Value Collection 144429604950000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429604950000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.4950-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers clean, accurate bores in a wide range of ferrous and non-ferrous metals. The straight-cylindrical shank seats securely in standard drill chucks and collets, making it a practical choice for lathe, drill press, and machining center setups. Eight flutes provide a smooth cutting action and help evacuate chips efficiently during the reaming pass. This tool is intended for use by machinists, tool-and-die makers, and maintenance professionals who require close-tolerance hole finishing.

This chucking reamer is suited for general-purpose hole finishing operations in machine shops, maintenance facilities, and production environments. It is appropriate for both manual machine operation and CNC applications where a straight-cylindrical shank is accepted by the spindle or chuck assembly. Typical applications include sizing holes for press fits, slip fits, and precision bearing bores in ferrous alloys, aluminum, and similar machinable materials. The 0.4950-inch diameter falls within the 0.4000 to 0.4999 inch reamer diameter range category.

Key Features

• 0.4950-inch finished bore diameter for precise hole sizing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• 8-flute straight configuration for smooth cutting action and efficient chip evacuation
• Bright, uncoated finish suitable for general-purpose reaming operations
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Right-hand cutting direction for conventional reaming setups

Compatibility

Designed as a general-purpose chucking reamer for use in standard drill chucks, collets, and spindle holders that accept a straight-cylindrical shank. Suitable for lathes, drill presses, and machining centers configured for right-hand cut tooling.

Installation Notes

A qualified machinist should install and operate this reamer. Ensure the machine spindle and workpiece are secure before beginning the reaming pass, and confirm the chuck or collet is tightened to the appropriate holding force for the shank diameter. Always ream at reduced RPM compared to drilling, using a cutting fluid appropriate for the workpiece material to extend tool life and improve finish quality. Never use a reamer to remove excessive stock — pre-drill or bore the hole to within 0.005 to 0.015 inches of finished size before reaming.
