Hertel 2329076 Hand Reamer 0.9688 in Hss 8 Flutes

Product Description

The HERTEL 2329076 is a straight-flute hand reamer designed for precision hole finishing in metal fabrication and machining applications. Built from high speed steel with a bright, uncoated finish, it delivers consistent bore diameter control when used with a tap wrench or adjustable handle. The reamer measures 0.9688 inches in diameter, features 8 straight flutes for smooth chip evacuation, and has a 5.31-inch flute length with a 10.63-inch overall length. The straight shank and right-hand cutting direction make it compatible with standard hand reaming setups. Machinists and tool-and-die professionals use this reamer to bring pre-drilled or bored holes to a precise finished diameter.

This hand reamer is suited for low-speed, manually controlled reaming operations where tight bore tolerances are required. Typical applications include finishing holes in mild steel, cast iron, aluminum, and similar machinable materials in job shop, maintenance, and production toolroom environments. It is intended for hand operation rather than machine spindle use, and is well suited for on-site or bench-work scenarios where a final pass is needed to hit a close-tolerance fit.

Key Features

• 0.9688-inch reamer diameter for precision bore finishing
• 8 straight flutes promote smooth cutting action and chip clearance
• High speed steel construction provides durability across a range of machinable metals
• Bright, uncoated finish suitable for general-purpose hand reaming
• 5.31-inch flute length delivers adequate cutting engagement for deep holes
• Right-hand cut with straight shank for use with standard tap wrenches or reamer handles

Compatibility

Designed as a general-purpose hand reamer for use in standard tap wrench or adjustable reamer handle setups requiring a 0.9688-inch finished bore diameter.

Installation Notes

Hand reamers are installed and operated by machinists or toolroom technicians using a tap wrench or similar manual driver. Always ensure the workpiece is securely clamped before beginning the reaming operation. Apply cutting fluid appropriate for the workpiece material to reduce heat and extend tool life. Advance the reamer with steady, consistent pressure and rotate in the cutting direction only — never reverse rotation, as this dulls the cutting edges.
