Hertel 79889259 Chucking Reamer 0.101 in Solid Carbide

Product Description

The HERTEL 79889259 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. With a reamer diameter of 0.101 inches and a tight diameter tolerance of 0.0000 to 0.0002 inches, this tool delivers consistent, accurate bore sizing. The 4-flute straight design and bright uncoated carbide construction make it well suited for applications where close tolerances are required. Machinists and tooling technicians install this reamer using a standard chuck or collet holder on a mill, drill press, or CNC machining center.

This chucking reamer is used in precision machining operations where drilled holes require final sizing to tight dimensional tolerances. Its compact overall length of 2.25 inches and 0.625 inch flute length make it appropriate for shallow hole finishing in ferrous and non-ferrous materials. The straight-cylindrical shank allows straightforward mounting in conventional and CNC machine tool spindles. It is suited for production runs and toolroom work where hole quality and repeatability are critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 0.101 inch diameter with a tolerance of 0.0000 to 0.0002 inches for tight bore sizing
• 4-flute straight flute geometry for smooth cutting action
• Bright uncoated finish for general-purpose material compatibility
• Straight-cylindrical shank for direct chuck or collet mounting
• Right-hand cutting direction for standard spindle rotation

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard chuck or collet-type machine tool spindles accepting a straight-cylindrical shank.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the straight shank firmly in a precision chuck or collet before use and verify runout with a dial indicator before reaming to tolerance. Power down the machine spindle completely before mounting or removing the reamer. Always use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole finish quality.
