Hertel 72008055 Chucking Reamer 0.0805 in Hss 4 Flute

Product Description

The HERTEL 72008055 is a straight-flute chucking reamer designed for precision hole finishing in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer produces accurate, smooth bores at a 0.0805-inch diameter. The straight-cylindrical shank seats securely in a drill chuck or collet for reliable, repeatable results. With four right-hand cutting flutes and a 0.75-inch flute length within a 3-inch overall length, it is well suited to light stock removal and close-tolerance finishing in small-diameter holes. Machinists and toolroom technicians working in job shops, maintenance facilities, and production environments rely on this type of reamer for final sizing of drilled or bored holes.

The HERTEL 72008055 is appropriate for reaming small-diameter holes in ferrous and non-ferrous metals where tight dimensional tolerances are required. The straight-cylindrical shank makes it compatible with standard drill chucks and collet systems on drill presses, lathes, and milling machines. The compact overall length of 3 inches suits benchtop and knee-mill setups where clearance is limited. This reamer is sold individually and is intended for professional machining and toolroom applications where consistent hole quality is critical.

Key Features

• 0.0805-inch finished bore diameter for close-tolerance hole sizing
• Four straight flutes with right-hand cutting direction
• High-speed steel (HSS) construction for durability in general machining
• Bright, uncoated finish — compatible with a wide range of cutting fluids
• Straight-cylindrical shank fits standard drill chucks and collets
• Compact 3-inch OAL with 0.75-inch flute length for light finishing passes

Compatibility

Designed as a standard chucking reamer for use in drill chucks and collet holders on drill presses, lathes, and milling machines requiring a 0.0805-inch finished hole diameter.

Installation Notes

Chucking reamers are installed and operated by qualified machinists. Secure the shank fully in a properly sized chuck or collet before use, and ensure the spindle is stopped completely before tool changes. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish. Do not use a reamer to remove excessive stock — pre-drill or bore to within a few thousandths of final diameter before reaming.
