Cuts a hole for the internal viewfinder well. The blades are very sharp and cut cleanly. Place masking tape where you plan to start drilling and press firmly against the wood. When the drill just starts to come out the other side, wrap tape around that spot and start drilling from the other side. You should be aware that this bit is very shallow and will only remove 1/8 inch of wood at a time. After that, you need to stop drilling (you don't really have a choice) and use a 1/2-inch drill bit to remove the wood burr created by the tool. Then continue drilling with the drill and repeat. It took about 10 or more of these cycles to drill a hole in the front door.
