Built from M42 cobalt high-speed steel, this tool features a TiAlN coating that extends tool life under elevated cutting temperatures. The 3\/4 inch diameter, 4-flute coarse-pitch spiral design breaks chips efficiently and reduces cutting forces during heavy passes. With a 3 inch length of cut and 5-1\/4 inch overall length, it suits deep-pocket roughing and slot milling in ferrous and difficult-to-machine materials. Right-hand cutting and right-hand flute direction are standard. Licensed machinists and CNC operators are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing passes in job shop, production machining, and toolroom environments. It performs in vertical and horizontal milling machines as well as CNC machining centers. The coarse pitch geometry is particularly effective when removing large amounts of material from steel, stainless steel, and other tough alloys in a single or multiple passes before a finish end mill is applied. The non-centercutting design means plunge cutting is not recommended; conventional or climb milling entry is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat and wear resistance in tough alloys\u003c\/li\u003e\n\u003cli\u003eTiAlN coating reduces friction and extends tool life at higher cutting speeds\u003c\/li\u003e\n\u003cli\u003eCoarse-pitch, 4-flute spiral geometry for efficient chip evacuation during heavy roughing\u003c\/li\u003e\n\u003cli\u003e3 inch length of cut supports deep-pocket and long-reach roughing applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle setups\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 3\/4 inch shank for direct collet or end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/4 inch collets, end mill holders, or milling chucks on vertical mills, horizontal mills, and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and locked out per applicable machine safety procedures. Seat the 3\/4 inch shank fully and evenly in a clean, properly sized collet or end mill holder before torquing the retention hardware. Do not use this tool for plunge cutting, as it is a non-centercutting design. Inspect the cutting edges and coating for chips or wear before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 62852819\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731872416050,"sku":"62852819","price":189.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52d6cb789c0fbe385b67bf7904e6f188.jpg?v=1788735903","url":"https:\/\/voomisupply.com\/products\/hertel-62852819-roughing-end-mill-3-4-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
