Hertel 79888806 Chucking Reamer 0.044 in Solid Carbide

Product Description

The HERTEL 79888806 is a solid carbide chucking reamer designed for precision hole finishing in metalworking applications. With a 0.044-inch diameter and a diameter tolerance of 0.0000 to 0.0002 inches, this reamer delivers tight, repeatable sizing on through-holes and blind holes alike. The straight flute geometry and right-hand cut make it well-suited for finishing soft to medium-hardness metals where controlled chip flow is needed. At 1.5 inches overall length with a 0.375-inch flute length, this is a compact tool built for short-reach precision work. Machinists and toolroom technicians install it in standard drill chucks or collets on lathes, mills, and drill presses.

This chucking reamer is intended for precision reaming operations in machine shop and production environments. The straight-cylindrical shank allows direct mounting in standard drill chucks and collet systems without additional adapters. Its compact overall length suits applications where spindle clearance is limited or workpieces are thin. The four-flute design provides stable cutting action and good hole-wall finish in a range of ferrous and non-ferrous materials. This tool is appropriate for general machining operations where close-tolerance hole sizing is required.

Key Features

• 0.044-inch diameter with a tight tolerance of 0.0000 to 0.0002 inches for precision hole sizing
• Solid carbide construction for rigidity and wear resistance in demanding machining cycles
• Four-flute straight configuration supports stable cutting and consistent surface finish
• Right-hand cutting direction for standard spindle rotation compatibility
• Bright/uncoated finish maintains close dimensional accuracy without coating buildup affecting tolerance
• Straight-cylindrical shank fits standard drill chucks and collet holders without special tooling

Compatibility

Designed as an OEM-style precision chucking reamer for use in standard drill chucks and collet systems on lathes, mills, and drill presses requiring 0.044-inch diameter hole finishing.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the straight shank firmly in a collet or drill chuck rated for the spindle speed being used, and verify runout before cutting. Power down and de-energize the machine spindle completely before changing or inspecting the reamer. Do not use this tool as a drill; ream only pre-drilled or bored holes that are close to finished diameter.
