Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention that standard HSS tooling cannot match at elevated cutting speeds. The double-end design provides two usable cutting ends, extending tool life per unit. With a 7\/64 inch cutting diameter, a 21\/64 inch length of cut, and a 30-degree helix angle, it is suited for slotting, profiling, and peripheral milling in tight-tolerance work. Machinists in job shops, tool rooms, and production environments use this style of end mill for everyday steel and stainless steel operations.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for milling steel, stainless steel, cast iron, and high-temperature alloys. The 3\/16 inch shank diameter fits standard collet chucks and end mill holders on manual knee mills, CNC machining centers, and drill presses equipped for light milling. The spiral flute geometry evacuates chips efficiently in conventional and climb milling passes. The centercutting capability allows plunge entry directly into the workpiece without a pre-drilled hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for superior heat and wear resistance versus standard HSS\u003c\/li\u003e\n\u003cli\u003eDouble-end design delivers two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip evacuation and reduced cutting force\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with a wide range of cutting fluids and lubricants\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flute configuration for standard milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/16 inch collet chucks and end mill holders.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank to the full recommended collet or holder engagement depth to prevent pullout under cutting loads. Verify runout with a dial indicator before committing to a finish pass, and apply appropriate cutting fluid for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/64 inch (0.1094 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 21\/64 inch (0.3281 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/4 inches (2.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eSingle or Double End\u003c\/strong\u003e: Double\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\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VCCCDE-C-2-30H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 723-1640\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717703172402,"sku":"723-1640","price":36.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ea30971af79c9e36ef03037b3f9f6e3.jpg?v=1788544678","url":"https:\/\/voomisupply.com\/products\/value-collection-723-1640-square-end-mill-7-64-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
