Hertel 72020852 Chucking Reamer 0.2085 in Hss 6 Flute

Product Description

The HERTEL 72020852 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent bore sizing for machinists and toolroom professionals who require tight dimensional tolerances. The tool measures 5 inches in overall length with a flute length of 1.25 inches and a cutting diameter of 0.2085 inches. The straight-cylindrical shank allows secure seating in standard drill chucks and collet holders. With 6 flutes and right-hand cutting direction, it produces smooth, accurate finishes in ferrous and non-ferrous materials.

This chucking reamer is suited for machine shop, maintenance, and production environments where precise hole sizing is required. It is typically used in drill presses, lathes, CNC machining centers, and manual milling machines. The 0.2085-inch diameter falls within the 0.2000 to 0.2499 inch decimal inch reamer range, making it appropriate for applications requiring final bore finishing to close tolerances. Machinists, tool and die makers, and maintenance technicians are the primary users of this style of reamer.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel. Secure the straight-cylindrical shank fully into the drill chuck or collet before operation, and verify runout is within acceptable limits for the application. Always power down and de-energize the machine spindle before changing or inspecting tooling. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection when reaming.
