With a 1\/2 inch cutting diameter and 1-1\/2 inch length of cut, it handles slotting, profiling, and peripheral milling in a single-end configuration. The 3-flute geometry with a 37-degree right-hand spiral helix balances chip evacuation and cutting efficiency in a range of ferrous and non-ferrous materials. Micrograin carbide construction provides edge retention and resistance to chipping under demanding cutting conditions. The bright uncoated finish suits general-purpose machining where coating is not required or preferred.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard CNC machining centers, vertical mills, and manual knee mills equipped with an R8, CAT, BT, or collet-style toolholder accepting a 1\/2 inch shank. It is suited for production shops, tool rooms, and job shops running steel, aluminum, cast iron, and similar materials where a 3-flute solid carbide tool is the specified choice. The 4 inch overall length accommodates standard reach requirements without excessive overhang.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-flute right-hand spiral design with 37-degree helix angle for balanced chip flow\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for superior hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable for plunge entry and ramp milling\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of base materials\u003c\/li\u003e\n\u003cli\u003e1\/2 inch shank with tight diameter tolerance for secure toolholder fit\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 4 inch overall length for standard-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for machining setups requiring a 1\/2 inch shank, 3-flute solid carbide square end mill with a 1-1\/2 inch length of cut.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC setup technician using a collet, end mill holder, or set-screw toolholder rated for the 1\/2 inch shank diameter. Ensure the machine spindle is fully stopped and locked before inserting or removing tooling. Apply the appropriate insertion depth per toolholder manufacturer guidelines to maximize rigidity and minimize runout. Verify shank clamping torque per toolholder specifications before commencing cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 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: 37 degrees\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\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\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.005 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\u003ePackage Weight\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: 314863\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51735377314098,"sku":"314863","price":142.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cefce5efb7c3d91447fe6143a2831677_137282c0-50a2-49d1-ae4a-7df4603211b7.jpg?v=1788772169","url":"https:\/\/voomisupply.com\/products\/accupro-314863-square-end-mill-1-2in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
