Hertel 72294226 Chucking Reamer Wire 22 Hss 4 Flute

Product Description

The HERTEL 72294226 is a high-speed steel (HSS) chucking reamer designed to finish-ream precision holes to a wire size 22 diameter of 0.1570 inches. With a right-hand spiral flute configuration and a straight-cylindrical shank, this reamer mounts directly in drill chucks, collets, or machine spindles for reliable, repeatable sizing. The 4-flute geometry balances chip evacuation with surface finish quality, making it a practical choice for production and maintenance machining environments. Overall length is 3.125 inches with a 1-inch flute length. Machinists, tool-and-die makers, and maintenance technicians use this reamer for close-tolerance hole finishing in ferrous and non-ferrous materials.

This chucking reamer is suited for use in drill presses, lathes, milling machines, and CNC machining centers where controlled hole sizing is required. It is appropriate for light stock removal following drilling, bringing holes to a precise finished diameter. Common applications include fixture fabrication, component assembly prep, and any operation requiring consistent hole geometry within the 0.1500 to 0.1999 inch decimal inch diameter range. The straight-cylindrical shank allows straightforward clamping without the need for specialized holders.

Key Features

• Wire size 22 diameter at 0.1570 inches for precise hole finishing
• Right-hand spiral flute design promotes smooth chip flow and clean bore surfaces
• 4-flute construction balances cutting efficiency with surface finish quality
• HSS tool material provides good wear resistance across a range of workpiece materials
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Compact 3.125-inch overall length suits benchtop and production machine setups

Compatibility

Designed as a standard chucking reamer for use in any machine tool spindle or chuck accepting a straight-cylindrical shank, suitable for applications requiring hole finishing in the 0.1500 to 0.1999 inch diameter range.

Installation Notes

Installation is performed by qualified machinists or maintenance technicians. Secure the straight-cylindrical shank fully in a drill chuck or collet before operation, and verify runout before taking finishing cuts. Power down and lock out the machine spindle completely before inserting or removing the reamer. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
