Hertel 2329514 Hand Reamer 1/4 in 6 Flute Hss

Product Description

The HERTEL 2329514 is a hand reamer designed to finish and size pre-drilled holes to precise tolerances. Built from high speed steel with a bright uncoated finish, it delivers clean, accurate cuts in a range of metals and materials. The reamer features a 1/4 inch diameter cutting profile, six spiral flutes with a left-hand spiral direction, and right-hand cutting action. The spiral flute geometry improves chip evacuation and surface finish compared to straight-flute designs. With a 2 inch flute length and 4 inch overall length, this tool suits bench work and in-place reaming tasks where hand-driven precision is required.

The HERTEL 2329514 is suited for maintenance, toolroom, and light manufacturing applications where a hand-driven reamer is needed to bring a hole to a finished 1/4 inch diameter. The straight shank accepts standard brace-style tap wrenches or adjustable T-handles. It is commonly used by machinists, millwrights, pipefitters, and maintenance technicians working on mechanical assemblies, pump housings, valve bodies, and similar components requiring close-tolerance hole finishing.

Key Features

• 1/4 inch (0.2500 inch) finished hole diameter
• Six spiral flutes for improved chip flow and surface finish
• Left-hand spiral with right-hand cutting direction
• High speed steel construction for durability across common metals
• Bright uncoated finish suited for general-purpose reaming
• Straight shank compatible with standard T-handle and tap wrenches

Compatibility

Designed as a general-purpose hand reamer for finishing 1/4 inch diameter holes in metalworking, maintenance, and toolroom applications where hand-driven operation is required.

Installation Notes

This tool is operated by hand using a tap wrench or T-handle — do not mount in a power drill or lathe without confirming the tool is rated for machine use. Always ensure the workpiece is securely clamped before reaming. Apply cutting fluid appropriate to the workpiece material to extend tool life and improve hole finish. Ream in a single forward direction; reversing under load can damage the cutting edges.
