GREAT set! The cutter in the top hole of the handle cuts branches, poles and sticks to diameter and inserts them precisely into the holes created by the drill! You will also use the hole in the top handle to cut the handles to a diameter to go through the top hole so you can use the snail! VERY intuitive and easy to use as well as high quality! This tool makes building awnings, tables, chairs and stairs much easier and faster! I don't go into the forest without them!
