Built from micrograin solid carbide, it delivers rigidity and wear resistance suited to high-demand cutting environments. The 3\/4 inch diameter cutting edge runs a 1-5\/8 inch length of cut with a 45-degree helix angle, promoting efficient chip evacuation and reduced cutting forces. At 4 inches overall length with a matching 3\/4 inch shank diameter, this tool mounts directly in standard ER or end mill holders. The bright\/uncoated finish makes it a general-purpose workhorse for shops running dry or with cutting fluid. Machinists, tool-and-die makers, and CNC operators across job shops and production floors are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling on machining centers and manual knee mills. Its 2-flute geometry provides wider chip gullets, making it particularly effective in softer materials and applications where chip clearance is a priority. The right-hand cut and right-hand spiral flute direction match conventional spindle rotation on standard vertical and horizontal machining centers. The centercutting capability allows plunge entry directly into the workpiece without a pre-drilled pilot hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for extended tool life and dimensional stability\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes smooth cutting action and efficient chip flow\u003c\/li\u003e\n\u003cli\u003e2-flute design provides maximum chip clearance for softer materials and slotting operations\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without a starter hole\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with dry cutting and most cutting fluids\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000\/-0.002 inches and shank tolerance of +0.0001\/-0.0004 inches for precise fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill fitting standard 3\/4 inch end mill holders, collet chucks, and ER collet systems on CNC machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before tool changes. Seat the shank fully into the holder to the recommended grip depth before torquing the retention hardware to the tool holder specification. Inspect the shank and collet bore for contamination or damage before each setup to maintain runout tolerances.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.625 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: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand Spiral\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\/-0.002 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\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: 313439\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748052762930,"sku":"313439","price":336.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/887a3feec899c1784f735d55358c96c9_e95228b4-9aa8-4e11-81e3-93c968ba4351.jpg?v=1788888497","url":"https:\/\/voomisupply.com\/products\/accupro-313439-square-end-mill-3-4-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
