Hertel 2328912 Hand Reamer 23/32 in 8 Flutes Hss

Product Description

The HERTEL 2328912 is a straight-flute hand reamer designed to finish and size pre-drilled holes to a precise 23/32-inch diameter. Built from high-speed steel with a bright, uncoated finish, this reamer delivers consistent material removal and a clean bore surface in a wide range of ferrous and non-ferrous workpiece materials. The 8-flute configuration distributes cutting load evenly across the tool, reducing chatter and improving hole finish. With an overall length of 8.125 inches and a straight shank, it is sized for use in hand-held or light machine applications where accurate final hole sizing is required.

This hand reamer is suited for maintenance, toolroom, and production environments where holes must be finished to close tolerances. Typical applications include sizing holes for press-fit pins, bushings, and dowels in mechanical assemblies. The right-hand cutting direction is standard for conventional clockwise rotation or manual hand-turning. Machinists, tool and die makers, and maintenance technicians working on metal fabrication and mechanical repair operations are the primary users of this tool.

Key Features

• 23/32-inch (0.7188 inch decimal) reamer diameter for precise hole finishing
• 8 straight flutes for even cutting load distribution and smooth bore finish
• High-speed steel construction for durability across a range of workpiece materials
• Bright uncoated finish suitable for general-purpose reaming applications
• Right-hand cut with straight shank for standard toolholder and hand-use compatibility
• 8.125-inch overall length provides adequate reach for typical mechanical assemblies

Compatibility

Designed as a general-purpose hand reamer for use in standard straight-shank tool holders and hand-reaming applications requiring a 23/32-inch finished bore diameter.

Installation Notes

Always secure the workpiece firmly before reaming and ensure the pre-drilled pilot hole is undersized by the appropriate allowance for the material being reamed. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve hole finish. Turn the reamer only in the cutting direction — reversing rotation will damage the cutting edges. Machinists and maintenance technicians should follow standard shop safety practices, including eye protection and proper workholding, during all reaming operations.
