I needed to square a hole in a replacement manure fork handle. I was originally looking for a corner chisel, which was not easy to find, and once found; they are expensive! Decided on this/these. Stuffed a drill bit in reverse into the 12.7mm/ 1/2" sq chisel for alignment and used rubber-bands to hold a line level across the top flat to keep me on track, using a strap of rubber between the driven end collar and vise grips to adjust .Slow go w/ a dead-blow mallet, needing to extract the chisel frequently to clear the shavings packed into the alignment drill until I was significantly deep.. But patience prevailed and it created the hole I needed.A considerable volume batch of 30 minute epoxy mixed w/ saw dust to load the hole and paint the fork end. Let it cure a couple of days. Good to go....Solid.! Total cost_, I could have bought a new fork. BUT I'd then re-experience the problems I have had with this original one, (fork eventually loosened in the handle, which I extracted and welded a stud onto to lengthen, then epoxied back together w/ the original handle, which a couple of years later rotted w/in the upper region of the metal sleeve). This now will LAST, likely past my life time.Plus I've occasionally wished I had a means of squaring holes; which I now have the tools to do.

These are a great set if you're not looking for production grade tools. They cut well in softer wood but will overheat if you're not careful in the hardest of wood. Very economical for most home woodworkers, as long as you understand their limitations they will work well.
