Hertel 72290133 Chucking Reamer Wire 13 0.1850 in Hss

Product Description

The HERTEL 72290133 is a high-speed steel (HSS) chucking reamer in wire size No. 13, designed to finish-ream drilled or bored holes to a precise diameter of 0.1850 inches. With a bright, uncoated HSS construction and 6 straight flutes, it delivers accurate sizing and smooth surface finishes in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in drill chucks, collets, and floating holders. Overall length is 3.5 inches with a flute length of 1.125 inches. This tool is used by machinists, tool-and-die makers, and maintenance technicians who need repeatable hole accuracy in production and repair applications.

This reamer is suited for light finishing cuts in through-holes and blind holes where a tight diameter tolerance is required. It is appropriate for use in machine tools such as drill presses, lathes, and milling machines with appropriate speed and feed settings. Right-hand cutting direction means it runs with standard clockwise spindle rotation. The wire-size designation No. 13 corresponds to a decimal diameter of 0.1850 inches, falling within the 0.1500 to 0.1999 inch diameter range. Typical applications include fixture work, jig building, and precision maintenance machining in industrial and shop environments.

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, lathes, milling machines, and similar machine tools equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by machinists or maintenance technicians familiar with machine tool operation. Ensure the machine spindle is fully stopped and the tool is securely seated in the chuck or collet before beginning a cut. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Do not use a chucking reamer to remove excessive stock; reamers are finish tools intended for light material removal after drilling or boring to size.
