Built from M7 high speed steel with a 30-degree helix angle and four right-hand spiral flutes, it delivers consistent chip evacuation and surface finish on ferrous and non-ferrous workpieces. The 1-inch cutting diameter pairs with a 2-inch length of cut, giving machinists meaningful depth capacity for profiling and pocketing operations. At 4.5 inches overall length with a 1-inch straight shank, it mounts securely in standard end mill holders and collet chucks without extended-reach tooling.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for manual mills and CNC machining centers in job shop, toolroom, and light production environments. It handles general-purpose profiling, contouring, and die work where a ball nose geometry is required. The uncoated M7 HSS construction makes it a practical choice for operators who resharpen tooling in-house, as HSS grinds more readily than carbide. Right-hand cutting direction is standard for conventional and climb milling on vertical and horizontal knee mills or CNC verticals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch ball nose diameter for contouring, profiling, and 3D surface milling\u003c\/li\u003e\n\u003cli\u003e2-inch length of cut provides depth capacity for pocketing and slotting\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with 30-degree helix angle for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eM7 high speed steel construction allows in-house resharpening\u003c\/li\u003e\n\u003cli\u003eUncoated finish suits general-purpose ferrous and non-ferrous applications\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 1-inch straight shank fits standard end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose single-end ball end mill with a 1-inch straight shank compatible with standard end mill holders, R8 collet chucks, and tool holders accepting a 1-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine spindle at a full stop and the control in an e-stop or locked-out state per applicable shop lockout-tagout procedures. Seat the shank fully in the holder and torque set screws or collet nuts to the holder specification. Verify runout with a dial indicator before initiating a cut. HSS end mills are sensitive to interrupted cuts and excessive feed per tooth — consult published speeds and feeds for M7 HSS at the given material and diameter before programming.\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: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\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\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\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\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: GG020064\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749158846770,"sku":"GG020064","price":162.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ccee21405a732f06d08cdf122b95c64.jpg?v=1788902772","url":"https:\/\/voomisupply.com\/products\/hertel-gg020064-ball-end-mill-1-in-4-flute-hss-uncoated","provider":"Voomi Supply","version":"1.0","type":"link"}
