Built from M42 cobalt steel, this single-end stub-length tool features a 3\/16 inch cutting diameter, a 9\/32 inch length of cut, and a 30-degree right-hand spiral helix. The bright\/uncoated finish keeps tool preparation straightforward. With three flutes and a right-hand cutting direction, it is suited for slotting, profiling, and peripheral milling in ferrous and harder workpiece materials. Machinists and tool-and-die professionals working on manual mills or CNC machining centers will recognize this as a standard fractional-inch stub end mill.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in metalworking applications where a compact stub-length profile provides added rigidity in tight setups or shallow-depth work. The 1\/4 inch shank diameter fits standard ER collets, end mill holders, and Weldon-style holders common on knee mills and VMCs. The cobalt M42 substrate makes this tool a practical choice for cutting alloy steels, stainless steels, cast iron, and similar materials where carbide is not required. It is a single-end tool, so once the cutting end is worn, the tool is replaced rather than reversed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch cutting diameter with 9\/32 inch length of cut in a rigid stub-length body\u003c\/li\u003e\n  \u003cli\u003e3 flutes with right-hand spiral at 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shank diameter fits standard collet and end mill holder tooling\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish, Series VCCC-C-3, fractional-inch sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard fractional-inch stub-length square end mill compatible with any machine spindle tooling that accepts a 1\/4 inch shank, including ER collet chucks, end mill holders, and Weldon-style holders used on manual knee mills and CNC vertical machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Torque the collet nut or set screw according to the toolholder manufacturer specifications, not a generic value. Verify runout at the cutting diameter before beginning the operation, as excessive runout accelerates wear and reduces surface finish quality on cobalt tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/32 inch (0.2813 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/32 inches (1.3437 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: VCCC-C-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0167 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 723-3658\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51705259229490,"sku":"723-3658","price":27.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56c8e04876db4eead29457b2d2ee957a.jpg?v=1788427827","url":"https:\/\/voomisupply.com\/products\/value-collection-723-3658-square-end-mill-3-16-in-3-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
