    Increment Borers

    Yes it is...you know it by the time you've driven and removed a few of those, if you really are going that deep in sound wood. But frequently the tree doesn't require use of all the bit length, and having the leverage that the 24 inch handle gives you is a great advantage. When I was doing...

    Increment Borers

    Willie, my longest increment borer is 24 inches. As a practical matter, you won't be able to use about the last 3 or 4 inches of bit length...the handle has to turn and your knuckles need room to grasp the handle and clear the bole of the tree.

    You read my mind, Dave...I nearly added paraphrases of your post, but decided that it would be obvious to any who contemplate use of an increment borer that it only tells part of the tale.

    You also asked what an increment borer can and can't do...some further thoughts. When I use the increment borer to evaluate the condition of suspected hazard trees, I generally bore three spots evenly spaced around the trunk. I stop boring when I hit soft wood. I extract the cores and by...

    Increment Borers

    Since Dave is online and thinking this might be a problem, I'll go ahead, Sean...sorry :D. Really Dave, most times you won't have a problem. Anyone with a decent feel for how things are going, a touch if you will, can usually tell when the threads quit biting. The borer won't be advancing any...

    You can tell them how to get a hung borer to back out, Sean :D.

    Increment Borers

    The first thing you need to understand about increment borers is that they are a delicate instrument that takes a certain amount of skill to use without damaging beyond repair. The cutting tip on the bit is quite thin and brittle. It is very easy to nick or chip that edge by bumping it against...
