Hertel 72036247 Chucking Reamer 0.6240 in Hss 8 Flute

Product Description

The HERTEL 72036247 is a straight-flute chucking reamer designed for precision hole finishing in metal fabrication and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer produces accurate, smooth bores to a diameter of 0.6240 inches. The straight-cylindrical shank seats securely in standard drill chucks or collets. With 8 flutes and a right-hand cutting direction, it removes material efficiently while maintaining tight tolerances. Overall length is 9 inches, with a flute length of 2.25 inches. This tool is intended for use in drill presses, lathes, or CNC machining centers where controlled reaming is required.

This chucking reamer is suited for production and job-shop environments where hole diameter consistency is critical. Typical applications include finishing drilled or bored holes in steel, cast iron, aluminum, and similar machinable metals. The straight-cylindrical shank makes it compatible with a wide range of standard machine spindles and toolholding systems. It is well matched to operations requiring a reamed finish in the 0.5000 to 0.6999 inch diameter range. Machinists, tool-and-die makers, and maintenance technicians working on close-tolerance assemblies are the primary users of this tool.

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with toolholding capable of accepting a straight-cylindrical shank in the 0.5000 to 0.6999 inch diameter range.

Installation Notes

This tool should be installed and operated by qualified machinists familiar with reaming procedures. Ensure the machine spindle is fully stopped and locked out before installing or removing the reamer from its holder. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve the desired surface finish. Do not exceed the recommended feed rate for the material being reamed, as forcing the tool can cause deflection or premature wear.
