Osg 300-4724 Chucking Reamer 12mm Solid Carbide

Product Description

The OSG 300-4724 is a solid carbide chucking reamer designed for precision hole finishing in general machining applications. With a 12 mm (0.4724 inch) reamer diameter and a total overall length of 102 mm, this tool delivers tight diameter tolerances of +0.0001 to +0.0005 inches, making it well-suited for applications where bore accuracy and surface finish are critical. The six-flute straight geometry and right-hand cutting direction provide clean, consistent material removal in a variety of workpiece materials. Machinists and tool-room professionals install this reamer in standard chucks or collets on CNC machining centers, knee mills, and drill presses.

The 300-4724 is intended for general machining environments where a reliable, uncoated solid carbide reamer is needed for sizing holes to close tolerance. The 38 mm flute length provides adequate chip clearance for through-hole and blind-hole finishing operations. The straight cylindrical shank allows direct mounting in a wide range of standard toolholders without adapters. This reamer ships individually and is appropriate for both production runs and low-volume toolroom work.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding machining cycles
• Six straight flutes with right-hand cut for smooth, accurate hole finishing
• Diameter tolerance of +0.0001 to +0.0005 inches for precise bore sizing
• Bright uncoated finish suitable for use with standard cutting fluids
• Straight cylindrical shank for direct chuck or collet mounting
• Part of the OSG 300D series for general machining applications

Compatibility

Designed as a general-purpose solid carbide chucking reamer for standard machining operations requiring a 12 mm finished bore diameter. Fits any toolholder accepting a straight cylindrical shank of corresponding diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Secure the straight shank firmly in a precision collet or drill chuck before use, and verify runout with a dial indicator before taking a finishing pass. Always power down the spindle completely before changing or adjusting the tool. Do not exceed the recommended feed and speed parameters for solid carbide tooling in the workpiece material being machined.
