Solid Drill. Use it to cut deep irrigation wells in the ground for trees. 1/2" pipe welded to top of handle for hand drilling an 18" deep hole. Insert a 3/4 inch PVC pipe into the hole and attach the mist eliminator to the top of the pipe.
Excellent very sharp, used many times, hasn't lost sharpness, even hit a few nails just cut, thrown away. Made the hard work easier, had to run a few outlets and the ethernet outlets worked like a $100 bit vendor. It was great that he had it in two days.
Drilled many full depth holes in laminated boards with great success. Another work with knife inserts destroyed it on the first try. The fragile shaft is not designed for high torque applications. Works better as a drill because it's easier to pull chips on the go.
