As a professional in the Industrial and Scientific field I was thrilled with the accuracy and precision of this cutting tool .As a result of my tests, I determined that it is the perfect ADDITION to any toolbox, providing durable and effective swaging capabilities for repairing or modifying various materials. However, the only downside I found was that it could be a little intimidating for those not accustomed to working with industrial drill bits. Overall, a fantastic product that delivers results!
