Ground from M7 high speed steel and finished with a titanium nitride (TiN) coating, it offers solid wear resistance and extended tool life in ferrous and non-ferrous materials. The cutter runs a 1 inch diameter with four spiral flutes at a 30-degree helix angle, right-hand cut and right-hand flute configuration. With a 1-7\/8 inch length of cut and 3\/4 inch shank diameter, it fits standard milling chucks and collet holders without adapters. This is a non-centercutting tool and is not intended for plunge entry. Machinists and tool-and-die technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis end mill suits horizontal and vertical knee mills, CNC machining centers, and manual bridgeport-style machines running side milling, slotting, and peripheral cuts. The regular-length geometry keeps deflection low on moderate-depth passes. It is well suited for production environments where M7 HSS holds up to interrupted cuts and interrupted entries better than carbide in certain workholding setups. The 30-degree helix promotes smooth chip evacuation and reduces chatter on steel, aluminum, and similar stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for toughness in interrupted-cut applications\u003c\/li\u003e\n\u003cli\u003eTiN (titanium nitride) surface finish improves wear resistance and reduces friction\u003c\/li\u003e\n\u003cli\u003eFour-flute spiral design at 30-degree helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration — standard CNC and manual mill orientation\u003c\/li\u003e\n\u003cli\u003e3\/4 inch shank fits common collet and end mill holder sizes\u003c\/li\u003e\n\u003cli\u003eNon-centercutting geometry — requires a pre-drilled or pre-milled entry point\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in milling machines accepting a 3\/4 inch straight shank, including ER collet systems, Weldon-style end mill holders, and hydraulic chucks sized for 3\/4 inch tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and the machine in a locked-out, tagged-out state per OSHA lockout\/tagout procedures. Seat the shank fully in the holder and torque the drawbar or set screw to the holder manufacturer specification. Verify runout with a dial indicator before initiating a cut. Because this tool is non-centercutting, do not plunge directly into solid material — use a ramping or pre-drilled entry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/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\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 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\u003eCentercutting\u003c\/strong\u003e: No\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: 0.57 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: E8031919\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728217080114,"sku":"E8031919","price":102.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60ae8305460a840f3d5804e74e320274.jpg?v=1788689714","url":"https:\/\/voomisupply.com\/products\/hertel-e8031919-square-end-mill-1-in-4-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
