Hertel 79890588 Chucking Reamer Wire 21 0.1590 in Solid Carbide

Product Description

The HERTEL 79890588 is a solid carbide chucking reamer in wire size 21, with a decimal diameter of 0.1590 inches and a tolerance of 0.0000 to 0.0002 inches. It features a straight flute geometry and a straight cylindrical shank, making it compatible with standard drill chucks and collet holders. The 4-flute cutting configuration and right-hand cutting direction deliver smooth, accurate bore finishing in ferrous and non-ferrous materials. At 2.5 inches overall length with a 0.75-inch flute length, this reamer is suited for close-tolerance reaming in confined workpieces. Machinists and tool-and-die professionals install this tool in CNC machining centers, drill presses, and manual lathes.

This chucking reamer is intended for precision bore finishing operations requiring tight dimensional control. The wire size 21 designation covers the decimal range of 0.1500 to 0.1999 inches, with this specific tool ground to 0.1590 inches. It is a fit for production and job-shop environments where hole quality and repeatability are critical. The bright, uncoated carbide surface is well suited for dry cutting or use with standard cutting fluids on a wide range of work materials.

Compatibility

Designed as a standard chucking reamer for use in drill presses, CNC machining centers, and manual lathes equipped with drill chucks or collet systems accepting a straight cylindrical shank.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with precision reaming operations. Ensure the machine spindle and workpiece are properly secured before beginning the reaming operation. Use an appropriate cutting fluid for the work material to extend tool life and improve bore finish. Do not use this reamer to remove excessive stock; pre-drill or bore the hole to within standard reaming allowances before use.
