Value Collection 144429602400000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602400000 is a straight-flute chucking reamer designed for precision hole finishing in metal workpieces. Built from high speed steel (HSS) with a bright polished finish, it delivers accurate sizing and smooth surface finishes in a wide range of ferrous and non-ferrous materials. The reamer measures 0.397 inches in diameter with a 7-inch overall length and a 1-3/4-inch flute length. The straight shank is compatible with standard drill chucks and collet holders. Right-hand cutting direction suits conventional CNC and manual machining setups. Machinists and tool and die professionals reach for this reamer when hole tolerances demand more than a drill bit alone can provide.

This chucking reamer is suited for general-purpose reaming operations in job shop, production, and maintenance environments. It is used to bring drilled or bored holes to a precise finished diameter in materials such as mild steel, aluminum, brass, and cast iron. The 0.397-inch diameter corresponds to letter size X, placing it in the 0.3500 to 0.3999 inch decimal range. It is typically run in a drill press, lathe tailstock, or CNC machining center at reduced speeds and with appropriate cutting fluid for optimal results.

Key Features

• High speed steel construction for durability across a broad range of workpiece materials
• Bright polished finish reduces friction and aids chip evacuation
• 0.397-inch (letter X) diameter for precision hole finishing in the 0.3500 to 0.3999 inch range
• Straight flute geometry suited for through-holes and most standard reaming applications
• 7-inch overall length with 1-3/4-inch flute length provides adequate reach for typical workpiece depths
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as a general-purpose chucking reamer compatible with drill chucks, collet systems, and toolholders accepting a straight shank configuration on drill presses, lathes, and machining centers.

Installation Notes

Chucking reamers are installed and operated by machinists familiar with speeds, feeds, and cutting fluid requirements for the workpiece material. Secure the straight shank firmly in a chuck or collet before operation, and verify there is no runout before engaging the workpiece. Always reduce spindle speed relative to drilling and apply a suitable cutting fluid to extend tool life and improve finish quality. Pre-drill or bore the hole to the appropriate undersized diameter before reaming.
