Manufactured from M7 high speed steel, this tool features a 1.75-inch cutting diameter and a 1.625-inch length of cut, making it well-suited for slotting, peripheral milling, and profiling in ferrous and non-ferrous materials. The 30-degree helix spiral flute geometry promotes efficient chip evacuation and helps reduce cutting forces during operation. With a 0.75-inch shank diameter and 3.875-inch overall length, this end mill fits standard milling chucks and collet systems used in manual and CNC milling machines. It runs with right-hand cut and right-hand flute direction.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for job shops, tool rooms, and maintenance machining environments where HSS tooling is preferred over carbide for interrupted cuts or applications that benefit from greater toughness. The centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled hole. With two flutes, the tool provides ample chip clearance for slotting and full-width cuts, which is especially useful in softer alloys and low-rigidity setups where recutting chips is a concern. It is installed and operated by machinists and CNC operators in production and prototype machining contexts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.75-inch mill diameter with 1.625-inch length of cut for deep slotting and peripheral passes\u003c\/li\u003e\n  \u003cli\u003eM7 high speed steel construction provides toughness for interrupted cuts and variable-material applications\u003c\/li\u003e\n  \u003cli\u003e30-degree helix spiral flute promotes efficient chip flow and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eTwo-flute configuration maximizes chip clearance in slotting and full-width milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute, uncoated — ready to run as-is or accept standard HSS coatings for extended life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard milling machine spindles and CNC machining centers accepting a 0.75-inch straight shank via collet, end mill holder, or milling chuck.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator with the machine powered off and the spindle fully stopped before tooling changes. Ensure the shank is fully seated and securely clamped in the holder to the minimum engagement depth recommended by the toolholder manufacturer. Verify spindle speed and feed rate are appropriate for the workpiece material and depth of cut before engaging the tool. Do not exceed the tool length of cut when setting axial depth of cut, as cutting beyond the flute length risks deflection and tool damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.75 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\u003eShank Diameter\u003c\/strong\u003e: 0.75 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\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\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\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.504 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: GG99914126\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728701358386,"sku":"GG99914126","price":233.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ebe1fb703966e45e1f6740eb06dcd22e.jpg?v=1788695242","url":"https:\/\/voomisupply.com\/products\/hertel-gg99914126-square-end-mill-1-3-4-inch-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
