Hertel 72025208 Chucking Reamer 0.252 in Hss 6 Flute

Product Description

The HERTEL 72025208 is a straight-flute chucking reamer designed for precision hole finishing in metal fabrication and machining applications. Ground from high-speed steel (HSS) with a bright, uncoated finish, this reamer produces accurate, smooth bores to a 0.2520-inch diameter tolerance. The tool features a straight-cylindrical shank for secure chuck engagement and 6 right-hand cutting flutes distributed across a 1.5-inch flute length. Overall length is 6 inches, making it compatible with standard drill press and CNC lathe toolholding. This is a standard-size, non-dowel-pin, non-over-under reamer suited for general-purpose finish reaming operations.

This chucking reamer is used in job shops, tool rooms, and production environments where holes must be brought to precise final diameter after drilling. It is appropriate for through-holes and blind holes in ferrous and non-ferrous materials. The 0.2520-inch diameter falls within the 0.2500-to-0.2999-inch decimal inch range for standard chucking reamers. Machinists, tool-and-die makers, and precision machine operators are the primary users.

Key Features

• 0.2520-inch finished bore diameter for precision hole sizing
• 6 straight flutes with right-hand cutting direction for smooth material removal
• High-speed steel construction for durability across a range of workpiece materials
• Bright uncoated finish suitable for use with cutting fluids
• Straight-cylindrical shank for compatibility with standard drill chucks and collets
• 6-inch overall length with 1.5-inch flute length for controlled reaming depth

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with straight-shank toolholding systems accepting the straight-cylindrical shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reaming operations and proper speeds and feeds for HSS tooling. Secure the shank fully in the chuck or collet before operation and verify runout to maintain bore accuracy. Always apply an appropriate cutting fluid during reaming to extend tool life and improve surface finish. Power down and de-energize the machine spindle completely before tool changes.
