Hertel 72035892 Chucking Reamer 0.589 in Hss 8 Flute

Product Description

The HERTEL 72035892 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright uncoated finish, it delivers accurate sizing to a 0.5890-inch diameter. The 8-inch overall length and 2-inch flute length make it well-suited for moderate-depth bores in drill press, lathe, or milling machine setups. With 8 flutes and a right-hand cutting direction, this reamer produces a clean, consistent surface finish on through and blind holes. The straight-cylindrical shank allows direct chucking in standard drill chucks or collet holders without additional adapters.

This chucking reamer is intended for production and maintenance machine shops, toolrooms, and general metalworking operations. It is a standard finish reamer for use after drilling to bring a hole to a close-tolerance final diameter. Typical applications include sizing holes for press fits, locating pins, and precision bearing bores in ferrous and non-ferrous materials. Licensed machinists, toolmakers, and CNC machine operators are the primary users of this tool.

Key Features

• HSS construction provides durability across a range of workpiece materials
• 8 straight flutes for smooth cutting action and consistent chip evacuation
• Right-hand cutting direction, compatible with standard spindle rotation
• Bright uncoated finish suitable for general-purpose reaming without coolant restrictions
• Straight-cylindrical shank for direct chucking in drill chucks or collet holders

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and milling machines equipped with a drill chuck or straight-shank collet holder accepting a 0.5890-inch diameter tool.

Installation Notes

Chucking reamers are installed and operated by machinists following standard machine shop practices. Power down and lock out the machine spindle before securing or removing the tool from the chuck or collet holder. Always run the reamer at the appropriate reduced speed relative to drilling, and apply cutting fluid as needed for the workpiece material to extend tool life and improve finish quality. Do not reverse spindle rotation while the reamer is engaged in the workpiece.
