Value Collection 144429600012000 Chucking Reamer 12 Hss

Product Description

The VALUE COLLECTION 144429600012000 is a straight-flute chucking reamer designed for precision hole finishing in metal and similar materials. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing performance on wire gauge 12 holes with a decimal diameter of 0.1890 inches. The straight-cylindrical shank allows secure seating in standard chucks and collets. With an overall length of 4.5 inches and a flute length of 1.125 inches, this reamer is suited for bench drilling, drill press, and CNC machine operations where tight bore tolerances are required. Machinists and tool-and-die technicians are the primary users.

This chucking reamer is used in machine shop environments for finishing drilled or bored holes to a precise wire gauge 12 diameter (0.1890 inches decimal). It is appropriate for general-purpose reaming in mild steels, aluminum, and similar machinable materials. The right-hand cutting direction is compatible with standard spindle rotation. Its compact flute length makes it suitable for shallow-depth hole finishing applications in both production and maintenance machining contexts.

Key Features

• Wire gauge 12 diameter, 0.1890 inches decimal for precise hole sizing
• High-speed steel (HSS) construction for durability across common machinable materials
• Straight flute geometry suited for through-hole and shallow blind-hole reaming
• Bright uncoated finish — no coating thickness to affect final bore diameter
• Straight-cylindrical shank for reliable chuck and collet grip
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as an OEM-style replacement or standard machine-shop chucking reamer for use in drill presses, lathes, or CNC machining centers equipped with chucks or collets accepting a straight-cylindrical shank.

Installation Notes

Installation is performed by machinists or toolroom technicians. Secure the straight-cylindrical shank fully in the chuck or collet before operation and confirm runout is within acceptable tolerance for the required bore finish. Power down the machine and lock out energy sources before changing or inspecting the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve the specified surface finish.
