Built on the HS Series platform, it features a 3\/4 inch (0.7500 inch decimal) cutting diameter, a 1 inch length of cut, and a 5-flute spiral configuration with a 38-degree helix angle. The AlTiCrN coating improves heat resistance and wear life at elevated cutting temperatures, making this tool well suited for hardened steels, stainless alloys, and high-temp materials. It is a single-end, center-cutting tool with right-hand flute direction and cut, and is used by machinists and toolroom professionals in CNC and manual milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for use in vertical machining centers, CNC knee mills, and general milling setups requiring a 3\/4 inch diameter tool. The extended reach geometry, with a 2.5 inch reach length, suits deeper cavity work where standard-reach tools cannot access. The variable index design reduces harmonic chatter during high-feed passes. Micrograin carbide substrate provides the rigidity and edge retention needed for high-speed finishing and semi-finishing passes on ferrous and non-ferrous workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4 inch cutting diameter with 1 inch length of cut for versatile milling depth\u003c\/li\u003e\n\u003cli\u003e5-flute spiral design with 38-degree helix angle for improved chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003eAlTiCrN coating for extended tool life in high-heat, high-hardness materials\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces chatter and vibration during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eExtended reach of 2.5 inches enables access to deeper cavities\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for CNC machining centers and manual mills accepting a 3\/4 inch straight shank end mill in an ER or set-screw style toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with rotating cutting tool setups. Ensure the spindle is fully stopped and the machine is powered off before changing tooling. Seat the shank fully into the toolholder and torque the collet nut or set screw per the toolholder manufacturer specifications. Verify tool runout with a dial indicator before beginning the cut to prevent premature edge wear or tool breakage.\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\u003eMill Diameter (mm)\u003c\/strong\u003e: 19.05 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (mm)\u003c\/strong\u003e: 25.40 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6 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\u003eReach Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 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: AlTiCrN\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\u003eEnd Type\u003c\/strong\u003e: Single End\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: Yes\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\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: 312333\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755179147570,"sku":"312333","price":380.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2d355c2a46c315d50a85f5368219102.jpg?v=1788951883","url":"https:\/\/voomisupply.com\/products\/accupro-312333-square-end-mill-3-4-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
