Built from micrograin carbide stock and coated with AlTiCrN (aluminum titanium chromium nitride), this tool handles elevated cutting temperatures and abrasive workpiece materials with extended tool life. It runs a 4-flute, single-end configuration with a 38-degree helix angle and variable index spacing, which reduces harmonic chatter during cuts. The 3\/4 inch cutting diameter and 1-5\/8 inch length of cut make it well suited for slotting, profiling, and peripheral milling passes at moderate-to-aggressive depths.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where rigidity and runout control are maintained. It is appropriate for cutting ferrous alloys, hardened steels, stainless steels, and other tough materials where standard TiN or uncoated carbide tools fall short. The right-hand cutting direction and right-hand flute spiral make it a standard spindle-forward tool for most vertical and horizontal machining setups. Machinists and toolroom technicians in job shops, production facilities, and maintenance operations are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiCrN coating provides high heat resistance and extended wear life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eMicrograin carbide substrate delivers superior rigidity and edge integrity compared to standard carbide grades\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces chatter and vibration during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eSingle-end geometry; 3\/4 inch shank diameter matches the cutting diameter for direct collet or end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill compatible with standard 3\/4 inch end mill holders, collet chucks, and shrink-fit tooling systems used in CNC and manual milling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Secure the 3\/4 inch shank in a properly sized end mill holder or collet and torque to the toolholder manufacturer's specification — do not rely on feel alone. Verify runout with a dial indicator before initiating cuts. Ensure the spindle is fully stopped and the machine is in a safe state before changing or inspecting tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (41.23 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003c\/strong\u003e: AlTiCrN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 310451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729489461554,"sku":"310451","price":287.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c45609378aac8aa3cf4ea7493ecda1f.jpg?v=1788705215","url":"https:\/\/voomisupply.com\/products\/accupro-310451-square-end-mill-3-4in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
