Hertel 2412385 Chucking Reamer 19/32 in 6 Flute Cobalt

Product Description

The HERTEL 2412385 is a cobalt steel chucking reamer designed for precision hole finishing in machining applications. Built with 6 right-hand spiral flutes and a bright uncoated finish, this reamer delivers accurate sizing and smooth surface finishes in drilled holes. The straight-cylindrical shank mounts directly into standard chucks or collets on lathes, drill presses, and machining centers. With an overall length of 8 inches and a reamer diameter of 19/32 inch (0.5938 inch decimal), it is suited for production and toolroom environments where tight tolerances are required. Machinists and toolroom operators are the primary installers of this tool.

This chucking reamer is intended for use in metalworking applications where a pre-drilled hole must be brought to a precise finished diameter. The 2-inch flute length provides adequate cutting engagement for through-holes and blind holes in materials suited to cobalt steel tooling, including alloy steels, stainless steels, cast iron, and other tough materials where high-speed steel may lack the hardness and heat resistance needed. It is used in job shops, production facilities, and toolroom settings on standard machine tool setups.

Key Features

• Cobalt steel construction provides superior hardness and heat resistance compared to standard high-speed steel
• 6 right-hand spiral flutes for smooth cutting action and efficient chip evacuation
• Reamer diameter: 19/32 inch (0.5938 inch decimal) for precise hole finishing
• Straight-cylindrical shank for direct chuck or collet mounting
• Bright uncoated finish suitable for use with cutting fluids across a range of materials
• Overall length of 8 inches with a 2-inch flute length for versatile reach and engagement

Compatibility

Designed as a standard chucking reamer for use in lathes, drill presses, and machining centers equipped with chucks or collets accepting a straight-cylindrical shank in the 19/32 inch diameter class.

Installation Notes

Installation and use of this reamer is performed by machinists or toolroom professionals. Ensure the machine spindle is fully stopped and the tool is securely clamped in the chuck or collet before beginning operation. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. The pre-drilled hole should be sized to leave the recommended stock allowance for reaming before the tool is engaged.
