Hertel 72008808 Chucking Reamer 0.0880 in Hss Straight Flute

Product Description

The HERTEL 72008808 is a high-speed steel chucking reamer designed for precision hole finishing in metal and machined components. With a cutting diameter of 0.0880 inches and a 3-inch overall length, this reamer delivers tight-tolerance final sizing in drilling and machining operations. The straight flute geometry and right-hand cutting direction suit it for standard CNC and manual lathe or drill press setups. A bright, uncoated finish means the HSS substrate runs as-ground, making it a straightforward choice for general-purpose reaming where coating is not required. Machinists and tool-and-die professionals are the primary users of this type of reamer.

This chucking reamer is suited for light-duty precision reaming in production and job-shop environments. The straight-cylindrical shank seats securely in standard drill chucks and collets, making it compatible with drill presses, lathes, and CNC machining centers. With a 3/4-inch flute length and 4 flutes, it is optimized for shallow-to-moderate depth passes on holes in the 0.0500 to 0.0999-inch diameter range. It is a practical fit for aerospace, automotive, and general metalworking applications that demand clean, accurate bore finishes.

Key Features

• 0.0880-inch cutting diameter for precision final-size reaming
• High-speed steel construction for durability across ferrous and non-ferrous materials
• 4-flute straight configuration for consistent chip evacuation and smooth bore finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits standard chucks and collets without adapters
• Bright uncoated finish allows direct inspection of cutting edge condition

Compatibility

Designed as a standard chucking reamer for use with drill presses, lathes, and CNC machining centers accepting a straight-cylindrical shank in the 0.0500 to 0.0999-inch diameter reamer range.

Installation Notes

This reamer is installed and operated by machinists and toolroom professionals. Secure the straight-cylindrical shank firmly in a drill chuck or collet before use, and verify spindle runout is within acceptable tolerance to avoid bell-mouthing the bore. Power down and lock out the machine spindle before changing or inspecting the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
