Hi-Lok Collar Removal Tools

Aircraft tools for the removal of threaded collars come in a variety of shapes and sizes to meet a wide range of needs in aviation. Some collar removal tools work best for aluminum collars, while others are well-suited for steel, titanium and aluminum. Space constraints often require the use of special configurations.

Collar removal tools from Omega Technologies offer a full range of aircraft tools for all approaches. Our staff is eager to answer questions and make recommendations for particular applications. We also welcome user comments, suggestions, and feedback about our aircraft tools, their performance, suitability in various applications, and ways we might improve them.
