Hertel 2328870 Hand Reamer 0.6562 in 8 Flutes Hss

Product Description

The HERTEL 2328870 is a straight-flute hand reamer designed for precision finishing of bored or drilled holes to tight tolerances. Built from high-speed steel with a bright, uncoated finish, this reamer delivers consistent material removal in a range of shop and field applications. It measures 0.6562 inches in diameter with a 3.69-inch flute length and a 7.38-inch overall length. Eight evenly spaced flutes provide smooth, controlled cutting action with a right-hand cut direction. The straight shank allows direct mounting in standard reamer drivers or tap wrenches. Machinists, toolmakers, and maintenance mechanics rely on this style of reamer for final hole sizing where finish and dimensional accuracy matter.

This hand reamer is suited for use in metalworking, maintenance, and repair operations where a hole must be brought to a precise final diameter by hand. Typical applications include finishing holes in ferrous and non-ferrous metals prior to bearing, bushing, or pin installation. The 0.6562-inch diameter corresponds to a 21/32-inch nominal size, making it appropriate for achieving close-tolerance fits in general mechanical assembly and repair work across manufacturing and industrial maintenance environments.

Key Features

• 0.6562-inch cutting diameter for precise 21/32-inch nominal hole sizing
• High-speed steel construction for durability across ferrous and non-ferrous materials
• 8 straight flutes for smooth, even stock removal and consistent finish
• Right-hand cut direction with straight shank for standard driver compatibility
• Bright, uncoated finish suitable for general-purpose hand reaming applications
• 3.69-inch flute length provides adequate engagement depth for typical hole depths

Compatibility

Designed as a general-purpose hand reamer for use in standard tap wrenches or reamer drivers accepting a straight-shank tool at the 0.6562-inch nominal diameter.

Installation Notes

Hand reaming should be performed by a qualified machinist or maintenance mechanic using a properly sized tap wrench or reamer driver. Always ensure the workpiece is securely clamped before beginning the reaming operation. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never reverse the rotation of a hand reamer during extraction, as this can damage the cutting edges.
