Built from M42 cobalt steel, this double-end mill features a 1\/8 inch cutting diameter, a 3\/8 inch length of cut, and a 4-flute spiral geometry with a 30-degree right-hand helix. The bright\/uncoated finish is suited for applications where coating adhesion or thermal conductivity is a consideration. With a 3\/8 inch shank diameter and an overall length of 3-1\/16 inches, this tool fits standard collet chucks used by machinists and toolroom operators working on close-tolerance features.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials where cobalt tooling provides a performance advantage over standard M2 HSS. The regular-length classification and compact cutting diameter make it well suited for mold work, die work, and small-part machining on manual knee mills, CNC machining centers, and bench-top mills. The double-end configuration allows the operator to index to the second cutting end once the first end reaches the end of its useful life, extending tool life per unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved heat resistance compared to standard HSS\u003c\/li\u003e\n\u003cli\u003eDouble-end design extends usable tool life per unit\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 30-degree right-hand helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with a wide range of materials and cutting fluids\u003c\/li\u003e\n\u003cli\u003eRegular length classification for rigidity in tight-tolerance milling applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8 inch shank square end mill compatible with collet chucks, end mill holders, and tool-holding systems that accept a 3\/8 inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine spindle fully de-energized and the machine in a locked-out state per applicable shop safety procedures. Ensure the shank is fully seated and clamped in the holder to the manufacturer-recommended engagement depth before starting the spindle. Inspect the cutting edges prior to use; cobalt tooling with visible chipping or wear should not be returned to service. This tool is not center-cutting and should not be used for direct plunge operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/16 inches (3.0625 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: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 27700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710177444146,"sku":"27700","price":34.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36acd006d5e1a7e4aa57bcf57441c146.jpg?v=1788463929","url":"https:\/\/voomisupply.com\/products\/value-collection-27700-square-end-mill-1-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
