Hertel 79889200 Chucking Reamer 0.094 in Solid Carbide

Product Description

The HERTEL 79889200 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. With a reamer diameter of 0.094 inches and a diameter tolerance of 0.0000 to 0.0002 inches, it delivers tight, repeatable bore sizing on small-diameter holes. The 4-flute straight design runs right-hand cut and is suited for use in CNC machining centers, drill presses, and manual mills. Overall length is 2 inches with a flute length of 0.5 inches. The bright, uncoated solid carbide construction provides rigidity and wear resistance for ferrous and non-ferrous materials.

This reamer is used in precision machining applications where a drilled or bored hole requires finishing to close tolerances. The straight cylindrical shank makes it compatible with standard collet chucks and drill chucks across a range of machine setups. It is well suited for small-diameter reaming work in aerospace, automotive, mold and die, and general precision manufacturing. The 0.094-inch diameter falls in the 0.0500 to 0.0999 inch decimal inch range, making it appropriate for fine-feature work where standard twist drills cannot achieve the required finish or dimensional accuracy.

Key Features

• Solid carbide construction for rigidity and extended tool life in precision applications
• Diameter tolerance of 0.0000 to 0.0002 inches for tight, consistent bore sizing
• 4-flute straight configuration for smooth cutting action on small-diameter holes
• Right-hand cutting direction, standard for conventional machine setups
• Bright uncoated finish for compatibility across a wide range of workpiece materials
• Straight cylindrical shank for direct chuck or collet mounting without adapters

Compatibility

Designed as an OEM-style chucking reamer for use in standard collet chucks and drill chucks on CNC machining centers, drill presses, and manual milling machines accepting straight cylindrical shank tooling.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before inserting or removing the reamer from the chuck or collet. Ensure the shank is fully seated and the chuck is tightened to the machine manufacturer's specification before running. Inspect the cutting edges for chipping before each use, as solid carbide tooling can be brittle if mishandled or dropped.
