It features a 3\/16-inch cutting diameter, a 9\/32-inch length of cut, and a 3\/8-inch shank diameter with an overall length of 2-3\/4 inches. The 30-degree spiral flute geometry promotes efficient chip evacuation in a wide range of milling operations. Right-hand cut and right-hand flute configuration are standard. This tool is used by machinists and tool-and-die professionals on manual mills, CNC machining centers, and knee mills for profiling, slotting, and side-milling work in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for light profiling and slotting passes on small-scale workpieces where a compact cutting diameter is required. The double-end design extends usable tool life by providing two cutting ends per shank. The TiN coating adds surface hardness and reduces friction at the cutting edge, helping extend tool life in general-purpose shop environments. It is appropriate for use in job shops, maintenance machining, toolroom work, and production environments running smaller spindles or high-speed machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/16-inch cutting diameter with 9\/32-inch length of cut for compact slotting and profiling\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two usable cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003eTiN finish increases surface hardness and reduces edge friction for extended tool life\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle with spiral flute geometry for effective chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration for standard milling spindles\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction suitable for general-purpose ferrous and non-ferrous milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stock end mill for machine tools accepting a 3\/8-inch shank diameter, including manual knee mills, CNC vertical machining centers, and toolroom mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Secure the shank in a collet or end mill holder rated for the 3\/8-inch shank diameter and verify runout before cutting. This tool is not centercutting and should not be used for direct plunge entry into solid material. Power down and lock out the spindle before changing tooling in accordance with applicable shop safety procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 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: 9\/32 inch (0.2813 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches\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\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 Configuration\u003c\/strong\u003e: Double End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: E899921319\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752280949042,"sku":"E899921319","price":37.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82a1230546957e6d0b621ac99bcbe76d.jpg?v=1788927136","url":"https:\/\/voomisupply.com\/products\/hertel-e899921319-square-end-mill-3-16-in-4-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
