Built from M7 grade high speed steel with a TiN (titanium nitride) coating, it provides improved wear resistance and heat tolerance compared to uncoated HSS tooling. The cutter measures 11\/16 inches in diameter with a 1-5\/8 inch length of cut and a 1\/2 inch shank diameter, giving it a regular-length profile suited to a wide range of knee mill, vertical machining center, and manual lathe setups. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation during side milling, slotting, and profiling operations. This tool is installed and used by machinists and tool-and-die professionals working in job shops, maintenance departments, and production environments.\u003c\/p\u003e\u003cp\u003eThe E8031906 is intended for right-hand cut, right-hand flute applications on ferrous and non-ferrous materials where a standard square-end profile is required. Its regular length and 3-5\/8 inch overall length make it practical for setups where reach and rigidity need to be balanced. The non-centercutting geometry means it is not suited for direct plunge entry but performs well in ramping, side-milling, and peripheral cutting operations. Typical applications include profile milling, shoulder cuts, and step machining on steel, cast iron, aluminum, and similar materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction with TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e11\/16 inch cutting diameter with 1-5\/8 inch length of cut\u003c\/li\u003e\n\u003cli\u003eFour spiral flutes at a 30-degree helix angle for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation\u003c\/li\u003e\n\u003cli\u003e1\/2 inch straight shank fits standard ER collets and end mill holders\u003c\/li\u003e\n\u003cli\u003eNon-centercutting design — suited for side milling, profiling, and ramping entries\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-end square end mill compatible with 1\/2 inch end mill holders, ER32 collet chucks, and similar toolholding systems used on vertical knee mills, CNC machining centers, and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop-standard toolholding procedures. Ensure the machine spindle is fully powered down and locked before inserting or removing the end mill from the holder. Use a properly sized collet or end mill holder to achieve adequate clamping force and minimize runout. Verify tool projection and setup rigidity before initiating a cut, and confirm the programmed feed and speed values are appropriate for the workpiece material and depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/16 inches (0.6875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches (0.500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel — M7 Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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: 30 degrees\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.55 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: E8031906\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735234543922,"sku":"E8031906","price":76.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d342e0f440969cd32e8a3ddab8701883.jpg?v=1788770659","url":"https:\/\/voomisupply.com\/products\/hertel-e8031906-square-end-mill-11-16-in-4-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
