Hertel 72290174 Chucking Reamer Wire 17 0.1730 in Hss

Product Description

The HERTEL 72290174 is a wire-size chucking reamer designed to finish-ream drilled holes to precise tolerances. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer produces a 0.1730 inch diameter bore corresponding to wire gauge size 17. It features six straight flutes for smooth material removal and right-hand cutting action. The straight-cylindrical shank mounts directly in a drill chuck or collet on a drill press, lathe, or CNC machine. Overall length is 3.375 inches with a flute length of 1.125 inches. Machinists and tool-room technicians rely on this style of reamer for finishing close-tolerance holes in metal components where surface finish and dimensional accuracy are critical.

This chucking reamer is suited for machine reaming applications in job shops, maintenance repair operations, and production environments. It is appropriate for use in ferrous and non-ferrous metals where a wire-size hole in the 0.1500 to 0.1999 inch diameter range is required. The short flute length and straight shank make it compatible with standard drill press setups and turret lathes. It is sold individually and is well suited to low-volume toolroom use as well as production line changeovers requiring a precise wire-gauge bore size.

Key Features

• Wire gauge size 17, 0.1730 inch finished bore diameter
• Six straight flutes with right-hand cutting direction for smooth, chatter-resistant reaming
• HSS construction provides toughness and wear resistance across a range of common metals
• Bright, uncoated finish suitable for general-purpose machine reaming
• Straight-cylindrical shank for direct mounting in drill chucks or collets
• Overall length of 3.375 inches and flute length of 1.125 inches for compact tooling setups

Compatibility

Designed as a standard machine chucking reamer for use in drill presses, lathes, turret lathes, and CNC machining centers equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank in the 0.1500 to 0.1999 inch diameter range.

Installation Notes

Chucking reamers should be installed and operated by qualified machinists following standard shop practices. Power down and lock out the machine before securing the reamer in the chuck or collet. Ensure the shank is fully seated and the chuck is tightened before starting the spindle. Use appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish, and never hand-turn a machine reamer to avoid uneven edge wear.
