Hertel 5475231 Chucking Reamer 2 in Hss 12 Flute

Product Description

The HERTEL 5475231 is a straight-flute chucking reamer designed for precision hole finishing in metal and other machinable materials. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing and surface finish in through-holes and blind holes where tight tolerances are required. The 2-inch diameter reamer features a straight-cylindrical shank for secure chuck mounting and 12 flutes for smooth, stable cutting action. At 14 inches overall length with a 4-inch flute length, this tool is suited for deeper reach applications where standard-length reamers fall short. Right-hand cutting direction follows standard convention for most vertical and horizontal machining setups.

This reamer is used in metalworking and machining operations requiring accurate hole sizing to 2.0000 inches. Typical applications include production machine shops, toolrooms, and maintenance departments working with steel, cast iron, aluminum, and similar workpiece materials. It is well suited for use in drill presses, lathes, milling machines, and machining centers with appropriate RPM and feed rate settings for HSS tooling. Machinists and tool-and-die professionals are the primary users of this tool class.

Key Features

• 2.0000-inch finished diameter for precise hole sizing
• 12 straight flutes provide stable cutting and smooth bore surface finish
• HSS construction offers toughness and regrindability for long service life
• Bright, uncoated finish suitable for use with cutting fluids on a wide range of materials
• Straight-cylindrical shank mounts directly in standard drill chucks or collet holders
• 14-inch overall length with 4-inch flute length for extended reach applications

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, milling machines, and machining centers equipped with a chuck or collet capable of holding a straight-cylindrical shank at 2-inch diameter.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists familiar with speeds and feeds for HSS tooling. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool from the chuck or collet holder. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Inspect the reamer for chipping or wear before each use and do not exceed the tool diameter when selecting pilot hole size.
