Value Collection 144429603900000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603900000 is a straight-flute chucking reamer designed to finish-size drilled or bored holes to a precise 0.3900-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate, repeatable hole sizing in a wide range of metals and engineering materials. The straight-cylindrical shank mounts directly into standard drill chucks, collet chucks, or floating holders. With six flutes and a right-hand cutting direction, it removes material evenly and leaves a clean, smooth bore wall. It weighs 1.79 pounds and is packaged individually.

This chucking reamer is suited for machine shop, maintenance, and production environments where hole tolerances demand more than a drill alone can achieve. Typical applications include reaming through-holes and blind holes in ferrous and non-ferrous workpieces on drill presses, lathes, and milling machines. It falls within the 0.3500 to 0.3999 inch reamer diameter range and is an appropriate choice for jobbing and tool-room use where an uncoated HSS reamer meets the material and speed requirements of the job.

Key Features

• 0.3900-inch reamer diameter for precise hole finishing
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• Six straight flutes for even material removal and smooth bore finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Bright, uncoated finish — no coating to add dimensional variation at the cutting edge

Compatibility

Designed as an OEM-style replacement and standard tooling option for machine tool setups requiring a straight-shank chucking reamer in the 0.3500 to 0.3999 inch diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists and tool-room technicians. Secure the straight-cylindrical shank firmly in a drill chuck, collet chuck, or floating reamer holder before use. Always ensure the machine spindle is fully stopped and locked out before changing or adjusting the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish — running an HSS reamer dry on steel will shorten its service life significantly.
