Value Collection 144429604365000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429604365000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise diameter of 0.4365 inches. Built with a straight flute geometry and a bright, uncoated surface, this reamer delivers consistent sizing in a wide range of workpiece materials. The straight-cylindrical shank seats securely in drill chucks and collet holders for reliable runout control. With an overall length of 7 inches and a flute length of 1-3/4 inches, it is sized for general-purpose machine reaming in both production and maintenance environments. It is classified as an under-size reamer at 0.4365 U/S, making it appropriate for applications requiring controlled interference or press-fit hole tolerances.

This reamer is suited for machine shop, tool room, and maintenance operations where hole size and surface finish are critical. It is used in CNC machining centers, knee mills, drill presses, and manual lathes running right-hand cutting direction. The under-size designation makes it a practical choice when a subsequent finishing operation or press fit is required. Machinists and tool and die professionals working in metal fabrication, general manufacturing, and MRO environments will find this a direct-fit solution for reaming holes in the 0.4000 to 0.4999 inch diameter range.

Key Features

• Reamer diameter of 0.4365 inches with under-size designation (0.4365 U/S) for controlled-fit applications
• High-speed steel (HSS) construction for durability across a broad range of ferrous and non-ferrous materials
• Straight flute design for smooth cutting action and easy chip evacuation in through-holes
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank for compatibility with standard drill chucks and collet holders
• Right-hand cutting direction for conventional machine reaming setups

Compatibility

Designed for use in standard drill chucks and collet holders accepting straight-cylindrical shanks; suitable for machine reaming applications requiring a nominal hole diameter in the 0.4000 to 0.4999 inch decimal inch range.

Installation Notes

Chucking reamers are installed and operated by machinists using machine tools such as drill presses, mills, or lathes. Always secure the shank fully in the chuck or collet and verify runout before cutting. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never hand-rotate a machine reamer in a chuck to back it out of a hole, as this can dull the cutting edges.
