Hertel 79889283 Chucking Reamer 0.105 in Solid Carbide

Product Description

The HERTEL 79889283 is a solid carbide chucking reamer designed for precision hole finishing in metal fabrication and machining applications. With a nominal diameter of 0.105 inches and a tight diameter tolerance of 0.0000 to 0.0002 inches, this reamer delivers consistent, accurate results where hole size control is critical. The 4-flute straight flute geometry provides smooth cutting action and good chip evacuation. The bright, uncoated solid carbide construction offers excellent hardness and wear resistance, making it well suited for high-speed reaming of ferrous and non-ferrous materials. Machinists and tool and die technicians are the primary installers of this tool type.

This chucking reamer is used in CNC machining centers, manual lathes, and drill presses where a straight-cylindrical shank is required for chuck mounting. With an overall length of 2.25 inches and a flute length of 0.625 inches, it is sized for small-diameter, close-tolerance hole finishing in production and toolroom environments. Right-hand cutting direction is standard for conventional spindle rotation. It is appropriate for use in both job shop and production floor settings where precision bore sizing is required after drilling.

Key Features

• Solid carbide construction for hardness, wear resistance, and dimensional stability
• 4-flute straight flute design promotes smooth cutting and consistent chip flow
• Diameter tolerance of 0.0000 to 0.0002 inches ensures precise, repeatable hole sizing
• Bright, uncoated finish compatible with a wide range of cutting fluids and workpiece materials
• Straight-cylindrical shank mounts directly in standard chucks without adapters
• Right-hand cut for use with conventional clockwise spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in any machine tool equipped with a chuck or collet that accepts a straight-cylindrical shank at the stated diameter.

Installation Notes

This tool is installed and operated by machinists and CNC technicians. Power down and lock out the machine spindle before mounting or removing the reamer from the chuck. Ensure the shank is fully seated and the chuck is tightened to the machine manufacturer's specification before beginning a cut. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole finish quality.
