Value Collection 144429603830000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603830000 is a straight-flute chucking reamer designed to finish-ream drilled holes to a precise 0.3830-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent bore sizing in a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats directly in a drill chuck or collet, making it practical for use in drill presses, lathes, and CNC machining centers. With six flutes and a right-hand cutting direction, it produces a smooth finish and accurate hole geometry for close-tolerance work. Machinists, tool-and-die makers, and maintenance technicians reach for this type of reamer when a drilled hole needs to meet a specific finished diameter.

This chucking reamer is suited for general machining applications requiring controlled hole sizing in the 0.3500 to 0.3999-inch diameter range. Typical use cases include reaming bearing bores, bushing seats, and precision-fit pin holes in production and maintenance environments. The straight flute geometry makes it appropriate for through-holes and most standard reaming operations where chip ejection is not a limiting factor. It is sold individually and is a direct grab-and-go option for shops that need a replacement or supplemental reamer in this size range.

Key Features

• 0.3830-inch finished diameter for close-tolerance hole sizing
• Six straight flutes with right-hand cut for smooth bore finish
• High-speed steel (HSS) construction handles a broad range of workpiece materials
• Bright, uncoated finish — no coating to account for in tolerance stack-up
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Not an over/under size reamer — cuts to nominal 0.3830-inch diameter

Compatibility

Designed as a standard chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a drill chuck or straight-shank collet in the appropriate size range.

Installation Notes

A licensed machinist or experienced technician should confirm spindle alignment and workholding rigidity before reaming, as misalignment causes bell-mouthing and oversize bores. Always ream from a previously drilled or bored hole that leaves only a small amount of material for the reamer to remove. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never run a reamer in reverse, as this dulls the cutting edges rapidly.
