With a 3\/16 inch cutting diameter and 4-flute spiral geometry, this tool delivers clean square shoulders, slots, and profiling cuts in ferrous and non-ferrous materials. The 30-degree helix angle promotes efficient chip evacuation while reducing cutting forces. At 2 inches overall length with a 5\/8 inch length of cut, the 447-1875 is built for tight-tolerance work in compact setups. Micrograin carbide construction provides hardness and wear resistance suited to high-speed machining applications. Installation and use are handled by CNC machinists and manual mill operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard 3\/16 inch collets and tool holders used in vertical machining centers, CNC mills, and manual knee mills. The centercutting geometry allows plunge entry as well as conventional and climb milling passes. Left-hand flute direction combined with right-hand cut promotes chip pulling away from the finished surface, which is useful in slotting and pocket milling. The regular-length profile makes it well suited to shallow-to-mid-depth features where rigidity is a priority over extended reach.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for hardness and extended tool life\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled start hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with left-hand flute direction to pull chips away from the work surface\u003c\/li\u003e\n\u003cli\u003e3\/16 inch shank matches cutting diameter for direct collet mounting without adapter\u003c\/li\u003e\n\u003cli\u003eUncoated finish  -  suitable for re-coating or use as-ground in light to moderate duty applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for 3\/16 inch collet systems on CNC vertical machining centers and manual milling machines; belongs to OSG Series 447.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and torque the collet nut according to the tool holder manufacturer specifications before engaging the spindle. Ensure the machine spindle is fully stopped and power is isolated before changing end mills. Verify runout with a dial indicator after installation  -  excessive runout accelerates tool wear and degrades surface finish. Follow applicable shop safety practices and machine guarding requirements during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\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: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003c\/strong\u003e: Uncoated\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: 447\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.1 pounds\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: 447-1875\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51787039834418,"sku":"447-1875","price":35.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3ef032580fac0b2a129439f7e2be662.jpg?v=1789209287","url":"https:\/\/voomisupply.com\/products\/osg-447-1875-square-end-mill-3-16-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
