Value Collection SM0406490 Chucking Reamer 0.6490 in Hss

Product Description

The VALUE COLLECTION SM0406490 is a straight-flute chucking reamer designed to bring holes to a precise finished diameter in machined components. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable cutting performance in a wide range of ferrous and non-ferrous workpiece materials. The reamer measures 0.6490 inches in diameter with a 9-inch overall length and a 2.25-inch flute length. Its straight-cylindrical shank seats directly in a drill chuck or collet, making it a straightforward tool for machine shops, maintenance facilities, and production environments where accurate hole sizing is required.

This chucking reamer is suited for finishing operations on drill press, lathe, or milling machine setups where a pre-drilled or bored hole needs to be brought to a close-tolerance final diameter. It is appropriate for general-purpose reaming in job shop and industrial maintenance applications. The 6-flute, right-hand cutting geometry provides smooth stock removal and good surface finish inside the bore. It is sold and packaged as a single unit.

Key Features

• 0.6490-inch finished bore diameter for close-tolerance hole sizing
• High-speed steel (HSS) construction for durability across common workpiece materials
• 6-flute straight-flute geometry for smooth cutting action and consistent surface finish
• Right-hand cutting direction compatible with standard machine rotation
• Bright uncoated finish suitable for use with cutting fluids in general machining
• Straight-cylindrical shank fits standard drill chucks and collets without adapters

Compatibility

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

Installation Notes

Chucking reamers are installed and operated by qualified machinists or maintenance technicians. Always secure the workpiece firmly and ensure the machine spindle is at a safe stopped position before mounting or removing the tool. Use an appropriate cutting fluid or lubricant for the workpiece material to extend tool life and improve surface finish. Never run a reamer in reverse, as this will damage the cutting edges.
