Hertel 2328672 Hand Reamer 0.3438 in 6 Flute Hss

Product Description

The HERTEL 2328672 is a straight-flute hand reamer designed for precision hole finishing in metal and other materials. It operates at 0.3438 inches in diameter with 6 straight flutes and a right-hand cutting direction. The reamer is manufactured from high speed steel (HSS) with a bright, uncoated finish. Sized at 4.75 inches overall length and a 2.38-inch flute length, it is well-suited to manual reaming operations where close tolerances and smooth bore finishes are required. Machinists, tool and die workers, and maintenance technicians are the primary users of this tool.

This hand reamer is intended for bench and hand-reaming applications where precise hole sizing is performed after drilling. The straight flute geometry is appropriate for through-holes and general-purpose finishing in ferrous and non-ferrous metals. It is a standard fit for job shops, maintenance repair, and toolroom environments where controlled material removal and accurate bore diameters are critical to assembly fit.

Key Features

• 0.3438-inch reamer diameter for precise hole finishing
• 6 straight flutes for smooth, controlled material removal
• High speed steel construction provides durability in ferrous and non-ferrous materials
• Bright, uncoated finish — ready for use or compatible with aftermarket coatings
• Right-hand cutting direction, standard for conventional hand reaming
• Straight shank for secure chuck or tap-wrench holding

Compatibility

Designed as a general-purpose hand reamer for use in standard tap wrenches and suitable for manual reaming operations requiring a 0.3438-inch finished bore diameter.

Installation Notes

This reamer is intended for hand operation using a tap wrench or similar holding device — do not run it in a power spindle at high RPM without confirming suitability for machine use. Secure the workpiece before reaming and apply a suitable cutting fluid to extend tool life and improve surface finish. Inspect the flutes for damage before each use and replace if chipping or wear is observed.
