Hertel 79891297 Chucking Reamer 6mm Solid Carbide

Product Description

The HERTEL 79891297 is a solid carbide chucking reamer designed to finish-ream holes to a precise 6 mm (0.2362 inch) diameter. With a 3-inch overall length and a 1-inch straight flute, this tool delivers tight diameter tolerances of 0.0000 to 0.0002 inches, making it suitable for applications where bore accuracy and surface finish are critical. The four-flute, straight-flute geometry provides stable cutting action on ferrous and non-ferrous materials. Right-hand cutting direction is standard. The bright, uncoated solid carbide construction offers rigidity and wear resistance in short-run and production environments. Machinists and toolroom technicians install this reamer in CNC machining centers, manual mills, and drill presses using standard chucks or collet holders.

This chucking reamer is used in precision hole-finishing operations across metalworking, tool and die, aerospace component, and general machining applications. The straight cylindrical shank seats directly in ER collets, drill chucks, or floating reamer holders. At 6 mm diameter, this tool fits work requiring metric bore specifications in both light production and prototype work. It is not configured as an over-size or under-size reamer, and it does not function as a dowel pin reamer.

Key Features

• Solid carbide construction for rigidity and extended tool life compared to HSS alternatives
• Tight diameter tolerance of 0.0000 to 0.0002 inches for precision bore finishing
• Four straight flutes for stable, chatter-resistant cutting action
• Bright, uncoated finish suitable for dry cutting or use with standard cutting fluids
• Straight cylindrical shank compatible with ER collets, drill chucks, and floating holders
• Right-hand cut geometry; standard for the majority of machine tool spindle configurations

Compatibility

Designed for use in CNC machining centers, manual mills, and drill presses equipped with standard chuck or collet tooling accepting a straight cylindrical shank at the 6 mm diameter range.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully in a collet or chuck to the manufacturer-recommended engagement depth before running the spindle. Power down and lock out the machine before changing or inspecting tooling. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
