With a 0.75-inch cutting diameter and a 4-inch length of cut, this tool handles both shallow and deep chamfering operations in a single pass. The 4-flute geometry and 30-degree right-hand helix promote efficient chip evacuation and smooth surface finishes. A bright, uncoated finish makes this tool a cost-effective choice for general-purpose and job-shop applications. Machinists and tool-and-die professionals use this type of end mill where tight edge-break tolerances are required.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual milling machines operating on steel, cast iron, aluminum, and similar materials. The centercutting capability allows direct plunge entry into the workpiece without pre-drilling. The 0.75-inch shank diameter provides a secure, rigid fit in standard ER or side-lock toolholders. Typical applications include deburring bores, chamfering mating faces, and breaking sharp edges on structural or precision components in both light manufacturing and high-mix low-volume shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for improved heat and wear resistance compared to standard high-speed steel\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand cut and right-hand flute geometry for efficient chip flow\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth cutting action and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose and re-sharpenable applications\u003c\/li\u003e\n  \u003cli\u003eFine pitch classification for precision edge work and controlled material removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank corner chamfer end mill compatible with 0.75-inch collet chucks, ER toolholders, and side-lock holders used in CNC and manual milling setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation of this end mill should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Verify that the toolholder bore and drawbar torque meet the machine manufacturer's specifications before running. Inspect the cutting edges for chips or wear before each use, and do not exceed the recommended depth of cut for the material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Type\u003c\/strong\u003e: Corner Chamfer End Mill\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.75 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\u003eLength of Cut (LOC)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003ePitch\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 6.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 pounds\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4501600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752766669106,"sku":"4501600","price":232.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4563e6f33e6007fc80e6405ba490b726_58109e78-fb6d-4480-89b3-7ce801945f4a.jpg?v=1788930182","url":"https:\/\/voomisupply.com\/products\/osg-4501600-corner-chamfer-end-mill-0-75-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
