Ground from M7 high speed steel, this tool handles slotting, profiling, and peripheral milling on ferrous and non-ferrous materials. It features a 1 inch cutting diameter, a 3 inch length of cut, and a 30-degree right-hand spiral helix across 6 flutes. The bright, uncoated finish is standard for M7 HSS tooling. It is center-cutting, allowing plunge entry. Machinists and tool-and-die professionals are the primary users of this tool in manual mills and CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing and semi-finishing passes in shop environments where high speed steel tooling is preferred over carbide. The 6-flute geometry provides a higher number of cutting edges, which improves surface finish on finishing passes and supports higher feed rates in light cuts. The regular-length designation and 1 inch shank diameter make it a direct fit for standard milling chucks, collets, and end mill holders used in knee mills and vertical machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch cutting diameter with matching 1 inch shank diameter for secure toolholder engagement\u003c\/li\u003e\n\u003cli\u003e3 inch length of cut handles deep slots and pockets without extension tooling\u003c\/li\u003e\n\u003cli\u003e6 flutes for improved surface finish and higher feed-rate capability on finishing passes\u003c\/li\u003e\n\u003cli\u003eM7 high speed steel construction provides good wear resistance and toughness\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design permits plunge milling and ramping operations\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix reduces chatter and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — compatible with cutting fluids and oils standard in HSS tooling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank square end mill for use in any milling machine equipped with a 1 inch end mill holder, collet chuck, or Weldon-style holder accepting a 1 inch shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom professional. Ensure the machine spindle is fully stopped and locked before changing tooling. Seat the shank fully into the holder and verify set-screw or collet torque per the toolholder manufacturer specification. Confirm runout at the cutting diameter with a dial indicator before taking the first cut.\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: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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\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: GG042980\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747287499058,"sku":"GG042980","price":179.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/437b4775a6ca6e4c92691c8cdb5f5bc0.jpg?v=1788878685","url":"https:\/\/voomisupply.com\/products\/hertel-gg042980-square-end-mill-1-in-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
