Hertel 45675618 Chucking Reamer 0.256 in Solid Carbide

Product Description

The HERTEL 45675618 is a solid carbide chucking reamer designed for precision hole finishing in machining applications. With a 0.256 inch diameter and a 6-flute straight configuration, it delivers consistent sizing and smooth surface finishes in drilled or bored holes. The bright, uncoated solid carbide construction provides the hardness and rigidity needed for accurate reaming in ferrous and non-ferrous materials. At 3.25 inches overall length with a 1.125 inch flute length, this reamer fits standard drill chuck setups and is sized for close-tolerance work where hole diameter consistency is critical.

This chucking reamer is suited for machine shop and production environments where holes in the 0.250 to 0.299 inch diameter range require finish reaming to tight tolerances. It installs in a drill press, CNC machining center, or lathe tailstock using a standard straight cylindrical shank. The right-hand cutting direction is compatible with conventional spindle rotation. Typical users include machinists and toolmakers performing finish reaming operations on metal workpieces in job shop or production settings.

Key Features

• Solid carbide construction for high rigidity and wear resistance
• 6-flute straight design for smooth, accurate hole finishing
• 0.256 inch diameter for precision sizing within the 0.250 to 0.299 inch range
• Bright/uncoated finish suitable for general-purpose reaming applications
• Straight cylindrical shank for direct chuck mounting
• Right-hand cutting direction for use with standard spindle rotation

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in drill presses, CNC machining centers, and lathes equipped with a drill chuck or collet accepting a straight cylindrical shank in the 0.250 to 0.299 inch diameter class.

Installation Notes

This tool is installed by machinists using a drill chuck or collet holder compatible with the straight cylindrical shank diameter. Ensure the machine spindle is fully stopped and the workpiece is securely fixtured before tool changes. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole finish quality. Inspect the reamer for chipping or wear before each use, as carbide tooling is brittle and sensitive to interrupted cuts or improper alignment.
