Hertel 2058196 Chucking Reamer 7/32 in Hss Ticn 6 Flute

Product Description

The HERTEL 2058196 is a straight-shank chucking reamer designed for precision hole finishing in metal machining operations. Built from high-speed steel (HSS) with a titanium carbonitride (TiCN) coating, it delivers extended tool life and improved wear resistance compared to uncoated HSS reamers. The reamer measures 0.2188 inches (7/32 inch) in diameter with a 5-inch overall length and a 1-1/4 inch flute length. Six right-hand spiral flutes produce a smooth, accurate bore finish. This tool is used by machinists and tool-and-die tradespeople on manual mills, lathes, and CNC machining centers where tight hole tolerances are required.

This chucking reamer is suited for reaming through-holes and blind holes in ferrous and non-ferrous materials in both job shop and production environments. The straight cylindrical shank seats directly in a drill chuck, collet chuck, or floating reamer holder. It is appropriate for applications where a nominal 7/32 inch finished bore diameter is specified, such as dowel pin hole preparation, bearing seat finishing, and close-tolerance assembly work.

Key Features

• 0.2188 inch (7/32 inch) reamer diameter for precise bore sizing
• HSS construction provides toughness and regrindability
• TiCN coating improves surface hardness and reduces tool wear
• 6 right-hand spiral flutes for smooth chip evacuation and finish
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• 5-inch overall length with 1-1/4 inch flute length suits typical stock thicknesses

Compatibility

Designed as a standard chucking reamer for use in drill chucks, collet chucks, and floating reamer holders accepting a straight cylindrical shank at the 7/32 inch diameter class.

Installation Notes

Chucking reamers are installed by machinists in machine tool spindles — ensure the workpiece and machine are fully stopped before changing tooling. Secure the shank firmly in the holder to prevent runout, which directly degrades bore finish and diameter accuracy. Use appropriate cutting fluid for the workpiece material to prolong tool life and achieve specified surface finish. Follow shop-standard speeds and feeds for HSS reamers; excessive speed or feed will accelerate TiCN coating wear.
