Built from M42 cobalt high-speed steel and finished with a TiN (titanium nitride) coating, it delivers increased hardness and heat resistance compared to standard HSS tooling. The 1.25-inch diameter cutter features 6 flutes configured in a right-hand cut, right-hand helix orientation, producing the characteristic chip-breaking action roughing geometry is known for. With a 6-inch length of cut and 8.5-inch overall length, this tool suits deep-pocket and long-reach milling applications. It is installed and operated by machinists and tool-and-die professionals working on CNC and manual milling equipment.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for roughing passes on ferrous metals and harder alloys where high material removal rate is the priority over surface finish. The non-centercutting design means it is intended for peripheral and side milling rather than plunge cuts. The 1.25-inch shank diameter matches the cutter diameter, making it compatible with standard ER or end mill holders sized for 1-1\/4-inch straight shanks. Typical applications include roughing pockets, slots, and profiles on milling machines in job shop, production, and maintenance machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved heat and wear resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends cutting edge life and reduces friction in the cut\u003c\/li\u003e\n  \u003cli\u003e6-flute configuration increases feed rate capability and improves surface contact on roughing passes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand helix for standard climb or conventional milling setups\u003c\/li\u003e\n  \u003cli\u003e6-inch length of cut supports deep-pocket milling and long-reach applications\u003c\/li\u003e\n  \u003cli\u003eNon-centercutting geometry — intended for side and peripheral milling, not plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1-1\/4-inch end mill holders, ER collet chucks, or Weldon shank holders on CNC machining centers and manual knee mills equipped to accept this shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and changed by qualified machinists following established shop safety procedures. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Confirm the holder bore and collet are clean and free of chips before seating the shank. Do not use this tool for plunge cutting — the non-centercutting end geometry is not designed for axial entry into solid material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\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 Helix\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: 2 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: 723-6844\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699813613874,"sku":"723-6844","price":397.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/42f34441f432ae86c3104d6aea720596.jpg?v=1788381415","url":"https:\/\/voomisupply.com\/products\/value-collection-723-6844-roughing-end-mill-1-1-4-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
