Value Collection 144429604080000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429604080000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.4080-inch diameter. Straight flutes and a bright, uncoated finish make this reamer well suited for controlled-feed sizing operations in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in a drill chuck or collet on a drill press, lathe, or CNC machining center. Machinists, tool-and-die technicians, and maintenance professionals use chucking reamers where tight hole tolerances and smooth bore finish are required.

This reamer is appropriate for general-purpose machine reaming in job shops, production environments, and maintenance applications. With a 0.4080-inch finished diameter, it falls within the 0.4000-to-0.4999-inch decimal inch range and is a standard choice when a close-tolerance through-hole or blind hole must be brought to final size after drilling. It is sold individually and is not an over-size or under-size specialty reamer, nor a dowel-pin reamer.

Key Features

• 0.4080-inch finished reaming diameter for precise hole sizing
• High-speed steel (HSS) construction provides good wear resistance across a range of workpiece materials
• 8 straight flutes deliver smooth cutting action and even chip evacuation
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits drill chucks and collets without an adapter
• Bright, uncoated finish — no coating to add or subtract from the ground diameter

Compatibility

Designed as a general-purpose machine chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank in the 0.4080-inch diameter class.

Installation Notes

A licensed machinist or qualified shop technician should secure the workpiece and verify spindle alignment before reaming. Power down and de-energize the machine before mounting or removing the reamer from the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve the desired bore finish. Never reverse spindle direction while the reamer is engaged in the hole, as this can damage the cutting edges.
