The cutter measures 7\/8 inch (0.875 inch) in diameter with a 1-7\/8 inch length of cut and a 3\/4 inch shank diameter, giving it a regular-length profile suited to a wide range of vertical and horizontal milling applications. The 30-degree spiral flute geometry promotes efficient chip evacuation, while the uncoated HSS construction allows for easy resharpening in the field. This tool is installed by machinists and tool-and-die professionals working on manual knee mills, CNC machining centers, and bridgeport-style equipment.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling operations in job shops, maintenance environments, and production settings. The centercutting design allows for plunge entry into the workpiece without a pre-drilled pilot hole, adding versatility to standard milling routines. Right-hand cut and right-hand flute orientation match the standard spindle direction of most milling machines. The regular length-of-cut range of 1.5 to 2.0 inches fits common workholding setups without excessive overhang.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8 inch cutting diameter with 1-7\/8 inch length of cut for medium-depth milling passes\u003c\/li\u003e\n  \u003cli\u003eM7 high speed steel construction — resharpenable and suitable for a broad range of work materials\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle spiral flute promotes smooth chip flow and reduced cutting pressure\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — compatible with standard milling spindle rotation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish simplifies resharpening on standard tool grinding equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill for standard milling machine spindles accepting a 3\/4 inch straight shank.

Seat the shank fully into the holder and torque the set screw or collet nut to the holder manufacturer specification before starting the spindle. Inspect the cutting edges for chips or wear before each use — do not run a damaged end mill. Proper speeds and feeds for M7 HSS should be calculated based on workpiece material and depth of cut to avoid work hardening or premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/8 inch (0.875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-7\/8 inch (1.875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.750 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/8 inch\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\u003eCoating\u003c\/strong\u003e: Uncoated\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.52 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: E1043901\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747533455666,"sku":"E1043901","price":109.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e12d69898b4dd63322b366a8cf9f42a9.jpg?v=1788882061","url":"https:\/\/voomisupply.com\/products\/hertel-e1043901-square-end-mill-7-8-in-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
