Built from M7 high speed steel, it features a 1\/4 inch cutting diameter, a 3\/8 inch length of cut, and a 4-flute spiral configuration with a 30-degree helix angle and right-hand cut and flute direction. The uncoated finish suits applications where re-sharpening is common. Machinists and tool-and-die professionals install this end mill in vertical and horizontal milling machines and CNC machining centers for slotting, profiling, and peripheral milling on ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for light to medium material removal on steel, cast iron, aluminum, and similar workpiece materials. The double-end design extends tool life by providing two usable cutting ends. With a 3\/8 inch shank diameter and a 2-7\/8 inch overall length, it fits standard collet and end mill holders commonly found in job shops and production environments. The 30-degree helix promotes chip evacuation and reduces cutting forces during conventional milling passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM7 high speed steel construction for durability and resharpening capability\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool, extending service life\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral configuration with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard milling setups\u003c\/li\u003e\n  \u003cli\u003eUncoated finish compatible with common cutting fluids and regrinding services\u003c\/li\u003e\n  \u003cli\u003eNon-centercutting geometry suited for peripheral and slot milling rather than plunge cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for milling machines and machining centers accepting a 3\/8 inch shank end mill holder or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or end mill holder to the minimum engagement depth recommended by the holder manufacturer. Verify runout with a dial indicator before beginning the cut, as excessive runout accelerates tool wear and reduces surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/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\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double End, Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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: GG99914183\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729372053810,"sku":"GG99914183","price":30.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1dfc9423cdfc304d6796b4c55a5b74e3.jpg?v=1788703737","url":"https:\/\/voomisupply.com\/products\/hertel-gg99914183-square-end-mill-1-4-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
