What is a climb cut?
Its when it climbs out of your hand and into the wall
(I haven't heard that term either)
I was cutting a small piece of wood less than 3" by 2" on my table saw about two months ago (thought I could just shave it a hair trying to save time) anyway it rode up on the top of the blade and shot out like a gun right into my thumb and took half of the nail with it. Moral of the story: trim your nails..........
just kidding, There are no short cuts when it comes to safety
Edit: climb cut
--- A router
cut made in opposite direction from normal. That is, a cut made such that the cut is in the same direction as the pull from the rotating motion of the blade. This is NOT a good idea for full cuts, because control is poor, but it is invaluable as a way of avoiding edge chipout
by making a series of very short, shallow climb cuts (until you have made a short full cut) just long enough to assure that the bit won't cause chipout as it exits from the edge when making the full cut in the normal direction (where the blade's rotating motion pushes against the wood as the cut is made). If the edge is still square, a backing board
is preferable to a climb cut, especially if you are not accustomed to making climb cuts, but if the edge has already been routed, a backing board may not be any use.
