Built from M7 high speed steel with a titanium nitride (TiN) finish, it carries a 1.125-inch cutting diameter and a 1.5-inch length of cut. The 30-degree spiral flute geometry and right-hand cut with right-hand flute direction promote efficient chip evacuation and stable tool engagement. Centercutting capability allows plunge entry directly into the workpiece. This tool is sized for use in standard milling machines, knee mills, and CNC machining centers and is typically installed by machinists and toolroom technicians.\u003c\/p\u003e\u003cp\u003eThis end mill suits a wide range of milling applications including slotting, profiling, and peripheral milling in shop and production environments. The 0.75-inch shank diameter fits standard R8, CAT, BT, and direct-mount toolholders common in vertical and horizontal milling setups. With a 3.875-inch overall length and 2-flute configuration, it is well suited for applications requiring a balance of chip clearance and core strength, particularly in softer steels, aluminum alloys, and plastics.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for toughness and wear resistance in general milling\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e30-degree helix spiral flute promotes smooth cutting action and effective chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for use in standard spindle rotation\u003c\/li\u003e\n\u003cli\u003e2-flute geometry maximizes chip clearance in softer or gummy materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement end mill for standard 0.75-inch shank toolholders used in vertical knee mills, manual milling machines, and CNC machining centers requiring a 1.125-inch diameter square end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the collet or set-screw holder is torqued according to the toolholder manufacturer specification. Inspect the cutting edges for chips or wear before use and confirm proper tool runout with a dial indicator when precision work is required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.125 inches (1-1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches (1-1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.875 inches (3-7\/8 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: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eEnd Type\u003c\/strong\u003e: Single End Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 pounds\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: E803010803\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732481704242,"sku":"E803010803","price":141.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60514857c8474e4353b3d52a97cceb29.jpg?v=1788743432","url":"https:\/\/voomisupply.com\/products\/hertel-e803010803-square-end-mill-1-1-8-in-2-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
