Hi-Lok Collar Removal Tools

Collar removal tools are for the removal of threaded collars and come in a variety of shapes and sizes to meet the wide range of collar removal that is necessary in the aviation industry. Some collar removal tools work best for aluminium collars, while others are better suited for steel and titanium collars. Space constraints often require the use of special configurations.

Collar removal tools 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 aviation tooling products, their performance, suitability in various applications, and ways we might improve them.
