Hertel 2328714 Hand Reamer 0.4062 in 6 Flute Hss

Product Description

The HERTEL 2328714 is a straight-flute hand reamer designed for precision hole finishing in metal and other rigid materials. It removes minimal stock to bring a drilled or bored hole to a tight, accurate diameter of 0.4062 inches. Constructed from high-speed steel (HSS) with a bright, uncoated finish, this reamer maintains a sharp cutting edge across a range of ferrous and non-ferrous materials. The 6-flute configuration provides smooth cutting action and improved surface finish. With an overall length of 5.25 inches and a flute length of 2.63 inches, it suits benchtop and field reaming tasks. Right-hand cutting direction is standard for manual operation. Machinists, toolmakers, and maintenance technicians install this type of reamer.

This hand reamer is suited for finishing operations in precision machining environments, tool-and-die work, and general metalworking maintenance. It is intended for use in manual reaming applications where a hand tool or low-speed driver provides controlled material removal. Typical applications include bearing seat preparation, bushing installation, and fitting pin bores to close tolerances. The straight shank allows direct use in hand tap handles or adjustable reamer holders. It is appropriate for use in both production shop and field repair scenarios where achieving a precise bore diameter is critical.

Key Features

• 0.4062 inch finished bore diameter for tight tolerance hole sizing
• 6 straight flutes for smooth, consistent material removal
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Bright, uncoated finish suitable for use with a range of cutting fluids
• Right-hand cutting direction for standard manual operation
• Straight shank compatible with standard hand reamer holders and tap wrenches

Compatibility

Designed as an OEM-style hand reamer for general precision metalworking applications requiring a 0.4062 inch finished bore diameter.

Installation Notes

Hand reamers are typically used by machinists and maintenance technicians. Secure the workpiece before reaming and apply an appropriate cutting fluid to reduce friction and extend tool life. Always rotate the reamer in the cutting direction only — reversing rotation can chip the cutting edges. Start the reamer squarely in the existing hole to avoid bell-mouthing or oversize conditions.
