Value Collection SM0406400 Chucking Reamer 0.6400 in Hss

Product Description

The VALUE COLLECTION SM0406400 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.6400-inch diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance across a broad range of ferrous and non-ferrous materials. The six-flute geometry distributes cutting load evenly, reducing chatter and improving hole finish. With a 9-inch overall length and a 2.25-inch flute length, this reamer suits standard machine spindle setups where controlled stock removal and tight dimensional tolerances are required.

This chucking reamer is used in machine shop and production environments where holes must be brought to a close-tolerance finish after drilling. The straight-cylindrical shank seats directly in a drill chuck, collet, or floating reamer holder on a drill press, mill, or lathe. Right-hand cutting direction makes it compatible with standard spindle rotation. Typical applications include reaming clearance holes, bearing bores, and locating pin holes in both prototype and production runs.

Key Features

• 0.6400-inch reamer diameter for precise, repeatable hole sizing
• HSS construction provides good wear resistance across a wide material range
• 6-flute straight configuration reduces chatter and improves surface finish
• Bright, uncoated finish suited for use with cutting fluid in general-purpose machining
• Straight-cylindrical shank fits standard drill chucks and collets without adapters
• Right-hand cutting direction compatible with conventional machine spindle rotation

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, milling machines, and lathes equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank in the 0.5000 to 0.6999-inch diameter range.

Installation Notes

Secure the shank firmly in a drill chuck, collet, or floating reamer holder before use. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish. Feed rate and spindle speed should be set conservatively compared to drilling operations to avoid bell-mouthing or oversize conditions. Inspect the reamer cutting edges for wear or chipping before each use and replace if damage is present.
