Value Collection SM0406780 Chucking Reamer 0.6780 in Hss

Product Description

The VALUE COLLECTION SM0406780 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it machines a nominal diameter of 0.6780 inches with a 9-inch overall length and a 2.25-inch flute length. The straight-cylindrical shank seats securely in standard drill press or lathe chucks. Six right-hand flutes deliver smooth cutting action and clean bore walls in a single pass. This reamer is sized within the 0.5000 to 0.6999-inch diameter range, making it a practical tool for production and maintenance machining where close tolerances are required.

This chucking reamer is suited for general-purpose reaming operations in machine shops, maintenance facilities, and production environments. It is used to bring drilled or bored holes to precise finished dimensions in ferrous and non-ferrous metals. The straight-cylindrical shank makes it compatible with standard chucking setups on drill presses, lathes, and milling machines. Machinists and tool-and-die professionals reach for this style of reamer when dimensional accuracy and surface finish inside a bore are critical to fit and function.

Key Features

• 0.6780-inch finished bore diameter for tight-tolerance hole sizing
• High-speed steel (HSS) construction provides durability across a range of workpiece materials
• Six straight flutes with right-hand cutting direction for smooth, consistent material removal
• Bright, uncoated finish suitable for general-purpose machining without added coating cost
• Straight-cylindrical shank for direct chucking in drill press, lathe, or mill setups
• 9-inch overall length provides reach for deeper setups while maintaining rigidity

Compatibility

Designed as a general-purpose chucking reamer compatible with standard drill press chucks, lathe tailstock chucks, and milling machine setups that accept a straight-cylindrical shank within the 0.5000 to 0.6999-inch diameter class.

Installation Notes

Secure the straight-cylindrical shank firmly in the chuck before operation and verify runout with a dial indicator when close tolerances are required. Always use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Ensure the workpiece is clamped securely and the machine spindle speed is set to a value appropriate for the workpiece material and reamer diameter before beginning the cut. Inspect flutes for wear or chipping before each use and do not force the reamer through an undersized bore.
