Value Collection 144429601390000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429601390000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.1390-inch diameter. Built with a straight-cylindrical shank for secure chuck mounting, this reamer features six straight flutes and a right-hand cutting direction, producing clean, accurate bores with consistent surface finish. The bright, uncoated HSS construction provides reliable performance across a range of common work materials. Machinists and tool-and-die professionals reach for this style of reamer when a drilled hole needs to be brought to final tolerance with minimal runout and controlled material removal.

This chucking reamer is suited for use in drill presses, lathes, and milling machines in both production shop and job-shop environments. The 0.1390-inch diameter falls within the 0.1000- to 0.1499-inch decimal inch range, making it appropriate for small-bore finishing operations in metal fabrication, maintenance repair, and precision machining applications. It is sold individually and is compatible with standard three-jaw and collet chucks that accept a straight-cylindrical shank.

Key Features

• 0.1390-inch finished bore diameter for precise hole sizing
• High-speed steel (HSS) construction for durability across common metals
• Six straight flutes for smooth, consistent material removal
• Right-hand cutting direction for standard machine operation
• Straight-cylindrical shank for universal chuck compatibility
• Bright, uncoated finish — no coating buildup to affect diameter tolerance

Compatibility

Designed as an OEM-style replacement and standard chucking reamer for use with any drill press, lathe, or milling machine equipped with a chuck or collet that accepts a straight-cylindrical shank in the corresponding size range.

Installation Notes

Chucking reamers are installed and operated by machinists in machine shop environments. Before mounting, ensure the spindle is fully stopped and the chuck is clean and free of debris to prevent runout. Run the reamer at lower RPM than drilling and use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish. Do not attempt to remove excessive stock with a reamer — pre-drill or bore the hole to within a few thousandths of final diameter before reaming.
