Built from M7 high speed steel with no coating applied, it delivers reliable cutting performance in conventional milling operations. The 3\/4 inch cutting diameter pairs with a 1-5\/8 inch length of cut and a 1\/2 inch shank diameter, giving machinists a rigid, controllable tool for slotting, profiling, and peripheral milling. The 42-degree helix angle promotes efficient chip evacuation and reduces cutting forces across a variety of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for job shop and production environments where HSS tooling is preferred over carbide — particularly in interrupted cuts, manual machines, or applications where tool cost and regrindability matter. The centercutting geometry allows direct plunge entry into the workpiece without a pre-drilled hole. Right-hand cut and right-hand flute configuration is standard for use in conventional vertical and horizontal milling machines and machining centers running standard spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM7 high speed steel construction for toughness in interrupted and general-purpose cuts\u003c\/li\u003e\n  \u003cli\u003e42-degree helix angle for effective chip evacuation and reduced cutting force\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e2-flute configuration provides ample chip clearance in slotting and full-width cuts\u003c\/li\u003e\n  \u003cli\u003eSpiral flute, uncoated finish — suitable for regrinding to extend tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — standard orientation for most milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in milling machines and machining centers accepting a 1\/2 inch shank diameter.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the collet or end mill holder. Verify that the shank is clean and fully seated to the proper engagement depth in the holder to prevent runout and tool pullout under load. Do not exceed the tool manufacturer recommended speeds and feeds for the specific workpiece material and cut type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.6250 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\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\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\u003eHelix Angle\u003c\/strong\u003e: 42 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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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: GG99914142\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752793538866,"sku":"GG99914142","price":86.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a2e290a5df3b421c208ad3acf4f76f6.jpg?v=1788930360","url":"https:\/\/voomisupply.com\/products\/hertel-gg99914142-square-end-mill-3-4-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
