Hertel 2412328 Chucking Reamer 1/2 in 6 Flute Cobalt Steel

Product Description

The HERTEL 2412328 is a straight-shank chucking reamer designed for precision hole finishing in metal fabrication and machining applications. Built from cobalt steel with a bright, uncoated finish, it holds up under high-heat cutting conditions where high-speed steel would wear prematurely. The 0.5-inch diameter cutting head features 6 spiral flutes oriented for right-hand cutting, delivering a smooth, accurate bore finish. At 8 inches overall length with a 2-inch flute length, this reamer fits standard drill press and CNC lathe chuck setups. Machinists and tool-and-die workers reach for this tool when holding tight bore tolerances in steel, stainless, and high-alloy workpieces.

This reamer is suited for production and job-shop environments where consistent hole geometry is required after drilling. The straight-cylindrical shank seats directly in a drill chuck or collet without additional adapters, making it a straightforward drop-in for vertical mills, drill presses, and lathes. Typical applications include bore finishing in structural steel, alloy steel, and similar ferrous materials where cobalt-grade tooling provides the edge retention needed to maintain diameter accuracy across repeated passes.

Key Features

• Cobalt steel construction provides superior heat and wear resistance compared to standard HSS reamers
• 6 spiral flutes, right-hand cut, for smooth chip evacuation and consistent finish
• 0.5-inch diameter, bright uncoated finish, no over or under sizing
• Straight-cylindrical shank seats in standard drill chucks and collets without adapters
• 8-inch overall length with 2-inch flute length for reach in deep-hole applications
• Not configured as a dowel pin reamer — general-purpose bore finishing use

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, lathes, and vertical milling machines equipped with a standard drill chuck or collet accepting a straight-cylindrical shank at 0.5-inch diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the straight-cylindrical shank firmly in a drill chuck or collet before operation and confirm runout is within acceptable tolerance before cutting. Always power down and de-energize the machine spindle before changing tooling. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
