Value Collection 144429610140000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429610140000 is a straight-flute chucking reamer designed for precision hole finishing in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing in a range of drilling and boring applications. The reamer measures 1.250 inches in diameter and carries an overall length of 11.5 inches, with a 3-inch flute length that provides sufficient cutting surface for through-hole and blind-hole work. The straight-cylindrical shank seats securely in standard drill chucks and machine tool holders. Right-hand cutting direction is standard for conventional machine operation. Machinists and tool-and-die professionals install this reamer when a drilled or bored hole requires a tight-tolerance, smooth-finish final pass.

This chucking reamer is suited for use in drill presses, lathes, CNC machining centers, and manual milling machines where accurate hole sizing is required. The 1-1/4-inch diameter is a common specification in production and repair environments dealing with larger bores, bushings, and precision-fit assemblies. Its HSS construction holds an edge well across a range of ferrous and non-ferrous materials under normal cutting speeds. The straight flute design works reliably in materials that do not require chip-breaking geometry.

Key Features

• 1.250-inch reamer diameter for precision final-pass hole sizing
• High-speed steel (HSS) construction for edge retention across ferrous and non-ferrous materials
• Bright, uncoated finish — no added coating to affect dimensional tolerance
• 3-inch straight flute length for consistent chip clearance during the cut
• 11.5-inch overall length for reach in deeper setups
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cutting direction for use with conventional machine rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers equipped with a drill chuck or collet system capable of holding a straight-cylindrical shank at 1-1/4-inch diameter.

Installation Notes

Chucking reamers are installed and operated by machinists following standard machine shop practices. Power down the machine and confirm the spindle is fully stopped before mounting or removing the reamer. Seat the straight-cylindrical shank fully into the chuck or collet and tighten securely to prevent runout. Use appropriate cutting fluid for the workpiece material, and never exceed recommended feed rates for HSS tooling, as excessive feed pressure will damage the cutting edges.
