Hertel 2291755 Chucking Reamer Wire 75 Hss 3 Flute

Product Description

The HERTEL 2291755 is a wire-gauge chucking reamer sized at No. 75, designed to finish-ream precision holes to a diameter of 0.0210 inches. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance in light metals, plastics, and similar materials. The straight-cylindrical shank seats securely in standard drill chucks, collets, or machine spindles. With 3 straight flutes and a right-hand cutting direction, this reamer is suited for through-hole and blind-hole finishing operations on drill presses, milling machines, and CNC equipment. Overall length is 1 inch with a flute length of 0.5 inches.

This chucking reamer is intended for use in production and toolroom environments where precise hole sizing at the small end of the wire-gauge range is required. It is a standard choice for machinists, tool-and-die makers, and precision fabricators working with components that demand tight tolerance finishing in No. 75 wire-gauge holes. The compact 1-inch overall length suits work in confined areas or on small-scale parts.

Key Features

• Wire gauge No. 75 cutting diameter of 0.0210 inches for precision small-hole finishing
• HSS construction provides good wear resistance across a range of workpiece materials
• Bright, uncoated finish suitable for general-purpose reaming applications
• 3 straight flutes with right-hand cutting direction for smooth, consistent material removal
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Compact 1-inch overall length for use in tight spaces and on small components

Compatibility

Designed as a standard wire-gauge chucking reamer for use in drill presses, milling machines, CNC machining centers, and similar equipment fitted with chucks or collets that accept straight-cylindrical shanks in this size range.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel. Secure the straight-cylindrical shank firmly in a suitable chuck or collet before operation and verify runout before reaming. Power down and lock out the machine before changing or inspecting reamers. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve optimal surface finish.
