Hertel 2328755 Hand Reamer 0.4688 in 6 Flutes Hss

Product Description

The HERTEL 2328755 is a straight-flute hand reamer designed for precision hole finishing in metalworking applications. Built from high speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing and smooth surface finishes in through-holes and blind holes. The reamer measures 0.4688 inches in diameter, carries a 2.88-inch flute length, and runs 5.75 inches overall. Its 6-flute geometry distributes cutting load evenly, reducing chatter and improving roundness in the finished bore. This tool is operated by hand with a tap wrench or similar driver and is suited for final sizing work where tight tolerances are required.

The HERTEL 2328755 is used in machine shops, maintenance facilities, and fabrication environments where holes require finishing to a precise diameter after drilling. It is well suited for ferrous and non-ferrous metals in light to medium stock-removal passes. The straight shank accepts standard tap wrench chucks, making it accessible for bench work and field repair operations. Machinists, tool and die technicians, and maintenance mechanics commonly reach for this reamer when a drilled hole needs to be brought to final dimension with minimal material removal.

Key Features

• 0.4688-inch diameter for accurate final hole sizing
• High speed steel construction provides wear resistance across a range of metals
• 6-flute straight design distributes cutting forces evenly to minimize chatter
• Bright uncoated finish suitable for general-purpose reaming without additional coating considerations
• Right-hand cut with straight shank for use in standard tap wrenches
• 2.88-inch flute length accommodates typical through-hole and moderate-depth bore finishing

Compatibility

Designed as a general-purpose hand reamer for use with standard tap wrenches and compatible holders accepting a straight shank in the 0.4688-inch diameter class.

Installation Notes

Hand reamers are installed and operated by machinists or maintenance technicians using a tap wrench — power driving is not recommended and can damage flutes or cause oversize bores. Always secure the workpiece before reaming and apply appropriate cutting fluid to extend tool life and improve finish quality. Remove only the minimum stock necessary; hand reamers are finishing tools, not material-removal tools. Inspect the bore with a calibrated gauge after reaming to verify dimensional compliance before assembly.
