Hertel 45674918 Chucking Reamer 0.1640 in Solid Carbide

Product Description

The HERTEL 45674918 is a solid carbide chucking reamer designed to finish-ream precision holes to a nominal diameter of 0.1640 inches. Solid carbide construction provides superior rigidity and wear resistance compared to high-speed steel, making it well suited for demanding materials where dimensional accuracy and surface finish are critical. The tool features a bright, uncoated finish, four straight flutes, and a right-hand cutting direction. With an overall length of 2.75 inches and a flute length of 0.875 inches, it is sized for close-tolerance reaming operations on small-diameter bores in production and maintenance environments.

This chucking reamer is used in machine tool applications where a chuck or collet holds the shank directly in a drill press, machining center, or lathe. The straight-cylindrical shank ensures positive, concentric seating in standard toolholding. It is appropriate for ferrous and non-ferrous materials in job shops, toolrooms, and precision manufacturing facilities. Machinists, tool and die makers, and CNC operators are the typical end users. It is not configured as an over-size, under-size, or dowel pin reamer.

Key Features

• Solid carbide body for high rigidity and extended tool life in hard or abrasive materials
• 0.1640 inch nominal reaming diameter for precise bore finishing
• Four straight flutes with right-hand cutting direction for clean, consistent material removal
• Bright uncoated finish suitable for use with cutting fluids across a broad range of workpiece materials
• Straight-cylindrical shank for direct chuck or collet mounting
• Compact 2.75 inch overall length for use in tight setups and short-reach applications

Compatibility

Designed as a standard chucking reamer for use in any machine tool equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank in the corresponding diameter range.

Installation Notes

Installation is performed by machinists or toolroom personnel. Secure the straight-cylindrical shank concentrically in a drill chuck or collet and verify runout before cutting. Always apply an appropriate cutting fluid for the workpiece material and ensure the spindle is at a safe stop before changing or inspecting the tool. Do not use this reamer for hand-reaming operations; it is designed for machine-spindle use only.
