Hertel 2297257 Chucking Reamer 12.50mm Hss 6 Flute

Product Description

The HERTEL 2297257 is a straight-flute chucking reamer designed to bring bored or drilled holes to a precise finished diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent cutting performance in a wide range of ferrous and non-ferrous materials. The 12.50 mm (0.4921 inch) cutting diameter, 8-inch overall length, and 2-inch flute length make it well suited for moderate-depth finishing passes on CNC lathes, mills, and manual drill presses. Six right-hand cutting flutes distribute cutting forces evenly and produce a smooth bore finish to tight tolerances.

This chucking reamer is used in general machining and production environments where hole-finishing accuracy is required. The straight-cylindrical shank seats securely in standard chucks and collets without the need for Morse taper adapters, making it straightforward to install in both manual and CNC setups. Typical applications include finishing through-holes and blind holes in fixture plates, housings, brackets, and mechanical assemblies. It is not configured as a dowel-pin or over-under size reamer, so it is intended for standard nominal-diameter finishing work.

Key Features

• 12.50 mm (0.4921 inch) cutting diameter for precise hole finishing
• HSS construction provides toughness and resistance to wear in general-purpose machining
• 6 straight flutes with right-hand cutting direction for smooth, consistent bore surfaces
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank fits directly into standard chucks and collets
• 8-inch overall length with 2-inch flute length for moderate-depth hole finishing

Compatibility

Designed as a standard chucking reamer for use in CNC lathes, machining centers, and manual drill presses equipped with a compatible chuck or collet that accepts a straight-cylindrical shank of this diameter range.

Installation Notes

Chucking reamers are typically installed and operated by machinists in general machine shop environments. Before mounting, verify the shank seats fully and runs true in the chuck or collet to avoid runout that can widen the finished bore beyond tolerance. Always apply an appropriate cutting fluid for the workpiece material and run at reduced spindle speeds compared to drilling operations. Never force-feed a reamer; excessive feed rates will degrade surface finish and shorten tool life.
