Hertel 76153766 Chucking Reamer 0.507in Hss 6 Flute

Product Description

The HERTEL 76153766 is a straight-flute chucking reamer designed for precision hole finishing in metal machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing of drilled or bored holes to a finished diameter of 0.5070 inches. The straight-cylindrical shank seats securely in a drill chuck or collet, and the 6-flute geometry provides smooth, consistent cutting with right-hand rotation. At 8 inches overall length with a 2-inch flute length, this reamer suits standard machine tool setups where reach and rigidity are both required.

This chucking reamer is used in machine shop and production environments for finishing through-holes and blind holes in ferrous and non-ferrous materials. It is intended for use in drill presses, lathes, and CNC machining centers where the reamer is held in a chuck or collet and fed axially into a pre-drilled hole. Typical applications include close-tolerance bore finishing in job shops, maintenance and repair operations, and general manufacturing where hole quality and dimensional accuracy are critical.

Key Features

• 0.5070 inch finished reaming diameter for precise hole sizing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• 6 straight flutes with right-hand cutting direction for smooth material removal
• Bright uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank for direct chuck or collet mounting
• 8 inch overall length with 2 inch flute length for balanced reach and rigidity

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank in the 0.5000 to 0.6999 inch diameter range.

Installation Notes

Installation is performed by qualified machinists. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet before operation, and ensure the machine spindle is fully stopped before tool changes. Always pre-drill or bore the hole to the appropriate undersize before reaming, and apply a suitable cutting fluid to extend tool life and improve finish quality. Do not use a reamer to remove excessive material in a single pass.
