Value Collection 144429601000000 Chucking Reamer Letter J

Product Description

The VALUE COLLECTION 144429601000000 is a Letter J chucking reamer machined from high-speed steel (HSS) for reaming drilled holes to precise finished dimensions. It features a straight flute geometry and a straight-cylindrical shank, making it compatible with standard drill chucks and collet holders. The cutting diameter is 0.2770 inches, placing it within the 0.2500 to 0.2999 inch decimal range for Letter J sizing. Overall length is 6 inches with a 1.5-inch flute length. Right-hand cutting direction and a bright, uncoated finish round out the core construction. Machinists and tool-and-die professionals use this reamer for light stock removal to achieve tight bore tolerances in metal workpieces.

This chucking reamer is suited for general metalworking applications including fixture and jig making, component hole finishing, and production machining where a Letter J hole is required. The straight-cylindrical shank seats directly in a drill press, lathe tailstock, or milling machine spindle chuck. The HSS construction handles a broad range of common workpiece materials including mild steel, aluminum, brass, and cast iron at standard cutting speeds.

Key Features

• Letter J diameter: 0.2770 inches decimal equivalent for precise finished bore sizing
• High-speed steel (HSS) construction provides durability across common metalworking materials
• Straight flute design allows straightforward chip evacuation in through-hole applications
• Straight-cylindrical shank seats in standard drill chucks and collet holders without adapters
• Right-hand cutting direction compatible with conventional machine spindle rotation
• Bright, uncoated finish suited for use with cutting fluids on a variety of workpiece materials

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 the 0.2770-inch diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists following standard machine shop practices. Power down and lock out the machine spindle before mounting or removing the reamer from the chuck or collet. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Allow the drill hole to be sized correctly before reaming, leaving only the minimal recommended stock for the reamer to remove, as reamers are not designed for heavy material removal.
