Hertel 2330058 Hand Reamer 1-1/8 in 10 Flutes Hss

Product Description

The HERTEL 2330058 is a spiral-flute hand reamer designed for precision hole finishing in metal fabrication, toolroom, and maintenance machining applications. Built from high-speed steel with a bright uncoated finish, this reamer delivers consistent dimensional accuracy when enlarging and smoothing pre-drilled or bored holes to a finished diameter of 1.125 inches. The spiral left-hand flute geometry with right-hand cut reduces chatter and pulls chips away from the cutting zone, resulting in a cleaner bore surface. With an overall length of 11.63 inches and a flute length of 5.81 inches, the 2330058 provides ample reach and cutting depth for standard through-hole and blind-hole reaming tasks. Straight shank design seats directly in a tap wrench or reaming handle.

This hand reamer is suited for toolroom machinists, maintenance technicians, and precision fabricators working with ferrous and non-ferrous metals. It is used to finish holes to tight tolerances in situations where a machine reamer is not practical or where hand-feed control is required. Typical applications include bearing bores, bushing fits, shaft-to-bore matching, and close-tolerance assembly work in industrial, HVAC equipment fabrication, and mechanical service settings.

Key Features

• 1.125 inch finished reaming diameter for accurate hole sizing
• 10-flute spiral geometry reduces chatter and improves surface finish
• Left-hand spiral with right-hand cut pulls chips out of the bore during operation
• High-speed steel construction provides hardness and wear resistance across a range of materials
• Bright uncoated finish allows visual inspection of cutting edges before use
• Straight shank compatible with standard tap wrenches and reaming handles

Compatibility

Designed as a general-purpose hand reamer for finishing 1.125 inch diameter holes in metalworking and maintenance machining applications where hand-fed reaming is specified.

Installation Notes

Hand reamers are installed by machinists or maintenance technicians using a tap wrench or adjustable reaming handle. The workpiece should be securely fixtured and the hole must be pre-drilled or bored to the correct undersize before reaming. Apply appropriate cutting fluid to the flutes and bore throughout the operation. Never reverse the reamer while it is engaged in a hole, as reversing dulls cutting edges and can cause binding.
