Based on my experience with this industrial and scientific woodworking tool, I am highly disappointed with its performance. The spade bit failed to deliver precise and fast cuts; instead, it made rough cuts and broke off splintered wood, ruining my project. The only pro I could find is that the bit is made of sturdy material. However, that does not make up for its lack of accuracy and precision. In conclusion, I would not recommend this spade bit to any woodworker out there.
