Osg 300-1610 Chucking Reamer 0.1610 in Solid Carbide

Product Description

The OSG 300-1610 is a solid carbide chucking reamer designed to bring bored or drilled holes to a precise finished diameter. Built to a 0.1610 inch decimal diameter (wire size 20), it holds a tight tolerance of +0.0001 to +0.0004 inches, making it suitable for close-tolerance work in production and maintenance machining environments. The 4-flute straight geometry with a right-hand cutting direction provides clean, consistent stock removal. At 2.75 inches overall length with a 0.875 inch flute length and a straight cylindrical shank, it seats reliably in standard chucks and collets. Machinists and tool-and-die technicians are the primary users of this tool.

The OSG 300-1610 is suited for general machining applications in both job-shop and production settings. Its solid carbide construction handles harder workpiece materials and higher cutting speeds than high-speed steel alternatives. The straight-shank configuration allows use in drill presses, CNC machining centers, and manual lathes equipped with appropriate collet or chuck toolholding. This is an uncoated bright-finish reamer intended for standard general-purpose reaming rather than specialized high-heat or corrosive-environment operations. It is sold individually.

Key Features

• Solid carbide construction for rigidity and wear resistance in general machining applications
• 0.1610 inch diameter (wire size 20) with a tolerance of +0.0001 to +0.0004 inches for close-tolerance hole finishing
• 4-flute straight geometry with right-hand cut for consistent, chatter-resistant stock removal
• Straight cylindrical shank for compatibility with standard chucks and collets
• Bright uncoated finish suitable for a wide range of standard workpiece materials
• Part of the OSG 300D series for general machining use

Compatibility

Designed as a general-purpose OEM-style chucking reamer for use in standard drill press, CNC, or lathe toolholding systems that accept a straight cylindrical shank.

Installation Notes

Chucking reamers are installed and removed by qualified machinists following standard machine tool lockout and energy-isolation procedures before tool changes. Ensure the workpiece and toolholding are secure and concentric before initiating the cut. Reamers remove only small amounts of material per pass; the pre-drilled or bored hole should be sized appropriately to leave only the correct finishing allowance. Do not use this tool as a drill or use it to remove excess stock beyond its intended finishing function.
