Hertel 72022353 Chucking Reamer 0.2235in 6-flute Hss

Product Description

The HERTEL 72022353 is a 6-flute high-speed steel (HSS) chucking reamer designed for precision hole finishing in metal. With a reamer diameter of 0.2235 inches and an overall length of 6 inches, it is built for use in drill presses, lathes, and CNC machining centers where tight bore tolerances are required. The straight-cylindrical shank seats securely in standard chuck holders. The bright, uncoated finish is standard for general-purpose HSS reamers used in a wide range of ferrous and non-ferrous materials. This tool is installed and operated by machinists and toolroom technicians performing production or maintenance machining work.

This chucking reamer is suited for general metalworking applications where a reamed finish bore is required after drilling. The 1.5-inch flute length provides adequate cutting surface for shallow-to-medium depth holes. Right-hand cutting direction makes it compatible with standard spindle rotation on conventional machine tools. Typical applications include precision shaft bore fitting, bearing seat preparation, and dowel hole finishing in job shop, production machining, and maintenance repair environments.

Key Features

• 0.2235 inch reamer diameter for precision bore finishing within the 0.2000 to 0.2499 inch diameter range
• 6-flute straight flute geometry for smooth cutting action and improved surface finish
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous workpiece materials
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• Straight-cylindrical shank for secure seating in standard chucks and collets
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with standard straight-bore chucks or collet systems accepting a straight-cylindrical shank.

Installation Notes

Installation and operation should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and power is locked out before mounting or removing the reamer from the chuck. Use the correct pre-drill diameter per standard reaming allowance practice to avoid overloading the flutes. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish quality.
