Hertel 2291177 Chucking Reamer Wire 17 Hss Straight

Product Description

The HERTEL 2291177 is a straight-flute chucking reamer designed to finish-ream holes to a wire gauge No. 17 diameter of 0.1730 inches. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers precise sizing in ferrous and non-ferrous metals. The straight-cylindrical shank mounts directly in a drill chuck or collet, making it a quick setup for drill press, lathe, or milling machine work. Right-hand cutting action and a 1.125-inch flute length make it well suited for through-holes and shallow blind-hole finishing operations in light to medium machining environments. Overall length is 4.5 inches.

This reamer is used in machine shop, toolroom, and production environments where a finished bore must hold tight tolerances in the No. 17 wire size range. Typical applications include bearing seat prep, dowel pin fit, and hydraulic or pneumatic component assembly where hole finish and diameter accuracy are critical. It is installed by machinists and tool-and-die professionals operating standard machine tools.

Key Features

• Wire gauge No. 17 cutting diameter of 0.1730 inches for precise hole finishing
• HSS construction provides wear resistance across a broad range of workpiece materials
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Straight flute geometry suits most through-hole and short blind-hole applications
• Bright uncoated finish for general-purpose use without added coating cost
• Right-hand cutting direction, standard for conventional machine tool setups

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet systems accepting a straight-cylindrical shank in the 0.1500 to 0.1999 inch diameter range.

Installation Notes

Installation is performed by machinists using a drill press, lathe tailstock, or milling machine with an appropriate chuck or collet. Always secure the workpiece fully and ensure the machine is at a safe stop before mounting or changing the reamer. Use cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Avoid using reamers to remove excessive stock; pre-drill holes to within 0.005 to 0.015 inches of final size using values appropriate to the specific material and application.
