Rotary Tool Holder Bushing: Type J, 1-1/4" ID, 1-3/4" OD, 3" Length Under Head MPN:8604J 1.250

A rotary tool holder bushing with a type J design, 1-1/4 inside diameter (ID), 1-3/4 outside diameter (OD), and 3 length under head serves as an essential component in precision machining operations to securely hold end mills or drills onto spindles. The Type J bushing accommodates various machine tools, chucks, and toolholders while offering increased rigidity and better grip on the rotary tool, resulting in improved accuracy and longevity of the cutting edge. The length and dimensions ensure a perfect fit, reducing the risk of damage to both the workpiece and the tool holder bushing. Due to its precise tolerances and versatile application, this component is widely used across industries such as automotive, medical, electronics, and aerospace, streamlining manufacturing processes and reducing errors in production.
