Hertel 2291326 Chucking Reamer Size 32 Hss 6 Flute

Product Description

The HERTEL 2291326 is a high-speed steel (HSS) chucking reamer designed to finish-ream holes to a precise wire gauge No. 32 diameter of 0.1160 inches. Built with 6 straight flutes and a straight-cylindrical shank, it fits standard drill press and CNC chucks without modification. The 3.5-inch overall length and 0.875-inch flute length make it well-suited for shallow, high-precision finishing passes in ferrous and non-ferrous materials. Machinists and toolroom operators rely on chucking reamers like this one to bring drilled or bored holes to final size with tight tolerances and a smooth surface finish. HSS construction provides the hardness and wear resistance needed for reliable performance in general production environments.

This reamer is used in machining operations where a wire-gauge-sized hole must be held to close dimensional tolerances. Typical applications include fixture plate work, jig boring, toolroom fabrication, and light production runs on drill presses, lathes, or CNC machining centers. The straight-cylindrical shank seats cleanly in collet chucks, drill chucks, and straight-shank toolholders. At 0.1160 inches nominal diameter, it falls within the 0.1000 to 0.1499 inch diameter range and is appropriate for any operation requiring a finished No. 32 wire-gauge hole.

Key Features

• Wire gauge No. 32 diameter: 0.1160 inches nominal for precise finish reaming
• 6 straight flutes for consistent chip evacuation and smooth bore finish
• HSS tool material offers hardness and wear resistance suitable for production use
• Straight-cylindrical shank compatible with standard collet and drill chucks
• 3.5-inch overall length with 0.875-inch flute length for shallow finishing passes
• Not an over/under size reamer — cuts to nominal wire size 32 diameter

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers equipped with straight-shank toolholding; fits any setup accepting a straight-cylindrical shank tool in the 0.1160-inch diameter class.

Installation Notes

Chucking reamers are installed and changed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the reamer from the chuck. Seat the straight-cylindrical shank fully and evenly in the chuck to prevent runout, which is the primary cause of oversized or out-of-round holes. Apply appropriate cutting fluid for the workpiece material, and never use a chucking reamer to remove more stock than manufacturer guidelines allow for the diameter class.
