Hertel 2329530 Hand Reamer 0.2656 in 6 Flutes Hss

Product Description

The HERTEL 2329530 is a hand reamer designed for precision hole finishing in metal fabrication, maintenance, and repair applications. With a reamer diameter of 0.2656 inches and a spiral flute geometry, it enlarges and smooths pre-drilled holes to tight tolerances. The tool is constructed from high speed steel (HSS) with a bright, uncoated finish. Six flutes provide consistent chip evacuation and surface contact during manual operation. The left-hand spiral direction combined with right-hand cutting produces a pushing action that helps prevent the tool from self-feeding, giving the operator greater control during hand reaming operations.

This reamer is suited for tool and die shops, general machining environments, and field maintenance work where a precise, hand-driven finish pass is required. The straight shank design allows it to seat securely in a standard tap wrench or reamer handle. At 4.25 inches overall length with a 2.13-inch flute length, it fits a wide range of shallow-to-moderate depth hole finishing tasks in ferrous and non-ferrous materials.

Key Features

• 0.2656 inch diameter for precision hole sizing
• Spiral flute geometry with left-hand spiral direction for controlled, non-self-feeding cut
• Right-hand cutting direction for standard manual reaming operation
• 6 flutes for consistent finish and chip clearance
• High speed steel construction for durability in ferrous and non-ferrous materials
• Bright, uncoated finish suitable for general-purpose use

Compatibility

Designed as an OEM-style hand reamer suitable for use with standard tap wrenches and reamer handles accepting straight-shank tooling in the applicable diameter range.

Installation Notes

Hand reamers are installed and operated by machinists, tool and die workers, and maintenance technicians using a tap wrench or equivalent hand driver. Always ensure the workpiece is securely fixtured before reaming. Apply cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Do not force the reamer through an undersized hole — ensure the pilot hole is drilled to the correct pre-ream diameter before use.
