It is recommended using a HI Helix drill bit when making micro-Injections to minimize any wounding and to allow for faster closure. When drilling into a tree you must always take care not to wound the tree more than you need to. It is also essential that drill bits be disinfected before each use to prevent the spread of any diseases between trees.
