Part of the OSG Series 454, it features a 3\/16 inch (0.1875 inch) cutting diameter and a 4-flute spiral design with a 30-degree helix angle. The right-hand cut and right-hand flute geometry promote efficient chip evacuation and stable tool engagement. With an overall length of 2 inches and a length of cut of 0.625 inches, this end mill suits finish milling, slotting, and contouring work in CNC machining centers and manual mills. It is centercutting and carries a bright, uncoated finish on a micrograin carbide substrate.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in job shops, production machining environments, and tool rooms where tight tolerances and consistent surface finish are required. The 3\/16 inch shank diameter matches the cutting diameter, making it compatible with standard collet systems. The regular length designation and compact 2 inch OAL make it well-suited for applications where tool rigidity is a priority and extended reach is not required. Machinists and CNC operators working in aerospace, mold and die, and general metalworking applications will find this geometry appropriate for moderate-depth slotting and profile milling passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 30-degree helix angle for efficient chip flow and stable cutting\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry directly into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with right-hand flute direction for use in standard CNC spindle configurations\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for applications where coated tooling is not required\u003c\/li\u003e\n\u003cli\u003eRegular length profile at 2 inches OAL promotes tool stiffness and reduces deflection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in standard 3\/16 inch collet chucks and end mill holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator familiar with proper tool-holding procedures. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended engagement depth before tightening. Verify runout with a dial indicator after installation, as excessive runout will reduce tool life and surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 454\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 454-1875\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51741339910450,"sku":"454-1875","price":36.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/699160bd2338921732234d2718616229.jpg?v=1788830876","url":"https:\/\/voomisupply.com\/products\/osg-454-1875-square-end-mill-3-16-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
