Hertel 2328573 Hand Reamer 1/4 in 6 Flute Hss

Product Description

The HERTEL 2328573 is a straight-flute hand reamer designed to finish and size drilled holes to precise tolerances. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance in ferrous and non-ferrous metals, plastics, and similar materials. The 1/4-inch diameter reamer features 6 straight flutes and a right-hand cutting direction, producing a smooth bore finish when driven by hand with a tap wrench or adjustable handle. At 4 inches overall length with a 2-inch flute length and a straight shank, it fits standard reamer drivers used in machine shops, maintenance environments, and field service applications.

This hand reamer is suited for light material removal after drilling, typically used to bring a hole to final size and surface finish before assembly. It is appropriate for use in metalworking, maintenance and repair operations (MRO), and precision fitting tasks where tight hole tolerances are required. The straight-shank design accepts standard hand-reamer drivers and tap wrenches available in most tool inventories. It is well-suited for machinists, millwrights, and maintenance technicians working on close-tolerance assemblies.

Key Features

• 1/4-inch (0.2500 inch) diameter for precise hole finishing
• 6 straight flutes for smooth, consistent material removal
• High-speed steel (HSS) construction for durability in ferrous and non-ferrous materials
• Bright, uncoated finish — suitable for use with cutting fluids
• Right-hand cutting direction; driven with a standard tap wrench or reamer handle
• Straight shank for easy chuck or driver engagement

Compatibility

Designed as an OEM-style hand reamer for use in standard tap wrenches and adjustable reamer handles that accept straight-shank tooling at 1/4-inch diameter.

Installation Notes

Hand reamers are installed and operated by machinists or maintenance technicians using a tap wrench or adjustable handle — not a power drill. Always apply cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Apply light, consistent downward pressure while turning clockwise; never reverse the cutting direction under load, as this dulls the flutes. Secure the workpiece firmly before reaming to prevent movement that could cause out-of-round results.
