Hertel 72034671 Chucking Reamer 0.4670 in 7 in Hss 6 Flute

Product Description

The HERTEL 72034671 is a straight-flute chucking reamer designed for precision hole finishing in metal workpieces. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing and smooth surface finishes in through-holes and blind holes. The reamer measures 0.4670 inches in diameter with a 7-inch overall length and a 1.75-inch flute length. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. Right-hand cutting direction and a 6-flute configuration provide consistent chip clearance and dimensional accuracy. This tool is handled by machinists, tool-and-die professionals, and maintenance technicians performing close-tolerance reaming operations.

This chucking reamer is suited for machine reaming applications where a precise, finished bore diameter of 0.4670 inches is required. It is appropriate for use in CNC machining centers, engine lathes, drill presses, and manual turret lathes. Common materials reamed include mild steel, cast iron, aluminum, and similar machinable metals. The uncoated HSS construction makes it straightforward to resharpen, which is common practice in production and job-shop environments. It falls within the 0.4000 to 0.4999 inch reamer diameter range category.

Key Features

Compatibility

Designed as a standard chucking reamer for use in any machine tool spindle accepting a straight-cylindrical shank at 0.4670 inches reaming diameter.

Installation Notes

Chucking reamers are installed by machinists and tooling technicians. Secure the shank firmly in a drill chuck or collet holder before starting the spindle, and ensure the workpiece is rigidly clamped. Apply cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Always bring the reamer up to speed before engaging the workpiece, and never run a reamer in reverse, as this dulls the cutting edges.
