Hertel 2329399 Hand Reamer 0.1562 in 6 Flute Hss

Product Description

The HERTEL 2329399 is a hand reamer designed to finish and size pre-drilled holes to tight tolerances. It features a 0.1562-inch diameter cutting edge, six spiral flutes with a left-hand spiral direction, and a right-hand cutting action. The bright, uncoated high speed steel (HSS) construction delivers reliable hardness and edge retention across a range of workpiece materials. With a flute length of 1.63 inches and an overall length of 3.25 inches, this reamer is suited for precision hand-finishing operations in machine shops, maintenance environments, and field repair applications. Licensed machinists and mechanical tradespeople are the primary users of this tool.

This hand reamer is used in applications where a drilled hole must be brought to a precise final diameter with a smooth surface finish. The straight shank accepts standard drill press chucks and tap wrenches, making it practical for both bench and field work. It is well suited for light stock removal in ferrous and non-ferrous metals, as well as some plastics. The compact overall length makes it manageable in confined areas where a longer reamer would be difficult to control.

Key Features

• 0.1562-inch diameter for precision hole finishing to close tolerances
• Six spiral flutes provide smooth, chatter-resistant cutting action
• Left-hand spiral with right-hand cut helps clear chips away from the finished surface
• High speed steel construction resists wear across a broad range of materials
• Bright uncoated finish simplifies inspection and resharpening
• Straight shank fits standard chucks and tap wrenches

Compatibility

Designed as a standard hand reamer for use in drill presses, tap wrenches, or T-handle holders where a straight-shank 0.1562-inch reamer is required.

Installation Notes

Hand reamers are installed by machinists and mechanical maintenance tradespeople using a tap wrench or appropriate chuck. Always ensure the workpiece is securely clamped before reaming. Apply cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Never reverse the cutting direction while the reamer is engaged in the hole, as this can damage the cutting edges.
