Value Collection 144429603210000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603210000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.3210-inch diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate sizing in a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank mounts securely in standard drill chucks, collets, or floating reamer holders. With 6 flutes and a right-hand cutting direction, it produces a smooth, consistent bore finish suitable for close-tolerance work in production and job-shop environments. It weighs 1.43 pounds.

This chucking reamer is suited for use on manual lathes, drill presses, machining centers, and CNC turning equipment where a reamed hole finish is required. It is appropriate for general metalworking applications including fixture fabrication, precision hole sizing, and dowel pin fitment preparation in both prototype and production runs. The 0.3210-inch diameter falls within the 0.3000 to 0.3499-inch reamer diameter range, making it a standard selection for that bore class.

Key Features

• 0.3210-inch finished bore diameter for precise hole sizing
• High-speed steel (HSS) construction for durability across common workpiece materials
• 6 straight flutes for consistent chip evacuation and smooth bore finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits standard drill chucks, collets, and floating holders
• Bright, uncoated finish — no added coating to affect dimensional tolerance

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers that accept a straight-cylindrical shank toolholder or drill chuck.

Installation Notes

Chucking reamers are installed and serviced by machinists and tool-and-die professionals. Before mounting, ensure the machine spindle is fully powered down and the chuck or collet is clean and free of debris. Always run reamers at reduced RPM and higher feed rates compared to drilling — running too fast without adequate cutting fluid accelerates wear and degrades bore finish. Use an appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy.
