Value Collection 144429604370000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429604370000 is a straight-flute chucking reamer machined from high-speed steel (HSS) for sizing and finishing drilled or bored holes to a precise 0.4370-inch diameter. The bright, uncoated finish is standard for general-purpose HSS reamers used in metalworking applications where no special surface treatment is required. With a 7-inch overall length and a 1.75-inch flute length, this reamer is sized for use in drill presses, lathes, and CNC machining centers. Right-hand cutting direction is standard. Machinists and tool-and-die professionals install this type of reamer when hole tolerances demand more precision than a twist drill can deliver.

This chucking reamer is suited for production and job-shop metalworking environments where holes must be brought to a close-tolerance finish diameter. The 0.4370-inch size corresponds to a dowel pin reamer application, making it a direct fit for preparing holes that will receive 0.4370-inch dowel pins in fixture, jig, and precision assembly work. The straight-cylindrical shank seats directly in drill chucks, collets, and standard machine tool holders without an adapter.

Key Features

• 0.4370-inch diameter matched to standard dowel pin sizing for precision hole finishing
• HSS construction provides durability across a range of ferrous and non-ferrous workpiece materials
• Straight flute geometry suits through-hole and shallow blind-hole reaming
• Right-hand cutting direction compatible with standard machine rotation
• Bright uncoated finish for general-purpose shop use
• Straight-cylindrical shank seats in drill chucks, collets, and ER-style toolholders

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by machinists following standard machine shop practices. Secure the shank firmly in a drill chuck or collet before use, and verify that runout is within acceptable limits to maintain hole accuracy. Always reduce spindle speed relative to the drilling operation and apply appropriate cutting fluid to extend tool life and improve surface finish. Never attempt to remove significant stock with a reamer; pre-drill or bore the hole to within a few thousandths of final diameter before reaming.
