Built from M7 high speed steel with an uncoated finish, it features a 0.75-inch cutting diameter and a 1.625-inch length of cut. The 4-flute, right-hand spiral configuration provides efficient chip evacuation and a smooth surface finish. With a 30-degree helix angle and regular-length geometry, this tool suits production shops and tool rooms where HSS tooling is preferred for its toughness and regrindability. Licensed machinists and CNC operators are the primary users.\u003c\/p\u003e\u003cp\u003eThis ball end mill is suited for milling ferrous and non-ferrous metals in both manual and CNC machining centers. Its 0.75-inch shank diameter matches standard collet and end mill holder tooling, and the 3.875-inch overall length keeps it rigid in typical setup configurations. Applications include profiling dies and molds, machining radii, and blending contours in general-purpose shop work. The uncoated HSS construction makes it a practical choice where regrinding is part of the tooling workflow.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for toughness and regrind capability\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral design for smooth cutting action and chip clearance\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle suited for profiling and contour passes\u003c\/li\u003e\n\u003cli\u003eBall nose geometry enables 3D surface milling and radius work\u003c\/li\u003e\n\u003cli\u003eUncoated finish compatible with standard cutting fluids and oils\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 0.75-inch shank for standard toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-end ball end mill with a 0.75-inch shank diameter, compatible with conventional end mill holders, collet chucks, and milling machine spindles accepting 3\/4-inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Set tool runout within acceptable limits using a dial indicator before commencing cuts. Do not exceed the recommended depth of cut or feed rate for HSS tooling in the workpiece material being machined.\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\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.875 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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\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\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: E202004802\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735266623794,"sku":"E202004802","price":130.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f431241e8a1df36c8eaddb14ddb0280.jpg?v=1788771220","url":"https:\/\/voomisupply.com\/products\/hertel-e202004802-ball-end-mill-0-75in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
