Hertel 72022403 Chucking Reamer 0.224in Hss Straight

Product Description

The HERTEL 72022403 is a high-speed steel (HSS) chucking reamer designed to bring bored or drilled holes to precise finished dimensions. With a 0.2240-inch diameter, a 6-inch overall length (OAL), and a 1.5-inch straight flute length, this tool delivers accurate, repeatable hole sizing in metalworking and machining applications. The bright, uncoated finish is standard for general-purpose HSS reamers used in production and job-shop environments. Six straight flutes and a right-hand cutting direction provide smooth material removal and a clean finish on the hole wall. The straight-cylindrical shank mounts directly in chucks, collets, or machine spindles without adapters.

This chucking reamer is suited for use in drill presses, lathes, milling machines, and CNC machining centers where a finish-reamed hole is required after a rough bore or drill operation. It is appropriate for ferrous and non-ferrous metals in both light production and maintenance-repair-operations (MRO) settings. Machinists, tool-and-die makers, and maintenance technicians reach for this size when working to tolerances in the 0.2240-inch range. The compact 0.15-pound weight makes it easy to handle during setup and tooling changes.

Key Features

• 0.2240-inch finished-hole diameter for precise, repeatable sizing
• HSS construction provides toughness and resistance to chipping on general-purpose materials
• Six straight flutes for smooth cutting action and clean hole walls
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits chucks and collets without additional adapters
• Bright, uncoated finish suitable for use with cutting fluids on a wide range of metals

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill press, lathe, or milling machine setups requiring a 0.2240-inch finish-reamed hole with a straight-cylindrical shank interface.

Installation Notes

Chucking reamers are installed by machinists and maintenance technicians using a drill chuck, collet, or floating reamer holder on a machine spindle. Always power down and lock out the machine before changing tooling. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not use a chucking reamer to remove excessive stock; pre-drill or bore the hole to within a few thousandths of final size before reaming.
