Hertel 83246991 Chucking Reamer 5 Solid Carbide

Product Description

The HERTEL 83246991 is a solid carbide chucking reamer designed to produce precise, finished bores in metalworking applications. Built to wire size 5, it cuts to a nominal diameter of 0.2055 inches with a tight tolerance of 0.0000 to 0.0002 inches, making it suitable for close-tolerance hole finishing where dimensional accuracy is critical. The reamer features four straight flutes ground from solid carbide for rigidity and edge retention. A bright, uncoated finish is standard. It seats in a straight cylindrical shank for use in drill presses, CNC machining centers, lathes, and manual chucking equipment operated by machinists and toolroom professionals.

This reamer is intended for finish-reaming operations in ferrous and non-ferrous metals where a drilled or bored hole requires accurate sizing. With a 1-inch flute length and a 3-inch overall length, it is suited to shallow-depth reaming in toolroom, production, and maintenance repair operations. The solid carbide construction makes it appropriate for harder materials and higher-speed applications where high-speed steel tooling would wear prematurely.

Key Features

• Wire size 5 diameter of 0.2055 inches with tolerance of 0.0000 to 0.0002 inches
• Solid carbide construction for rigidity and extended tool life in hard materials
• Four straight flutes for stable, chatter-resistant cutting action
• Straight cylindrical shank for compatibility with standard chucking equipment
• Bright uncoated finish suitable for a wide range of metalworking materials
• Right-hand cutting direction, standard orientation for reaming operations

Compatibility

Designed as a standard chucking reamer for use in drill presses, CNC machining centers, lathes, and manual chuck holders that accept straight cylindrical shanks.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists or toolroom personnel. Ensure the machine spindle and chuck are fully stopped and secured before inserting or removing the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not use this reamer to remove excessive stock — pre-drill or bore the hole to within recommended allowance before reaming.
