Hertel 72294267 Chucking Reamer Wire 26 Hss 4 Flute

Product Description

The HERTEL 72294267 is a high-speed steel chucking reamer designed for precision hole finishing in metalworking applications. Sized to wire gauge 26 with a decimal diameter of 0.1470 inches, this reamer delivers tight-tolerance bores where drill bits alone are insufficient. The 4-flute spiral geometry with right-hand spiral direction provides smooth cutting action and efficient chip evacuation. At 3 inches overall length with a 1 inch flute length, the tool is sized for short, precise cuts on a drill press, lathe, or CNC setup. The straight-cylindrical shank seats securely in standard chucks without specialized toolholding.

This chucking reamer is suited for job shop, tool room, and production environments where repeatable hole sizing in wire gauge ranges is required. It is not configured as a dowel pin reamer or an over/under size reamer, making it a standard-tolerance finishing tool. Machinists and tool room operators use this type of reamer when hole location and finish must meet closer tolerances than a drill alone can achieve, particularly in ferrous and non-ferrous metals typical of general machining work.

Key Features

• Wire size 26 (0.1470 inch decimal diameter) for tight-tolerance hole finishing
• High-speed steel construction for durability across ferrous and non-ferrous materials
• 4-flute spiral design with right-hand spiral direction for smooth chip flow
• Straight-cylindrical shank compatible with standard drill chucks and collets
• 3 inch overall length with 1 inch flute length for controlled shallow cuts

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with chucks or collets accepting a straight-cylindrical shank at the 0.1470 inch diameter range.

Installation Notes

Installation is performed by machinists or tool room personnel. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet before operation. Always use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Inspect the reamer for wear or chipping before each use and never force a reamer through an undersized pilot hole.
