Hertel 2329357 Hand Reamer 1/8 in 4 Flute Hss

Product Description

The HERTEL 2329357 is a hand reamer designed for precise hole finishing in metalworking and machining applications. Built from high speed steel (HSS) with a bright uncoated finish, this tool delivers clean, accurate sizing of pre-drilled holes by hand or with a tap wrench. It features a 1/8 inch diameter, spiral left-hand flute geometry with right-hand cutting action, a flute length of 1.5 inches, and a straight shank for straightforward chuck or wrench engagement. With four flutes and a 3 inch overall length, the 2329357 is suited for light-duty precision reaming work in machine shops, maintenance environments, and trade fabrication settings.

This reamer is intended for hand reaming operations where tight hole tolerances and smooth bore finishes are required. The spiral flute design helps pull chips away from the cutting edge and reduces chatter, making it well suited for finishing holes in steel, aluminum, brass, and similar materials. It is a practical tool for machinists, pipefitters, millwrights, and maintenance technicians who need accurate hole sizing without a power-driven setup.

Key Features

• High speed steel construction for durability in ferrous and non-ferrous materials
• Spiral left-hand flute geometry with right-hand cutting direction to clear chips effectively
• Bright uncoated finish suitable for general-purpose reaming applications
• Straight shank compatible with standard tap wrenches and chucks
• Four flutes for balanced cutting action and improved hole finish quality
• Compact 3 inch overall length for use in confined or standard workpiece setups

Compatibility

Designed as an OEM-style hand reamer for finishing 1/8 inch diameter holes in general metalworking and maintenance applications.

Installation Notes

This reamer is installed and operated by machinists or maintenance technicians using a tap wrench or adjustable wrench. Always ensure the workpiece is securely clamped and the pilot hole is properly sized before reaming. Apply cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Never force the reamer through the bore; back it out periodically to clear chips.
