Value Collection 144429604390000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429604390000 is a straight-flute chucking reamer designed for precision hole finishing in machine shop and production environments. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent bore sizing at a nominal diameter of 0.4390 inches. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. With 8 flutes and a right-hand cutting direction, it produces smooth, accurate holes in a wide range of workpiece materials. Machinists and toolroom technicians rely on this style of reamer for final-pass sizing after drilling or boring operations.

This chucking reamer is suited for use in drill presses, lathes, CNC machining centers, and manual milling machines. It is appropriate for general metalworking applications where a finished bore within the 0.4000 to 0.4999 inch decimal range is required. The straight-cylindrical shank makes it compatible with a broad selection of standard machine tool holders, reducing the need for specialty adapters in typical shop setups.

Key Features

• 0.4390 inch nominal reamer diameter for precise hole finishing
• High-speed steel (HSS) construction for durability across common metal workpieces
• 8-flute straight flute geometry for smooth surface finish and chip clearance
• Right-hand cutting direction for standard machine rotation
• Straight-cylindrical shank compatible with most drill chucks and collet holders
• Bright, uncoated finish — no special handling required for most metalworking applications

Compatibility

Designed as a general-purpose chucking reamer for machine tool applications requiring a finished bore in the 0.4000 to 0.4999 inch decimal inch range with a straight-cylindrical shank interface.

Installation Notes

Chucking reamers are installed by qualified machinists using standard drill chucks or collet holders rated for the shank diameter. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer. Run at recommended speeds and feeds for the workpiece material — excessive feed rate is the most common cause of premature wear or oversized bores. Always pre-drill or bore the hole close to final size before reaming to achieve proper finish and diameter tolerance.
