Hertel 45676657 Chucking Reamer 0.396 in Solid Carbide

Product Description

The HERTEL 45676657 is a solid carbide chucking reamer designed to finish-size drilled or bored holes to tight tolerances. With a 0.396-inch cutting diameter and six straight flutes, it delivers consistent bore quality in a single pass. The bright, uncoated carbide construction handles a wide range of ferrous and non-ferrous materials without the dimensional offset introduced by coated tools. Overall length is 3.5 inches with a 1.25-inch flute length and a straight cylindrical shank for direct chuck mounting. This tool is used by machinists and tool-and-die professionals wherever repeatable hole sizing is required.

This reamer is suited for machine shop, production, and maintenance applications where hole diameter falls within the 0.350 to 0.399-inch range. The straight shank mounts directly in drill press, CNC, or manual lathe chucks without an adapter. The right-hand cutting direction is standard for conventional spindle rotation. It is a single-piece, solid carbide tool — no inserts, no brazed tips — making it appropriate for applications demanding stability and deflection resistance in small-diameter finish reaming.

Key Features

• 0.396-inch cutting diameter for precise finish sizing in the 0.350 to 0.399-inch range
• Six straight flutes provide stable cutting action and clean chip evacuation
• Solid carbide construction resists deflection and maintains diameter accuracy
• Bright, uncoated finish eliminates coating-thickness variation for true nominal diameter performance
• Straight cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cut for use with conventional clockwise spindle rotation

Compatibility

Designed for use in standard drill press, CNC machining center, or manual lathe chucks accepting a straight cylindrical shank. Suitable for finish reaming holes in the 0.350 to 0.399-inch diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists. Ensure the workpiece is fully secured and the spindle is at the correct speed and feed for reaming before engaging the tool. Always bring the spindle to a complete stop before tool changes or workpiece adjustments. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
