Hertel 45676558 Chucking Reamer 0.379 in Solid Carbide

Product Description

The HERTEL 45676558 is a solid carbide chucking reamer designed to finish-ream drilled or bored holes to a precise diameter of 0.379 inches. Solid carbide construction delivers superior hardness and wear resistance compared to high-speed steel, making it well suited for production environments where dimensional consistency and tool life are priorities. The straight flute geometry and right-hand cut produce clean, accurate bores in a wide range of ferrous and non-ferrous materials. With an overall length of 3.5 inches and a flute length of 1.25 inches, this reamer fits standard chuck setups on CNC machining centers, knee mills, and drill presses. It is installed and used by machinists, tool and die makers, and maintenance technicians who require tight hole tolerances.

This reamer is suited for finishing operations in machine shops, manufacturing facilities, and maintenance repair environments. It performs in both production and job-shop settings where hole quality and dimensional accuracy are required. The straight-cylindrical shank seats directly in a drill chuck or collet without additional adapters, simplifying setup. The bright, uncoated finish is appropriate for use with standard cutting fluids across a broad range of workpiece materials where a specialized coating is not required.

Key Features

• Solid carbide construction for extended tool life and dimensional stability
• 0.379 inches finished bore diameter with straight flute geometry for clean stock removal
• Right-hand cutting direction with 6 flutes for smooth, accurate hole finishing
• Straight-cylindrical shank for direct chuck or collet mounting without adapters
• Bright, uncoated finish compatible with standard cutting fluids
• Compact 3.5 inches overall length suits confined-reach applications

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collets on CNC machining centers, manual mills, and drill presses requiring a 0.379 inches finish-reamed bore diameter.

Installation Notes

This reamer is installed by machinists in a drill chuck or collet holder; ensure the shank is fully seated and the chuck is tightened securely before operation. Power down the spindle completely before mounting or removing the reamer. Always pre-drill or bore the hole to the appropriate undersize before reaming to avoid excessive tool load. Apply appropriate cutting fluid for the workpiece material to promote tool life and surface finish quality.
