Value Collection 144429604730000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429604730000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.4730-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent dimensional accuracy in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in a drill chuck, collet chuck, or CNC toolholder, making it compatible with drill presses, lathes, and machining centers. Eight flutes provide a smooth, high-quality bore finish while distributing cutting load evenly across the tool. Right-hand cutting direction is standard for conventional clockwise spindle rotation.

This chucking reamer suits machine shop, maintenance, and production environments where hole tolerances require a finishing pass after drilling. Typical applications include reaming bearing bores, bushing fits, pin holes, and close-tolerance through-holes in steel, cast iron, aluminum, brass, and plastics. It is intended for use by machinists, toolmakers, and maintenance technicians working on manual or CNC machine tools. The 0.4730-inch diameter falls within the 0.4000 to 0.4999-inch range, making it a standard selection for fractional and decimal-inch hole finishing work.

Key Features

• 0.4730-inch finished bore diameter for close-tolerance hole sizing
• HSS construction provides good wear resistance and toughness across a wide range of workpiece materials
• 8-flute geometry distributes cutting forces for a smooth bore finish
• Right-hand cut, straight-flute design for use at conventional spindle speeds
• Straight-cylindrical shank fits standard drill chucks, ER collets, and CNC toolholders
• Bright, uncoated finish suitable for use with cutting oil or coolant

Compatibility

Designed as a standard machine chucking reamer compatible with drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a drill chuck or collet system sized to accept a straight-cylindrical shank in the 0.4730-inch diameter class.

Installation Notes

Chucking reamers must be run at significantly lower speeds than drills — typically one-third to one-half the drilling speed for the same material — with a consistent feed rate to avoid chatter and bell-mouthing. Always apply a suitable cutting fluid or coolant to extend tool life and improve surface finish. Pre-drill or bore the hole to within 0.005 to 0.015 inches of final size before reaming to ensure proper stock removal; do not attempt to use this reamer as a primary hole-making tool. Secure the shank fully in the toolholder and confirm runout is within acceptable limits before commencing the cut.
