Hertel 83246926 Chucking Reamer 31/64 in Solid Carbide

Product Description

The HERTEL 83246926 is a solid carbide chucking reamer designed to finish-ream precision holes to a nominal 31/64 inch (0.4844 inch) diameter. With a straight flute geometry and a right-hand cutting direction, it delivers clean, accurate bores in a single pass. The 4 inch overall length and 1-1/2 inch flute length suit it to general-purpose machine-tool applications. Solid carbide construction provides the rigidity and wear resistance needed for tight-tolerance work. Diameter tolerance runs 0.0000 to 0.0003 inch, making this tool appropriate for close-fit hole finishing in production and jobshop environments alike. A bright, uncoated finish is standard.

This reamer is intended for use in CNC machining centers, drill presses, lathes, and other machine tools where the straight cylindrical shank can be gripped in a drill chuck, collet chuck, or toolholder. Six flutes distribute cutting load evenly and help maintain roundness in the finished bore. Typical applications include reaming holes in steel, cast iron, aluminum, and similar machinable materials where hole diameter, roundness, and surface finish must meet close engineering tolerances. Installation is performed by machinists and toolroom personnel in manufacturing and maintenance settings.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard or abrasive materials
• 31/64 inch (0.4844 inch) nominal diameter with a 0.0000 to 0.0003 inch tolerance for close-fit finishing
• Six straight flutes for balanced cutting action and consistent bore roundness
• Right-hand cutting direction compatible with standard spindle rotation
• Straight cylindrical shank for secure chuck or collet mounting
• Bright uncoated finish suitable for use with a wide range of cutting fluids

Compatibility

Designed as an OEM-style machine reamer for use in standard drill chucks, collet chucks, and toolholders that accept a straight cylindrical shank of the corresponding diameter.

Installation Notes

This tool is installed and operated by qualified machinists. Secure the straight shank fully in the chuck or collet before running the spindle, and verify runout with a dial indicator before production use. Always power down and lock out the machine before changing or adjusting tooling. Use appropriate cutting fluid for the workpiece material to maximize tool life and surface finish quality.
