Built from M42 cobalt high-speed steel with a TiN coating, it delivers the heat and wear resistance needed for interrupted cuts and difficult-to-machine materials. The 3\/4 inch cutting diameter and 4-flute geometry produce the serrated chip-breaking action typical of roughing profiles, reducing cutting forces and extending tool life compared to standard finishing end mills. Right-hand cutting and right-hand flute direction are standard. This tool is intended for use in machining centers, knee mills, and manual or CNC vertical mills.\u003c\/p\u003e\u003cp\u003eThis roughing end mill suits applications in job shops, maintenance machining, and production environments where roughing passes precede finish milling. The 3 inch length of cut accommodates deeper axial engagements on steel, stainless steel, cast iron, and high-temperature alloys. The 3\/4 inch shank diameter fits standard ER collets, end mill holders, and Weldon-style side-lock holders. It is not center-cutting, so it requires a pre-drilled or pre-bored entry point and is not intended for plunge operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated heat resistance in tough materials\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e4-flute roughing profile breaks chips aggressively, lowering cutting forces\u003c\/li\u003e\n\u003cli\u003e3 inch length of cut supports deep roughing passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix for standard spindle direction\u003c\/li\u003e\n\u003cli\u003eNot center-cutting — requires pre-drilled entry; not suitable for plunge milling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit roughing end mill for standard 3\/4 inch end mill holders, ER collet chucks, and Weldon-style side-lock holders used in vertical milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tool-and-die personnel. Secure the shank fully within the holder to the recommended gauge-line depth and torque the set screw or collet nut per the toolholder manufacturer specifications. Verify spindle runout with a dial indicator before production cuts. Always power down and lock out the machine spindle before changing tooling.\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 HSS)\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: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5.25 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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eCenter Cutting\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\u003eWeight\u003c\/strong\u003e: 0.02 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: 724-3194\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721121431858,"sku":"724-3194","price":109.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6831273c2bac97ba0373616c3822019b.jpg?v=1788573856","url":"https:\/\/voomisupply.com\/products\/value-collection-724-3194-roughing-end-mill-3-4-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
