Value Collection SM0406980 Chucking Reamer Hss 0.6980 in

Product Description

The VALUE COLLECTION SM0406980 is a straight-flute chucking reamer designed for precision hole finishing in metal machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent bore sizing at a reamer diameter of 0.6980 inches. The straight-cylindrical shank seats securely in standard drill press or lathe chucks. With a 9-inch overall length and a 2.25-inch flute length, this six-flute reamer provides the cutting action needed to bring drilled or bored holes to a precise finished diameter. Right-hand cutting direction matches conventional machine rotation.

This chucking reamer is suited for machine shop use in drill presses, lathes, and milling machines where repeatable hole-finish quality is required. It is appropriate for production and maintenance machining on ferrous and non-ferrous metals where a 0.6980-inch finished bore is the target. Machinists and tool-and-die technicians typically select this reamer when a pre-drilled hole needs to be brought to final dimensional tolerance. The HSS construction handles moderate cutting speeds without requiring carbide tooling costs.

Key Features

• 0.6980-inch reamer diameter for precise finished bore sizing
• High-speed steel (HSS) construction withstands machining heat and wear
• Six straight flutes provide smooth, consistent stock removal
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank fits standard drill chucks and collets
• Right-hand cutting direction for use with conventional machine rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and milling machines equipped with a chuck or collet capable of accepting a straight-cylindrical shank at this diameter class.

Installation Notes

Chucking reamers are installed and operated by machinists or tool-and-die technicians. Secure the straight shank firmly in a drill chuck or collet before use, and ensure the machine spindle is fully stopped before changing tooling. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Pre-drill or bore the hole to within approximately 0.005 to 0.015 inches of final size before reaming to avoid overloading the flutes.
