• Precise Concentricity for Second Operations:
This expanding arbor set is specially designed to hold workpieces by their internal diameter (ID) during machining. It ensures excellent concentricity and parallel alignment, which is often difficult to achieve with standard chucks.
• Comprehensive 8-Piece Set:
The set includes 8 expanding arbors ranging from 1/4" to 1-1/4" in 1/8" increments:
1/4", 3/8", 1/2", 5/8", 3/4", 7/8", 1", and 1-1/4".
This wide range provides a practical solution for most common bore sizes used in machining applications.
• Innovative Expandable Design:
Each arbor features a hex screw expansion mechanism. When tightened, the arbor expands slightly to securely grip the workpiece from the inside, making it ideal for thin-walled tubes, rings, and delicate components without causing deformation.
• Laser-Marked for Quick Setup:
Every arbor is laser-etched with its size, allowing machinists to quickly identify the correct tool. This helps reduce setup time and prevents selection errors in busy workshop environments.
• Versatile Mounting Options:
These arbors can be easily clamped in a lathe chuck, collet system (such as 5C or R8), or milling fixtures. The straight shank design ensures compatibility with a wide variety of tool-holding systems.
• Organized Wooden Storage:
The complete set comes with a premium wooden storage stand, keeping the tools organized and protected while preventing scratches or damage to the precision-ground surfaces.
