Hertel 72022551 Chucking Reamer 0.2255 in Hss Straight Flute

Product Description

The HERTEL 72022551 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in machining operations. Built with a straight-cylindrical shank and six straight flutes, it produces accurate, smooth bores in ferrous and non-ferrous workpieces. The 0.2255-inch cutting diameter falls within the 0.2000 to 0.2499 inch range, and the 6-inch overall length suits standard drill press, lathe, and CNC chuck setups. The bright, uncoated finish is typical for general-purpose HSS tooling used in job shops and production environments. Machinists and tool-and-die professionals install this reamer as a finishing pass after drilling to achieve tight dimensional tolerance and improved surface finish.

This chucking reamer is suited for general machining applications where a reamed hole is required to close dimensional tolerance. The straight-cylindrical shank allows direct chucking in drill chucks, collet chucks, or floating holders on vertical mills, lathes, and drill presses. The 1.5-inch flute length accommodates typical through-hole and shallow blind-hole reaming tasks in light to medium material stock. It is intended for right-hand cutting rotation and is sold individually.

Key Features

• 0.2255-inch cutting diameter for precision hole finishing
• HSS construction provides toughness and re-sharpenability for general-purpose shop use
• Six straight flutes with right-hand cutting direction for smooth material removal
• Straight-cylindrical shank for direct chucking in standard drill or collet chucks
• 6-inch overall length suits a wide range of machine setups
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy

Compatibility

Designed as an OEM-style chucking reamer for use in drill press, lathe, vertical mill, and CNC setups that accept a straight-cylindrical shank toolholder or drill chuck.

Installation Notes

A licensed machinist or trained toolroom operator should install and operate this reamer. Ensure the machine spindle is fully stopped and the tool is securely chucked before beginning any setup. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Follow standard shop safety practices and machine guarding requirements during operation.
