Value Collection 144429605050000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429605050000 is a chucking reamer designed for precision hole finishing in metalworking applications. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer features a straight-cylindrical shank for secure chuck mounting and an 8-flute straight flute configuration that delivers a smooth, accurate bore. The 0.5050-inch diameter makes it suited for finishing holes to close tolerances just above the nominal half-inch size. Right-hand cutting direction is standard for conventional drill press and lathe reaming operations. Machinists and tool-and-die professionals rely on this style of reamer when a clean, consistent finish is required after drilling.

This chucking reamer is used in machine shop environments where a drilled hole must be brought to a precise final diameter. It is appropriate for use in drill presses, lathes, and CNC machining centers capable of holding a straight-cylindrical shank. Typical applications include finishing bearing bores, pin holes, and close-tolerance locating holes in ferrous and non-ferrous metals. The 0.5050-inch diameter falls within the 0.5000 to 0.6999-inch decimal inch reamer range.

Key Features

• 0.5050-inch finished bore diameter for close-tolerance hole finishing just above nominal 1/2 inch
• HSS construction provides hardness and wear resistance for general-purpose metal reaming
• 8-flute straight flute geometry promotes smooth cutting action and consistent surface finish
• Right-hand cutting direction compatible with standard spindle rotation
• Straight-cylindrical shank seats securely in drill chucks and collets
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy

Compatibility

Designed as a standard chucking reamer for use in any machine tool capable of accepting a straight-cylindrical shank, including drill presses, engine lathes, and machining centers. Suitable for finishing holes in ferrous and non-ferrous workpiece materials.

Installation Notes

Chucking reamers are installed by machinists using a drill chuck or collet holder; ensure the shank is fully seated and the chuck is properly tightened before operation. Always reduce spindle speed relative to drilling and use appropriate cutting fluid to extend tool life and improve surface finish. Never force a reamer through an undersized hole — the pilot bore should be drilled close to the reamer diameter, leaving only a small amount of stock for the reaming pass.
