Hertel 2291300 Chucking Reamer Wire Size 30 Hss

Product Description

The HERTEL 2291300 is a straight-flute chucking reamer designed to finish-ream holes to a precise wire gauge size 30 diameter of 0.1285 inches. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy in through-hole and blind-hole finishing operations on ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in drill chucks and collet holders on lathes, drill presses, and CNC machining centers. With 4 flutes and right-hand cutting action, it provides smooth material removal and accurate bore sizing without the need for resharpening in standard production volumes.

This reamer is suited for machine shop and light manufacturing environments where wire-size holes must be held to tight tolerances. It fits residential, commercial, and industrial machining applications involving small-diameter bore finishing. Machinists and tool-and-die technicians use this reamer when drilling alone cannot achieve the required hole diameter or surface finish. It is particularly well suited for applications that call for a 0.1285-inch finished bore diameter within the 0.1000 to 0.1499 inch reamer diameter range.

Key Features

• Wire size 30 diameter — 0.1285 inches finished bore
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Bright uncoated finish — suitable for general-purpose reaming without specialized coatings
• 4 straight flutes with right-hand cutting direction for standard machine reaming
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Compact overall length of 3.5 inches with a 0.875-inch flute length for short-reach hole applications

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet-style toolholders on lathes, drill presses, and machining centers capable of holding a straight-cylindrical shank in the wire-size diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with proper reaming feeds, speeds, and cutting fluids for HSS tooling. Always secure the workpiece and ensure the machine spindle is fully stopped before loading or removing the reamer. Use appropriate cutting fluid to extend tool life and improve bore finish. Do not use this reamer as a drill — it is designed for finishing pre-drilled or bored holes only.
