Hertel 72020654 Chucking Reamer 0.2065 in Hss 6 Flute

Product Description

The HERTEL 72020654 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metalworking applications. With a reamer diameter of 0.2065 inches and an overall length of 5 inches, this tool delivers accurate, repeatable hole sizing in a compact, easy-to-chuck form factor. The straight flute geometry and bright uncoated finish make it well suited for reaming softer ferrous and non-ferrous metals where a smooth, polished bore is required. Machinists and tool-and-die professionals install this reamer in lathes, drill presses, and machining centers where tight dimensional tolerances are critical.

This reamer is used in production and maintenance machining environments for finishing drilled or bored holes to close tolerances. The 1.25-inch flute length provides adequate chip clearance for shallow to moderate-depth holes. The straight-cylindrical shank allows direct clamping in standard drill chucks or collet holders. Right-hand cutting direction is compatible with conventional machine spindle rotation. Typical applications include dowel hole finishing, bearing seat preparation, and precision fit reaming in both job-shop and production settings.

Key Features

• 0.2065-inch reamer diameter for precise hole sizing in the 0.2000 to 0.2499-inch diameter range
• HSS construction provides toughness and wear resistance for general-purpose metalworking
• 6-flute straight design delivers smooth surface finish and accurate roundness
• Right-hand cutting direction compatible with standard machine spindle rotation
• Bright uncoated finish — ready to use out of the box, with no coating to chip or flake
• Straight-cylindrical shank fits standard drill chucks and collet holders

Compatibility

Designed as an OEM-style replacement or direct substitute chucking reamer for use in standard drill chucks and collet-style toolholders on lathes, drill presses, and CNC machining centers requiring a 0.2065-inch finished bore diameter.

Installation Notes

Installation is performed by qualified machinists. Power down and lock out the machine before seating or removing the reamer from the chuck or collet. Ensure the shank is fully seated and the chuck or collet is tightened to the toolholder manufacturer's specification before running the spindle. Use appropriate cutting fluid for the workpiece material to maximize tool life and surface finish quality.
