Hertel 2329738 Hand Reamer 9/16 in 8 Flutes Hss

Product Description

The HERTEL 2329738 is a hand reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel with a bright, uncoated finish, it enlarges and smooths pre-drilled holes to tight tolerances. The reamer measures 9/16 inch (0.5625 inch decimal) in diameter, with a 3-1/4 inch flute length and a 6-1/2 inch overall length. Eight spiral flutes with a left-hand spiral direction and right-hand cutting direction provide smooth chip evacuation and a clean bore finish. This tool is used by machinists, tool-and-die makers, and maintenance technicians who need accurate, hand-driven hole sizing.

This reamer is suited for hand reaming operations on ferrous and non-ferrous metals in both shop and field maintenance environments. The straight shank allows use in a tap wrench or standard reamer holder. The spiral flute geometry helps reduce chatter during the cut, making it appropriate for finishing holes in fixtures, bushings, and close-tolerance assemblies. It is a single-unit tool intended for controlled, manual feed rather than machine-driven applications.

Key Features

• 9/16 inch diameter (0.5625 inch decimal) for precise hole sizing
• 8 spiral flutes with left-hand spiral for smooth chip flow
• Right-hand cutting direction for standard hand reaming operation
• High-speed steel construction for durability across a range of metals
• Bright, uncoated finish suitable for general-purpose use
• Straight shank compatible with standard tap wrenches and reamer holders

Compatibility

Designed as an OEM-style hand reamer for general metalworking applications requiring a 9/16 inch finished bore diameter.

Installation Notes

Hand reamers are installed and operated by machinists or maintenance technicians using a tap wrench or adjustable reamer handle. Secure the workpiece before reaming and apply cutting fluid appropriate for the workpiece material to extend tool life and improve finish quality. Always ream in the cutting direction only — do not reverse the reamer in the hole, as this dulls the cutting edges. Ensure the pilot hole is sized correctly prior to reaming to avoid excessive stock removal.
