Hertel 2412625 Chucking Reamer 31/32 in Cobalt Steel

Product Description

The HERTEL 2412625 is a cobalt steel chucking reamer designed for precision hole finishing in machine shop and production environments. Built with 8 spiral flutes in a right-hand cutting direction, it delivers smooth, accurate sizing of drilled or bored holes to a finished diameter of 0.9688 inches (31/32 inches). The straight-cylindrical shank seats securely in a drill chuck or collet holder. Cobalt steel construction provides heat resistance and edge retention when working harder workpiece materials. The bright, uncoated finish is suitable for general-purpose reaming across a range of ferrous and non-ferrous materials. This tool is installed and used by machinists, tool-and-die makers, and maintenance technicians performing precision bore work.

This reamer is suited for through-hole and blind-hole finishing operations on manual mills, CNC machining centers, drill presses, and lathes. The 10-inch overall length provides reach for deeper setups or extended-reach fixtures. The 2-5/8-inch flute length accommodates typical stock thicknesses encountered in general machining, toolroom work, and production reaming applications. Spiral fluting aids chip evacuation and produces a cleaner finish compared to straight-flute designs, particularly in tougher alloys.

Key Features

• Cobalt steel construction for heat resistance and durability in harder materials
• 8 spiral flutes with right-hand cutting direction for smooth chip evacuation
• Finished diameter of 0.9688 inches (31/32 inches) for precise hole sizing
• Straight-cylindrical shank for use in standard drill chucks and collet holders
• 10-inch overall length with 2-5/8-inch flute length for versatile reach
• Bright, uncoated finish suitable for general-purpose reaming applications

Compatibility

Designed as a general-purpose chucking reamer compatible with manual mills, CNC machining centers, drill presses, and lathes equipped with standard drill chucks or collet holders accepting a straight-cylindrical shank.

Installation Notes

This reamer is installed by machinists and toolroom professionals. Secure the straight-cylindrical shank firmly in a drill chuck or collet holder before operation. Ensure the workpiece is clamped securely and the pre-drilled or bored hole is sized appropriately undersize to allow for proper material removal. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality.
