Hertel 2329555 Hand Reamer 0.2813 in 6 Flutes Hss

Product Description

The HERTEL 2329555 is a spiral-flute hand reamer designed for precision hole finishing in metal fabrication and machining applications. Built from high speed steel (HSS) with a bright uncoated finish, this reamer produces accurate, smooth bores to a nominal diameter of 0.2813 inches. The six-flute spiral geometry with left-hand spiral and right-hand cut provides excellent chip evacuation and a fine surface finish. With a flute length of 2.13 inches and an overall length of 4.25 inches, it is sized for bench work, jig fitting, and close-tolerance hand reaming tasks performed by machinists, tool and die workers, and maintenance technicians.

This hand reamer is suited for use in general metalworking, maintenance, repair, and operations (MRO) environments where a hand-driven or low-speed machine finish is needed on through-holes or blind holes. It is appropriate for steel, aluminum, brass, and similar machinable materials in both shop and field repair scenarios. The straight shank allows it to be held in a tap wrench, adjustable handle, or low-speed drill press chuck for controlled material removal on finish-size holes requiring tight dimensional tolerances.

Key Features

• 0.2813 inch reaming diameter for precision bore finishing
• Spiral flute geometry promotes smooth chip flow and reduces chatter
• Left-hand spiral with right-hand cut for controlled cutting action
• Six flutes deliver a fine surface finish in a single pass
• High speed steel construction provides hardness and wear resistance
• Bright uncoated finish suitable for use with standard cutting fluids

Compatibility

Designed as a standard straight-shank hand reamer for use with tap wrenches and compatible reamer handles in general metalworking and MRO applications.

Installation Notes

Hand reamers are installed and operated by machinists or maintenance technicians using a tap wrench or suitable reamer handle. Always apply cutting fluid appropriate for the workpiece material to extend tool life and improve surface finish. Ensure the hole is pre-drilled to the correct undersize before reaming, and apply steady, even forward pressure without reversing the cutter under load. Secure the workpiece firmly before beginning the operation to maintain alignment and prevent tool breakage.
