Hertel 79889473 Chucking Reamer 0.132 in Solid Carbide

Product Description

The HERTEL 79889473 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 0.132-inch diameter and a tight tolerance of 0.0000 to 0.0002 inches, this reamer delivers accurate, repeatable bore sizing in a single pass. The straight flute geometry and right-hand cutting direction make it well suited for through-holes and short blind bores in ferrous and non-ferrous materials. At 2.5 inches overall length with a 0.75-inch flute length, it fits standard drill presses, CNC machining centers, and manual lathes equipped with collet or drill chuck toolholding. Machinists and toolroom technicians are the primary users of this tool.

This chucking reamer is intended for production and toolroom environments where hole diameter consistency is critical. Its straight cylindrical shank allows it to seat directly in standard collets and drill chucks without additional adapters. The bright, uncoated carbide surface is appropriate for dry cutting or light cutting fluid applications on aluminum, brass, cast iron, and mild steel. The compact flute length keeps deflection low when reaming shallow holes in thin workpieces or close-tolerance bores.

Key Features

• 0.132-inch reamer diameter with a tolerance of 0.0000 to 0.0002 inches for precision bore sizing
• Solid carbide construction for rigidity and wear resistance in demanding machining environments
• Straight flute design for smooth chip evacuation in through-holes
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight cylindrical shank for direct mounting in collets and drill chucks
• Bright, uncoated finish suitable for use with or without cutting fluid

Compatibility

Designed as an OEM-style replacement and standard toolroom chucking reamer for use in drill presses, CNC machining centers, and manual lathes with collet or drill chuck toolholding that accepts a straight cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by machinists and toolroom technicians. Ensure the machine spindle is fully stopped and de-energized before mounting or removing the reamer from the toolholder. Secure the straight shank firmly in a properly sized collet or drill chuck to prevent runout. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
