Hertel 79889184 Chucking Reamer 0.092in Solid Carbide

Product Description

The HERTEL 79889184 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. With a reamer diameter of 0.092 inches and a tight diameter tolerance of 0.0000 to 0.0002 inches, this tool delivers consistent, accurate bore sizing in ferrous and non-ferrous materials. The straight flute geometry and right-hand cutting direction make it well-suited for through-hole and blind-hole reaming operations. It features a straight cylindrical shank for secure chuck or collet holding and measures 2 inches in overall length with a flute length of 0.5 inches.

This reamer is intended for use in CNC machining centers, drill presses, and manual milling setups where close-tolerance hole finishing is required. The solid carbide construction provides rigidity and wear resistance needed when working in hardened steels, cast iron, aluminum alloys, and similar materials. It is a standard toolroom and production-floor item installed by machinists and toolroom technicians.

Key Features

• Solid carbide construction for rigidity and extended tool life in demanding materials
• Diameter tolerance of 0.0000 to 0.0002 inches for precision bore finishing
• Straight flute design with right-hand cut for clean chip evacuation in most reaming applications
• 4-flute configuration for improved surface finish and cutting stability
• Bright/uncoated finish suitable for use with cutting fluids across a wide range of workpiece materials
• Straight cylindrical shank compatible with standard chucks and collets

Compatibility

Designed as an OEM-style precision chucking reamer for use in standard straight-shank chuck and collet toolholding systems on CNC and manual machine tools requiring a 0.092-inch finished bore diameter.

Installation Notes

This tool is installed and operated by qualified machinists following standard toolroom practices. Secure the straight shank fully in a chuck or collet to the recommended grip depth before operation. Always apply appropriate cutting fluid for the workpiece material to extend tool life and achieve target surface finish. Inspect the reamer for chipping or wear before each use, as carbide tooling is brittle and should not be dropped or subjected to lateral shock loading.
