Drilling with an electric drill
Most of the drills have power cord and a cartridge with a key for the clip of drills. They differ but the power (average 500 watts) and the maximum diameter taken by the drill cartridge (10-13 mm). The advantage of modern feather drills is that they can make holes up to 38 mm with a drill with a tail of only 6.5 mm. When working, a feather drill requires a smaller torque (power), but the neatly argue that it pulls out the fibers, has to carefully cut them off, and therefore, for general accuracy purposes, preference is given to spiral drills. However, spiral drills in the process can “take” to the side, especially when drilling to the end, and for this reason it is desirable to use such a drill on a tree that has a pricing gap.
