Hertel 8272502 Chucking Reamer 0.616 in Hss 8 Flute

Product Description

The HERTEL 8272502 is a straight-flute chucking reamer designed for precision hole finishing in metalworking and machining applications. It measures 0.6160 inches in diameter with a 9-inch overall length and a 2.25-inch flute length. Constructed from high-speed steel (HSS) with a bright, uncoated finish, this 8-flute reamer delivers a clean, accurate bore in a right-hand cutting direction. The straight-cylindrical shank allows secure mounting in standard drill chucks, collet chucks, and machine spindles. It is installed and used by machinists, tool-and-die makers, and maintenance technicians requiring tight-tolerance reamed holes.

This reamer is suited for production and maintenance machining operations where a finished bore in the 0.5000 to 0.6999 inch diameter range is required. Typical applications include reaming pre-drilled or bored holes in ferrous and non-ferrous metals on drill presses, lathes, and milling machines. The 8-flute configuration provides a smooth surface finish and distributes cutting load evenly, making it appropriate for both short-run and repetitive production work where hole quality and dimensional accuracy are critical.

Key Features

• 0.6160-inch reamer diameter for precise hole finishing within the 0.5000 to 0.6999 inch range
• 8 straight flutes for smooth surface finish and balanced cutting load
• HSS construction provides toughness and wear resistance across a range of workpiece materials
• Bright, uncoated finish maintains consistent dimensional tolerance without coating buildup
• Straight-cylindrical shank for compatibility with standard chucks and collet holders
• Right-hand cutting direction, consistent with conventional machine reaming practice

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill presses, lathes, milling machines, and similar machine tools equipped with drill chucks or collet holders accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by qualified machinists. Secure the straight-cylindrical shank firmly in a drill chuck or collet before operation and verify runout is within acceptable tolerance. Always pre-drill or bore the hole to the appropriate undersize before reaming to prevent tool overload. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish quality.
