Value Collection 144429604970000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429604970000 is a chucking reamer designed to finish-ream precision holes to a final diameter of 0.4970 inches. Constructed from high-speed steel (HSS) with a bright, uncoated finish, this tool delivers accurate sizing in a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks and collets. Eight straight flutes provide smooth cutting action with right-hand rotation. Licensed machinists, tool-and-die technicians, and maintenance professionals use chucking reamers like this one to bring drilled or bored holes to close-tolerance finished dimensions.

This reamer is suited for use in manual drill presses, CNC machining centers, lathes, and hand-held drilling equipment where a straight-cylindrical shank is compatible. It falls within the 0.4000 to 0.4999 inch diameter range and is appropriate for general-purpose reaming in production, job-shop, and maintenance-repair-overhaul settings. It is not configured as a dowel pin reamer or an over/under size reamer, making it a standard on-size tool for achieving nominal bore tolerances.

Key Features

• 0.4970 inch finished bore diameter for close-tolerance hole sizing
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• 8 straight flutes for consistent material removal and smooth finish
• Right-hand cutting direction compatible with standard machine rotation
• Straight-cylindrical shank for secure seating in drill chucks and collets
• Bright uncoated finish — ready to use without additional surface treatment

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers that accept a straight-cylindrical shank toolholder or collet in the appropriate size range.

Installation Notes

Chucking reamers are installed by machinists and toolroom technicians. Always ensure the workpiece and machine are properly secured before reaming. Run the reamer at reduced spindle speeds compared to drilling, with appropriate cutting fluid applied to extend tool life and improve surface finish. Never reverse a reamer under power, as this can damage the cutting edges and ruin the bore finish.
