Hertel 79888681 Chucking Reamer 0.059 in Solid Carbide

Product Description

The HERTEL 79888681 is a solid carbide chucking reamer designed for precision hole finishing in metal and other hard materials. With a diameter of 0.059 inches and a diameter tolerance of 0.0000 to 0.0002 inches, it delivers tight, consistent sizing on finish-reamed bores. The four-flute straight design provides smooth chip evacuation and stable cutting action. The bright, uncoated carbide construction makes it well suited for use in short-run and inspection-critical applications where dimensional accuracy is the primary concern. Machinists and tool-and-die professionals install this reamer in a drill press, CNC machining center, or manual lathe chuck.

This reamer is used in machine shop environments for finish-reaming small-diameter holes where tolerance control is essential. The 0.059-inch diameter places it in the small-bore category, making it appropriate for precision instrument components, jig and fixture work, and close-tolerance production runs. The straight shank accepts standard collet chucks or drill chucks without modification. Right-hand cutting direction is standard for conventional spindle rotation.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Diameter tolerance of 0.0000 to 0.0002 inches for precision bore sizing
• Four straight flutes for smooth chip flow and consistent surface finish
• Straight cylindrical shank for direct mounting in collet or drill chuck
• Bright, uncoated finish suitable for general-purpose reaming applications
• Right-hand cutting direction for use with standard spindle rotation

Compatibility

Designed as an OEM-style replacement and general-purpose chucking reamer for machine shop applications requiring a 0.059-inch finished bore diameter with a straight cylindrical shank.

Installation Notes

Installation is performed by qualified machinists. Secure the straight shank firmly in a collet or drill chuck rated for the spindle speed being used. Power down and lock out the machine before changing or setting the reamer. Do not force the reamer through an undersized pilot hole; always pre-drill to the appropriate size before reaming to final diameter.
