The OSG 300-2280 is a solid carbide chucking reamer designed for precision hole finishing in general machining applications. It cuts in the right-hand direction with a straight flute geometry, producing accurate, smooth bores in a wide range of materials. The reamer measures 0.2280 inches in diameter with a tight tolerance of +0.0001 to +0.0004 inches, making it suitable for close-tolerance work where hole size consistency is critical. Overall length is 3.0 inches with a 1-inch flute length. The bright, uncoated finish is standard for this carbide grade and works well across common ferrous and non-ferrous materials.
This chucking reamer is intended for use in drill presses, CNC machining centers, lathes, and manual milling machines where a straight-shank tool is held in a chuck or collet. The 0.2280-inch diameter corresponds to wire gauge size No. 1, making it a practical choice for reaming holes to specific pin, dowel, or clearance fits in production and maintenance machining environments. It is suited for machinists, tool and die makers, and maintenance technicians working with metal components requiring reamed bores.
Designed as an OEM-style solid carbide chucking reamer for general machining applications requiring a 0.2280-inch finished bore diameter with a straight-shank, straight-flute configuration.
Installation and use should be performed by qualified machinists familiar with proper reaming technique. Secure the straight-cylindrical shank in a precision chuck or collet before operation and ensure the machine spindle is properly aligned with the pre-drilled pilot hole to prevent tool deflection or breakage. Carbide tooling is brittle — avoid interrupted cuts, side loading, or hand-feeding with excessive pressure. Follow standard shop safety practices and machine guarding requirements during use.
