Manufactured from M42 cobalt high-speed steel, this tool handles tough materials where standard HSS tooling struggles. The 4-flute configuration with a right-hand cutting and right-hand flute direction provides efficient chip evacuation while maintaining rigidity. With a 3\/4 inch diameter and a 4.125 inch length of cut, the 723-5776 suits deep-pocket and slotting operations where extended reach into the workpiece is required. The bright, uncoated finish is standard for cobalt-grade roughers used across general-purpose machining environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in manual knee mills and CNC machining centers where roughing passes precede finishing operations. The 3\/4 inch shank diameter matches the cutter diameter, making it compatible with standard ER collet chucks, end mill holders, and weldon-style tool holders commonly found in job shops and maintenance machining environments. Non-centercutting geometry means this tool is not intended for plunge cuts; it is designed for peripheral and slotting entry strategies. It is appropriate for cutting steel, stainless steel, cast iron, and similar ferrous materials at appropriate surface speeds for cobalt tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003e4-flute single-end design optimized for roughing passes and high material removal rates\u003c\/li\u003e\n\u003cli\u003e3\/4 inch cutter and shank diameter for compatibility with standard tool holders\u003c\/li\u003e\n\u003cli\u003e4.125 inch length of cut for deep-pocket milling applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration — standard for conventional and climb milling\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish — ready for use with or without cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use roughing end mill for standard 3\/4 inch end mill holders, ER collet systems, and Weldon shank tool holders used in vertical milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed by a qualified machinist with the spindle at a complete stop and the machine in a locked-out, de-energized state per applicable lockout\/tagout procedures. Secure the shank fully within the tool holder to the minimum insertion depth recommended by the holder manufacturer — insufficient engagement can cause tool pull-out under cutting loads. Because this end mill is not centercutting, do not program plunge moves directly into solid material; use a ramping or helical entry strategy. Verify runout with a dial indicator after mounting before beginning any cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 723-5776\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694802927922,"sku":"723-5776","price":148.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8929a9b3216eedf7c9977b7e52283f2.jpg?v=1788328553","url":"https:\/\/voomisupply.com\/products\/value-collection-723-5776-roughing-end-mill-3-4-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
