Hertel 45675139 Chucking Reamer 0.1955 in Solid Carbide

Product Description

The HERTEL 45675139 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. With a reamer diameter of 0.1955 inches and an overall length of 3 inches, this tool is built for tight-tolerance applications where dimensional accuracy and surface finish are critical. The solid carbide construction provides superior rigidity and wear resistance compared to high-speed steel alternatives, making it well suited for harder materials and higher cutting speeds. It carries a bright, uncoated finish and features a right-hand cutting direction with four straight flutes.

This chucking reamer is intended for use in drilling and machining operations where a pre-drilled or bored hole must be brought to a precise final diameter. The straight cylindrical shank seats into a standard chuck or collet on a drill press, CNC machining center, or manual mill. A 1-inch flute length accommodates typical through-hole and blind-hole reaming tasks in the 0.1500 to 0.1999 inch diameter range. It is used by machinists, tool-and-die makers, and precision manufacturing shops handling production runs or one-off close-tolerance work.

Key Features

• Solid carbide construction for high rigidity and extended tool life in hard or abrasive materials
• 0.1955 inch reamer diameter for precision hole sizing within the 0.1500 to 0.1999 inch range
• Four straight flutes provide consistent chip evacuation and smooth bore finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• Bright, uncoated finish suitable for use with cutting fluids across a variety of workpiece materials
• Straight cylindrical shank for secure seating in drill chucks or collet holders

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for machine tools accepting a straight cylindrical shank in applications requiring a 0.1955 inch finished bore diameter.

Installation Notes

Chucking reamers are installed by machinists using a drill chuck or precision collet holder on a drill press, mill, or CNC machining center. Ensure the workpiece is securely fixtured and the spindle speed and feed rate are set per the reamer manufacturer guidelines for the workpiece material and diameter. Always apply appropriate cutting fluid to extend tool life and maintain bore finish quality. Inspect the shank and flutes for damage before use, and never attempt to rotate a reamer by hand against a workpiece under machine power.
