Value Collection 144429604990000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429604990000 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent performance in manual and CNC machine setups. The reamer measures 0.4990 inches in diameter, making it an undersize reamer suited for achieving tight dimensional control on finished bores. With an overall length of 8 inches and a flute length of 2 inches, this tool provides the reach and cutting engagement needed for standard through-hole and shallow blind-hole reaming operations. Installation and use are handled by machinists and toolroom professionals.

This chucking reamer is intended for machine-driven reaming operations where accurate bore sizing is required. The straight-cylindrical shank allows secure seating in standard drill chucks, collet holders, and floating reamer holders used on lathes, mills, and drill presses. The right-hand cutting direction suits conventional machine spindle rotation. As an undersize reamer designated 0.4990 U/S, it is appropriate for applications requiring a bore that falls slightly below nominal half-inch diameter, such as fitting dowel pins or precision shafts to close tolerances.

Key Features

• 0.4990 inch undersize diameter for precise bore control below nominal half-inch
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Straight flute geometry provides smooth cutting action and easy chip evacuation
• Bright, uncoated finish maintains dimensional accuracy without coating buildup
• Straight-cylindrical shank fits standard chucks and collet holders
• Right-hand cut compatible with conventional machine spindle rotation

Compatibility

Designed as an OEM-style machine reamer for use in standard drill chucks, collet holders, and floating reamer holders on lathes, drill presses, and milling machines where a straight-cylindrical shank is accepted.

Installation Notes

Chucking reamers are installed and operated by machinists or toolroom professionals. Secure the shank fully in a rigid holder or floating reamer holder to prevent runout. Always power down and de-energize the machine before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
