I use a piece of 5/16 tubing over the but for a depth gauge. I cut it so it touches the drill and has about 2" of bit left.

This is what we do. And, never a problem finding a scrap piece of tubing!

So you guys sleeve the tubing over the bit. And basically gives you a flexible/visual stop that allows some variation if the bark is thicker
