Hertel 72037674 Chucking Reamer 0.7670 in Hss 8 Flute

Product Description

The HERTEL 72037674 is a straight-flute high-speed steel (HSS) chucking reamer designed for precision hole finishing in machine tool applications. With a reamer diameter of 0.7670 inches and an overall length of 9.5 inches, it delivers accurate, repeatable bore sizing in metalworking operations. The bright uncoated finish and 8-flute configuration support smooth cutting action in a right-hand direction. This reamer is intended for use in CNC machining centers, manual lathes, and drill presses where close-tolerance hole sizing is required. Machinists and tool-and-die professionals are the primary installers and operators of this tool.

This chucking reamer is suited for production and job-shop environments where through-holes or blind holes require finishing to tight tolerances. The straight-cylindrical shank allows direct mounting in standard collet chucks, drill chucks, or toolholders. With a flute length of 2.5 inches, it accommodates typical bore depths encountered in ferrous and non-ferrous workpiece materials. It falls within the 0.7000 to 0.9999 inch reamer diameter range, making it appropriate for mid-range bore sizing work in general machining applications.

Key Features

• 0.7670 inch reamer diameter for precise hole finishing
• 8-flute straight-flute geometry for smooth, even cutting action
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• Bright uncoated finish suitable for a wide range of cutting fluid applications
• Straight-cylindrical shank for compatibility with standard chucks and collets
• Right-hand cutting direction, standard for conventional reaming operations

Compatibility

Designed as a standard chucking reamer for use in machine tool setups requiring a 0.7670 inch finished bore diameter with a straight-cylindrical shank interface.

Installation Notes

This tool is installed and operated by machinists in machine shop environments. Ensure the spindle and workpiece are properly secured before operation, and confirm the chuck or collet is rated for the shank diameter. Always use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Follow shop safety procedures and machine manufacturer guidelines when setting speeds and feeds.
