Value Collection 144429606420000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429606420000 is a straight-flute chucking reamer designed to finish-size drilled or bored holes to a precise 0.6420-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent dimensional accuracy in general machining applications. The straight-cylindrical shank seats securely in standard drill chucks or collet holders, and the 8-flute geometry distributes cutting load evenly for smooth, accurate bore finishing. At 0.5 pounds, it is a standard bench-stock tool well suited to machine shops and maintenance environments.

This chucking reamer is intended for use in drill presses, lathes, and milling machines where a drilled hole requires finishing to a close-tolerance 0.6420-inch diameter. It falls within the 0.5000-to-0.6999-inch reamer diameter range, covering a broad class of medium-bore finishing work. Typical applications include reaming bearing bores, bushing seats, and precision-fit pin holes in ferrous and non-ferrous materials. It is not configured as an over/under size reamer, nor as a dowel pin reamer, making it a general-purpose straight finishing tool.

Key Features

• 0.6420-inch finished bore diameter for precise hole sizing
• 8-flute straight design distributes cutting forces and produces a clean surface finish
• HSS construction provides durability across a broad range of workpiece materials
• Bright uncoated finish suitable for use with standard cutting fluids
• Right-hand cutting direction compatible with conventional machine spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collet holders without adapters

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and milling machines accepting a straight-cylindrical shank tool in the 0.5000-to-0.6999-inch diameter class.

Installation Notes

Chucking reamers are installed and operated by machinists familiar with machine shop practice. Secure the straight-cylindrical shank firmly in a drill chuck or collet before use, and verify runout is within acceptable limits before beginning the cut. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Power down and lock out the machine spindle before changing or inspecting the tool.
