Value Collection SM0406245 Chucking Reamer 0.6245 in Hss

Product Description

The VALUE COLLECTION SM0406245 is a straight-flute chucking reamer designed to finish-ream holes to a precise 0.6245-inch diameter in metalworking and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy with a tolerance of +0.0002 to -0.0000 inches. The six-flute geometry and right-hand cutting direction provide smooth chip evacuation and a clean bore finish. At 9 inches overall length with a 2.25-inch flute length and a straight-cylindrical shank, this reamer seats securely in standard drill chucks and collet systems. Machinists and tool-and-die technicians reach for this reamer when a drilled hole needs to be brought to a finished, close-tolerance dimension.

This chucking reamer is suited for general-purpose reaming on mills, drill presses, and lathes in job shops, maintenance, and production environments. It is appropriate for use in ferrous and non-ferrous metals where a straight-flute HSS tool performs reliably. The straight-cylindrical shank allows direct chucking without additional adapters in most standard setups. No dowel-pin or over/under-size geometry is present, making this a standard finish reamer for nominal-size hole preparation.

Key Features

• 0.6245-inch reamer diameter with a tolerance of +0.0002 to -0.0000 inches for close-tolerance bore finishing
• 6-flute straight-flute design for smooth cutting action and clean surface finish
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Bright, uncoated finish — ready to use out of the package
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank for direct chucking in drill chucks and collets

Compatibility

Designed as a standard finish chucking reamer for use in drill presses, milling machines, and lathes equipped with a drill chuck or collet capable of holding a straight-cylindrical shank in the 0.6245-inch diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists and tool-and-die technicians. Secure the straight-cylindrical shank firmly in a drill chuck or collet before operation and verify runout is within acceptable limits for the tolerance required. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Feed rate and spindle speed should follow established machining guidelines for HSS reamers in the given material — do not force the reamer or reverse-spin it while it remains in the bore.
