These industrial drill bits are an absolute must-have for any workshop! I was pleasantly surprised by their high-speed performance and durability. The bits are versatile and can be used for a variety of materials. The aggressive design allows for quick, clean cuts without slipping. However, the set is a little on the pricey side. Despite the cost, they are worth every penny for their precision and efficiency. Overall, a fantastic addition to any industrial and scientific toolkit.
Great set for very fine work. I used a #67 drill bit to drill a hole in thin aluminum to get a pinpoint view of the total eclipse. #67 made a clean hole and it was the perfect focal length hole I wanted. It also completed my set of drill pointers with numbered, fractional and letter designations. I think I need to start making a bunch of metrics.
