Value Collection 144429604380000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429604380000 is a chucking reamer designed to finish-ream precision holes to a nominal diameter of 0.4380 inches. Constructed from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent bore accuracy in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. With 8 straight flutes and a right-hand cutting direction, it produces smooth, accurate bores suitable for close-tolerance work in machining, toolroom, and maintenance applications. Licensed tradespeople and machinists use this style of reamer as a finishing step after drilling to bring a hole to final size and surface finish.

This chucking reamer is suited for use on drill presses, lathes, and milling machines in machine shops, maintenance facilities, and production environments. It is appropriate for general-purpose reaming operations where a bright HSS tool meets the hardness and finish requirements of the workpiece material. The straight flute geometry makes it particularly effective in softer materials and through-hole applications where chip evacuation is straightforward.

Key Features

• 0.4380 inch finished bore diameter for close-tolerance hole sizing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• 8 straight flutes for smooth cutting action and consistent surface finish
• Right-hand cutting direction compatible with standard machine rotation
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Bright, uncoated finish suitable for general-purpose reaming applications

Compatibility

Designed as an OEM-style replacement and general-purpose chucking reamer compatible with standard drill chucks and collet holders accepting a straight-cylindrical shank in the 0.4000 to 0.4999 inch diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists using drill presses, lathes, or milling machines. Always secure the shank fully in the chuck or collet before operation, and ensure the spindle speed and feed rate are appropriate for the workpiece material and reamer diameter — consult standard machining data references for recommended cutting parameters. Never use a reamer to remove excessive stock; pre-drill or bore the hole to within approximately 0.005 to 0.015 inches of final size before reaming. Proper cutting fluid or coolant application extends tool life and improves bore finish.
