Hertel 79890703 Chucking Reamer Wire Size 35 Solid Carbide

Product Description

The HERTEL 79890703 is a solid carbide chucking reamer ground to wire size 35, producing a finished bore diameter of 0.1100 inches with a tight tolerance of 0.0000 to 0.0002 inches. The bright, uncoated solid carbide construction delivers the rigidity and wear resistance needed for precise hole finishing in ferrous and non-ferrous materials. With an overall length of 2.25 inches and a flute length of 0.625 inches, this compact reamer is well-suited for close-tolerance work in machining centers and drill presses. Installation and operation are handled by machinists and toolroom professionals working to tight dimensional requirements.

This reamer is used in production and toolroom environments where accurate, repeatable hole sizing is critical. The straight cylindrical shank allows secure clamping in standard collet chucks, drill chucks, and precision holders. The 4-flute straight configuration suits through-hole and blind-hole finishing in a range of workpiece materials. It is a practical choice for applications requiring wire-gauge-sized bores in components where fit and finish tolerances are tight.

Key Features

• Solid carbide construction for high rigidity and extended tool life
• Wire size 35 designation, 0.1100 inches diameter with 0.0000 to 0.0002 inch tolerance
• 4-flute straight flute geometry for clean, consistent material removal
• Straight cylindrical shank for compatibility with standard collet and drill chuck holders
• Bright uncoated finish suitable for use with cutting fluids across common workpiece materials
• Right-hand cutting direction, standard for conventional reaming operations

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for any machine tool setup accepting a straight cylindrical shank in wire size 35 bore-finishing applications.

Installation Notes

Chucking reamers are installed and operated by machinists using collet chucks or precision drill chucks on machine tools such as drill presses, mills, or CNC machining centers. Ensure the machine spindle and workpiece are properly secured and aligned before beginning the reaming pass. Use an appropriate cutting fluid for the workpiece material to promote tool life and surface finish quality. Do not use a chucking reamer to remove excessive stock; pre-drill or bore the hole to within the recommended allowance before reaming.
