Value Collection 144429600004000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429600004000 is a straight-flute chucking reamer machined from high-speed steel (HSS) and designed to bring bored or drilled holes to a precise finished diameter. Built for use in machine tools such as drill presses, lathes, and CNC machining centers, this reamer produces accurate, smooth-walled holes in ferrous and non-ferrous metals. It carries a wire size 4 designation, corresponding to a decimal diameter of 0.2090 inches, and features a straight-cylindrical shank for secure chuck retention. The bright, uncoated finish is standard for general-purpose HSS reamers running at moderate speeds with appropriate cutting fluid.

This chucking reamer is suited for production and maintenance machine shops, toolrooms, and job shops working with close-tolerance hole finishing. It is appropriate for use in manual lathes, turret lathes, drill presses, and CNC turning or machining centers where a straight-flute, right-hand-cut reamer is specified. Typical applications include finishing clearance holes and pin holes to wire-gauge tolerances in mild steel, aluminum, brass, and similar workpiece materials.

Key Features

• Wire size 4 diameter: 0.2090 inches, within the 0.2000 to 0.2499 inch decimal range
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• Straight flute geometry suited for through-holes and short blind holes
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collet holders without modification
• Bright, uncoated finish for general-purpose use with cutting fluid

Compatibility

Designed as a general-purpose chucking reamer for use in any machine tool equipped with a standard drill chuck or collet capable of holding a straight-cylindrical shank at the specified diameter.

Installation Notes

Chucking reamers are installed and operated by machinists in machine shop environments. Secure the straight-cylindrical shank firmly in a drill chuck or collet before operation, and confirm the spindle is fully stopped before making any tool changes. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish. Do not use a chucking reamer to remove excessive stock; pre-drill or bore the hole to within a few thousandths of final size before reaming.
