Osg 300-1800 Chucking Reamer Wire Size 15 Solid Carbide

Product Description

The OSG 300-1800 is a solid carbide chucking reamer designed for precision hole finishing in general machining applications. Built to Series 300D standards, it produces a reamed diameter of 0.1800 inches (Wire Size 15) with a tight tolerance of +0.0001 to +0.0004 inches, making it suitable for close-tolerance bore work. The straight flute geometry and right-hand cutting direction suit it for use in CNC machining centers, manual mills, and drill presses. At 2.75 inches overall length with a 0.875-inch flute length, this compact reamer fits standard chucks without extension. The bright, uncoated carbide construction handles a wide range of ferrous and non-ferrous workpiece materials. Installation and operation are handled by machinists and tool-and-die professionals.

This reamer is intended for general machining environments where repeatable, accurate hole sizing is required. The straight-cylindrical shank seats directly in a collet chuck or drill chuck, keeping setup time minimal. Typical applications include finishing pre-drilled or bored holes to Wire Size 15 specification in production and job-shop settings. With 4 flutes and a solid carbide body, the tool maintains dimensional accuracy across moderate production runs on materials ranging from aluminum to mild steel.

Installation Notes

This reamer is installed and operated by machinists in machine shop environments. Secure the straight-cylindrical shank firmly in a collet or drill chuck before operation, and ensure the spindle is fully stopped before tool changes. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Follow applicable shop safety and machine guarding requirements during operation.
