Value Collection 144429602030000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602030000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.2030-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers clean, accurate results in ferrous and non-ferrous materials. The straight-cylindrical shank is compatible with standard drill chucks and collet holders, allowing direct mounting in a drill press, milling machine, or CNC machining center. Six straight flutes provide a smooth cutting action with right-hand rotation. At 0.06 pounds, the tool is lightweight and easy to handle during setup.

This reamer is suited for machine shop, maintenance, and production applications where hole tolerances require finishing beyond what a drill bit alone can achieve. It is commonly used in metalworking operations to bring through-holes or blind holes to close-tolerance dimensions. Typical applications include bearing seat preparation, dowel pin hole finishing, and precision fixture work in both job-shop and light manufacturing environments. The 0.2030-inch diameter falls within the 0.2000 to 0.2499 decimal-inch reamer range.

Key Features

• 0.2030-inch finished hole diameter with HSS construction for durability across a range of workpiece materials
• Six straight flutes provide smooth, consistent material removal and accurate hole geometry
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collet systems without adapters
• Bright uncoated finish suitable for general-purpose reaming applications
• Lightweight at 0.06 pounds for easy handling and tool-changer compatibility

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, milling machines, lathes, and CNC machining centers equipped with standard drill chucks or collet holders accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed by a machinist or toolroom technician. Secure the straight-cylindrical shank firmly in a drill chuck or collet before use, and verify runout is within acceptable limits for the tolerance required. Always reduce spindle speed compared to drilling the same diameter, and apply cutting fluid appropriate for the workpiece material to extend tool life and improve finish. Never force a reamer through an undersized hole — ensure the pre-drilled or bored hole is within the recommended stock allowance for the reamer diameter before engaging the tool.
