Built from M42 cobalt high-speed steel, this double-end tool delivers extended tool life in harder workpiece materials compared to standard HSS tooling. It carries a TiCN (Titanium CarboNitride) coating to reduce friction and improve wear resistance at the cutting edge. The 30-degree spiral flute geometry promotes efficient chip evacuation and smooth cutting action. At 0.25 inches in diameter with a 0.5-inch length of cut, this mill is suited for slot milling, profiling, and plunge cuts where a centercutting geometry is required.\u003c\/p\u003e\n\u003cp\u003eThis end mill is a general-purpose tool for use in manual mills, CNC machining centers, and knee mills running ferrous and non-ferrous materials. The 0.375-inch shank diameter allows it to seat in standard ER or straight-shank collet toolholders. The double-end design provides two usable cutting ends, which extends service intervals on high-run production jobs. It is commonly applied in job shops, maintenance machining, and tool rooms handling stainless steel, alloy steel, cast iron, and similar materials. The right-hand cut and right-hand flute orientation are compatible with standard spindle rotation on conventional milling machines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for increased hardness and heat resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle supports efficient chip flow in slot and profile milling\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute for standard CNC and manual mill compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank cobalt square end mill compatible with 0.375-inch collet chucks and straight-shank toolholders used on conventional knee mills and CNC vertical machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Power down and lock out the machine spindle before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention nut to the toolholder specification before running. Inspect the cutting edges for chipping before each use, especially after cutting hardened or abrasive materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.5 inches to 0.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 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: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003c\/strong\u003e: TiCN\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\u003eDouble End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: E7050016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51751696433458,"sku":"E7050016","price":47.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de40b2bf0ffb798a86636cf310971a30.jpg?v=1788924115","url":"https:\/\/voomisupply.com\/products\/hertel-e7050016-square-end-mill-0-25in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
