As a professional in the Industrial and Scientific field, I have tried a number of different tools for deburring and countersinking .This product, however, exceeded my expectations. As a result of using this innovative tool, I found that it significantly increased accuracy and efficiency when working with various materials. The titanium construction also improved the durability AND longevity of the bit. The only downside was the initial cost but it is worth the investment for the quality result it produces. Overall, highly recommend this product for anyone in the cutting tools industry..
