A rotary tool holder bushing with a type J design, 1/4 inside diameter (ID), 1 outside diameter (OD), and 1-3/4 length under head is commonly used in machining operations to hold rotary tools such as end mills or drills onto a spindle. Its size and material make it suitable for use on standard size toolholder shanks, offering compatibility with various machine tools and chucks. The type J design allows for better grip and less wear on the tool holder, resulting in improved accuracy and longer lifespan. The steel construction ensures durability and resistance to wear, while the size and length provide a secure fit without causing damage to the workpiece. This rotary tool holder bushing is an essential component in the precision machining industry, enabling users to create accurate and consistent parts with minimal effort.
