Value Collection 144429602764000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602764000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise diameter. Built from high-speed steel (HSS), it delivers the hardness and edge retention needed for accurate sizing in ferrous and non-ferrous metals. The reamer measures 0.4219 inches (27/64 inch) in diameter, with a 7-inch overall length and a 1-3/4-inch flute length. The straight-cylindrical shank mounts directly into a drill chuck, collet, or reaming fixture on a drill press, lathe, or CNC machining center. Machinists, tool-and-die workers, and maintenance technicians use this tool to bring a rough-drilled hole to final size with a clean, smooth finish wall.

This reamer is suited for production and maintenance machining applications where consistent hole sizing is required. It is appropriate for use in manual drill presses, engine lathes, and light CNC equipment. The straight-flute geometry is best suited for through-holes and shorter blind holes in materials that produce broken chips. Typical applications include bearing bores, bushing installations, pin fits, and any precision hole where a tight dimensional tolerance is required after drilling.

Key Features

• 27/64 inch (0.4219 inch) reamer diameter for precise hole sizing
• High-speed steel (HSS) construction for hardness and edge retention in metal cutting
• Straight-flute design suited for through-holes and short blind holes
• Straight-cylindrical shank compatible with standard drill chucks and collets
• 7-inch overall length provides reach for a range of workpiece setups
• 1-3/4-inch flute length handles typical production reaming depths

Compatibility

Designed as a standard-size chucking reamer for use in drill presses, lathes, and machining centers equipped with a drill chuck or collet that accepts a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed by machinists and maintenance technicians using standard drill chucks or collets rated for the shank diameter. Power down and lock out all machine energy before mounting or removing the tool. Use a cutting fluid or lubricant appropriate for the workpiece material to extend tool life and improve hole finish. Always ream after drilling to a recommended pre-ream diameter slightly smaller than the finished size; do not attempt to remove excessive stock with a reamer alone.
