Hertel 72016751 Chucking Reamer 0.1675 in Hss 6 Flute

Product Description

The HERTEL 72016751 is a straight-flute chucking reamer designed for precision hole finishing in metal and similar materials. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing performance in drill press, lathe, and CNC applications. The reamer measures 0.1675 inches in diameter with a 4.5-inch overall length and a 1.125-inch flute length. The straight-cylindrical shank allows direct chucking in standard drill chucks or collets. With 6 flutes and a right-hand cutting direction, it produces smooth, accurate bores in a single pass. Machinists and toolmakers install this type of reamer as a finishing step after drilling to achieve close-tolerance hole dimensions.

This chucking reamer is suited for small-diameter hole finishing in general machining environments, including job shops, production floors, and maintenance departments. Its 0.1675-inch diameter falls within the 0.1500 to 0.1999-inch decimal inch reamer range, making it appropriate for tight-tolerance work where drilled holes require final sizing to precise fits. The HSS construction handles a range of ferrous and non-ferrous materials at conventional cutting speeds. It is sold individually and intended for use in stationary machine setups rather than hand reaming applications.

Key Features

• 0.1675-inch cutting diameter for precise small-bore finishing
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• 6 straight flutes with right-hand cutting direction for smooth, consistent stock removal
• Straight-cylindrical shank for secure seating in drill chucks and collets
• Bright, uncoated finish — no added coating to affect dimensional tolerance
• 1.125-inch flute length suitable for shallow to moderate hole depths at this diameter

Compatibility

Designed as an OEM-style machine reamer for use in drill presses, lathes, and CNC machining centers equipped with standard drill chucks or collet holders that accommodate a straight-cylindrical shank at this diameter range.

Installation Notes

Chucking reamers are installed by machinists in stationary machine setups — ensure the machine spindle and workpiece are properly aligned before operation to avoid bell-mouthing or oversizing the bore. Power down and de-energize the machine before changing or seating the reamer in the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not use this tool for hand reaming; it is designed for machine use only.
