropriate for use on ferrous and non-ferrous materials where an uncoated micrograin carbide tool is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-inch cutting diameter with micrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two usable cutting ends, extending tool life per unit\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle with spiral flutes for effective chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eStub length type reduces deflection in tight-clearance setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard spindle rotation on vertical machining centers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for CNC machining centers and manual vertical mills accepting a 3\/8-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the spindle is fully stopped and machine power is off before changing tooling. Verify shank seating depth and runout with a dial indicator before beginning a cut. Follow shop-floor speeds and feeds charts appropriate for the workpiece material and machine horsepower when setting cutting parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\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\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 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\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 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: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 12185236\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727998091570,"sku":"12185236","price":75.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f3ff5cf03b5bd04cae9bcfcd40880b7.jpg?v=1788685783","url":"https:\/\/voomisupply.com\/products\/accupro-12185236-square-end-mill-3-8-inch-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
