Review on Bosch NKMT22 Daredevil Auger Bits by Shane Jenkins

Bought to motivate 6x6 logs. The beat is huge and very well built. Because it has a threaded tip, it will continue to function once started with minimal effort. Be warned, this is so big and requires so much torque that you absolutely need a low speed drill. They aren't joking when they say the max revs are 600 rpm. I bought a low speed port cargo rig and this combo worked really well. any other drill will just burn through. (and the wood was pine!) Also, pulling this thing out can be a pain. Huge chips tend to get tangled, and because of the threaded tip, you can't get them out without throwing them backwards. I would recommend drilling a pilot hole so the threaded tip doesn't hold the drill bit in the hole. Overall a very good drill!
