Hertel 2291672 Chucking Reamer Wire Size 67 Hss

Product Description

The HERTEL 2291672 is a wire-gauge chucking reamer sized to number 67, designed for finish-reaming precision holes to a diameter of 0.0320 inches. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this tool is built for use in drill presses, lathes, and machining centers where tight bore tolerances are required. The straight-cylindrical shank seats securely in standard collets and chucks. At 1.375 inches overall length with a 0.5-inch straight flute, this compact reamer is suited for shallow, close-tolerance holes in metalworking and light manufacturing environments. Right-hand cutting direction is standard for conventional machining setups.

This reamer is used in production and job-shop environments where wire-gauge hole sizes demand accurate, repeatable results. Its compact geometry makes it particularly appropriate for work on small components where access and clearance are limited. Machinists, toolroom technicians, and precision fabricators working with ferrous and non-ferrous materials will find this tool fits standard chucking setups without modification. It is intended for finish-reaming operations following a drilled or bored pilot hole.

Key Features

• Wire-gauge number 67 diameter — 0.0320 inches for precision bore finishing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Bright, uncoated finish — no coating interference on close-tolerance applications
• Straight flute geometry for smooth cutting action and easy chip evacuation in through-holes
• Straight-cylindrical shank for secure seating in collets and drill chucks
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or standard chucking reamer for use in drill presses, lathes, and CNC machining centers accepting a straight-cylindrical shank in the corresponding collet or chuck size.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists or toolroom personnel. Ensure the spindle is fully stopped and the machine is de-energized before inserting or removing the tool from the chuck or collet. Always use the appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Do not use this reamer as a drill — it is a finish tool and requires a pre-drilled or bored pilot hole of the correct undersize.
