Value Collection 144429602485000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602485000 is a chucking reamer designed for precision hole finishing in metal fabrication and machining applications. Built from high-speed steel (HSS), it features a 6-flute straight configuration and a straight-cylindrical shank for secure chuck mounting. With a reamer diameter of 0.2485 inches, this tool is used to bring drilled or bored holes to tight dimensional tolerances. The HSS construction provides good wear resistance and heat tolerance across a range of workpiece materials. Machinists and tool-and-die technicians rely on chucking reamers like this one to achieve consistent surface finish and accurate final hole diameter in production and repair settings.

This reamer is suited for use in drill presses, CNC machining centers, lathes, and manual milling setups where straight-hole finishing is required. The straight-cylindrical shank fits standard drill chucks and collet systems without modification. It is appropriate for finishing holes in mild steel, aluminum, brass, and similar machinable materials. With a diameter in the 0.2000 to 0.2499 inch range, it targets close-tolerance holes commonly found in fixture work, bearing fits, and precision assembly.

Key Features

• 0.2485 inch reamer diameter for close-tolerance hole finishing
• High-speed steel (HSS) construction for wear resistance and heat tolerance
• 6-flute straight configuration for smooth, consistent stock removal
• Straight-cylindrical shank fits standard drill chucks and collets
• Not configured as a dowel pin reamer or over/under size reamer

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers equipped with chuck or collet toolholding systems that accept straight-cylindrical shanks.

Installation Notes

Chucking reamers are installed by machinists using standard drill chucks or collet holders; confirm shank diameter fits the toolholder before use. Always ream at reduced spindle speed compared to drilling, and use an appropriate cutting fluid for the workpiece material to extend tool life and improve finish. Pre-drill or bore the hole to within a few thousandths of the final diameter before reaming. Inspect the reamer for nicks or wear before each use to avoid dimensional errors in the finished hole.
