Osg 300-1910 Chucking Reamer Size 11 Solid Carbide

Product Description

The OSG 300-1910 is a solid carbide chucking reamer designed for precision hole finishing in general machining applications. It produces a reamed diameter of 0.1910 inches (wire gauge size 11) 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 provide clean material removal in through-holes and blind-holes. With an overall length of 2.75 inches and a flute length of 0.875 inches, this reamer is compact and well-suited for small-diameter work on manual and CNC machines. Machinists and tool room technicians are the primary users.

This reamer is intended for general machining applications where accurate hole sizing is required. It fits into a standard straight-shank chuck or collet, making it compatible with drill presses, lathes, and CNC machining centers. The solid carbide construction handles ferrous and non-ferrous materials in production and maintenance machining environments. The bright, uncoated finish is standard for this class of carbide reamer and performs well across a range of common workpiece materials without requiring supplemental coating.

Key Features

• Reamer diameter of 0.1910 inches, wire gauge size 11, with a tolerance of +0.0001 to +0.0004 inches
• Solid carbide construction for rigidity and wear resistance in precision reaming
• Straight flute, right-hand cut geometry for clean, accurate bore finishing
• 4-flute design for balanced cutting and consistent surface finish
• Straight cylindrical shank for use in standard chucks and collets
• Bright, uncoated finish suited for general-purpose machining without specialized coating requirements

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and CNC machining centers that accept a straight cylindrical shank. Part of the OSG 300D series for standard carbide reaming applications.

Installation Notes

This reamer is installed by a machinist or tool room technician into a compatible chuck or precision collet. Ensure the machine spindle and workpiece are properly secured before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore quality. Do not use this reamer to remove excessive stock; pre-drill or bore the hole to near-final size before reaming.
