Osg 300-1719 Chucking Reamer 11/64 in Solid Carbide

Product Description

The OSG 300-1719 is a solid carbide chucking reamer designed for precision hole finishing in general machining applications. With a reamer diameter of 0.1719 inches (11/64 inches) and a tight tolerance of +0.0001 to +0.0004 inches, this tool produces accurately sized, smooth bores in a single pass. The straight flute geometry and right-hand cutting direction make it well suited for through-hole and blind-hole reaming in ferrous and non-ferrous materials. Machinists and tool-and-die professionals install this reamer in a standard drill chuck or collet for CNC and manual machine tool operations.

The 300-1719 belongs to the OSG 300D series and is intended for general machining use across a wide range of shop environments. Its 7/8 inch flute length and 2-3/4 inch overall length keep the tool compact and rigid, reducing chatter and deflection during the reaming pass. The straight cylindrical shank fits standard drill chucks and collet holders without an adapter. This tool is appropriate for production runs and repair work where consistent hole size and surface finish are required.

Key Features

• Solid carbide construction for hardness and wear resistance in general machining
• Reamer diameter tolerance of +0.0001 to +0.0004 inches for precise hole sizing
• 4-flute straight geometry for smooth, controlled material removal
• Right-hand cutting direction compatible with standard spindle rotation
• Bright/uncoated finish suitable for use with cutting fluid on a wide range of workpiece materials
• Straight cylindrical shank for secure, concentric chuck or collet mounting

Compatibility

Designed as a standard OEM-style chucking reamer for general machining applications requiring a 0.1719 inch finished bore diameter in drill press, lathe, or CNC machining center setups.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practice. Secure the straight shank in a drill chuck or precision collet holder, ensuring runout is minimized before beginning the reaming pass. Always reduce spindle speed relative to drilling and apply appropriate cutting fluid for the workpiece material. Do not use this reamer to remove excessive stock; pre-drill or bore the hole to within 0.005 to 0.010 inches of final diameter before reaming.
