Thanks to my knowledge gained in practice, I can say that this industrial drill bit is a great addition to my collection. It's tough enough to handle heavy-duty jobs without cracking or breaking .The auger creates SMOOTH, clean holes quickly and easily. Industrial and scientific workers will surely appreciate this tool. One con is that it is quite heavy which can be tiring during extended use. Overall, the Irwin Tools 3043004 WeldTech Auger is highly recommended for those in need of a reliable and strong cutting tool..
