Hertel 2328458 Hand Reamer 5/32 Inch 6 Flute Hss

Product Description

The HERTEL 2328458 is a straight-flute hand reamer designed to finish-ream drilled holes to precise dimensions. Built from high speed steel (HSS) with a bright uncoated finish, this tool delivers accurate hole sizing in a wide range of metals and softer materials. It measures 5/32 inch (0.1562 inch) in diameter with a 3-1/4 inch overall length and features 6 straight flutes for smooth, controlled material removal. The right-hand cutting direction is standard for hand-reaming operations. Machinists, tool and die workers, and maintenance technicians use this reamer when a drilled hole requires final sizing to tight tolerance before assembly.

This reamer is suited for bench and hand operations where a drill press or CNC machine is not required. The straight shank allows it to be driven with a tap wrench or suitable hand driver. At 5/32 inch diameter, it is commonly used for light-duty precision work such as sizing pin holes, dowel holes, and close-tolerance fastener bores in sheet metal, mild steel, aluminum, brass, and similar materials. The compact 3-1/4 inch overall length makes it easy to control in confined workspaces.

Key Features

• 5/32 inch (0.1562 inch) reamer diameter for precise hole sizing
• 6 straight flutes for smooth cutting action and efficient chip clearance
• High speed steel construction for durability across ferrous and non-ferrous materials
• Bright uncoated finish — no coating buildup to affect tolerances
• Right-hand cut with straight shank for use with standard tap wrenches
• Compact 3-1/4 inch OAL suited for benchtop and close-quarter applications

Compatibility

Designed as a standard straight-shank hand reamer for use in any application requiring finish reaming of 5/32 inch diameter holes by hand or with a compatible tap wrench driver.

Installation Notes

Hand reaming should be performed after drilling to leave minimal stock for removal — typically 0.003 to 0.005 inch, though always follow job-specific engineering requirements. Apply cutting fluid appropriate for the workpiece material to reduce heat and improve finish quality. Turn the reamer only in the cutting direction; reversing rotation will dull the flutes. Secure the workpiece firmly before reaming to prevent movement that could cause an out-of-round bore.
