Value Collection 144429604020000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429604020000 is a straight-flute chucking reamer designed for precision hole finishing in metal workpieces. Built from high-speed steel (HSS), it delivers the hardness and wear resistance needed for consistent sizing in production and maintenance applications. The 0.4020-inch diameter and 6-flute geometry produce a smooth, accurate bore with minimal chatter. The straight-cylindrical shank allows secure seating in standard drill chucks and collet holders on lathes, drill presses, and milling machines. Machinists and toolroom technicians use this type of reamer as the final step after drilling to bring a hole to tight dimensional tolerance.

This chucking reamer is suited for general metalworking applications where a 0.4020-inch finished bore is required. Typical uses include reaming clearance holes for precision pins, bushings, and close-tolerance fasteners in both job-shop and production settings. Its straight-cylindrical shank makes it compatible with a wide range of machine tool spindles without the need for specialty toolholders. The HSS construction handles most ferrous and non-ferrous materials at standard cutting speeds.

Key Features

• 0.4020-inch finished bore diameter for precision hole sizing
• High-speed steel (HSS) construction for hardness and wear resistance
• 6-flute straight geometry for smooth surface finish and stable cutting action
• Straight-cylindrical shank seats securely in standard drill chucks and collet holders
• Standard chucking reamer design suitable for lathe, drill press, and milling machine use

Compatibility

Designed as a standard chucking reamer for use in any machine tool spindle accepting a straight-cylindrical shank of appropriate diameter, including drill chucks and collet holders commonly found on lathes, drill presses, and knee mills.

Installation Notes

Chucking reamers are installed by licensed machinists or qualified toolroom personnel. Before mounting, ensure the machine spindle is fully stopped and locked out per applicable safety procedures. Secure the straight-cylindrical shank firmly in a true-running chuck or collet to minimize runout, which directly affects finished hole accuracy. Apply appropriate cutting fluid for the workpiece material and avoid excessive feed rates that can load the flutes or reduce tool life.
