These Bosch blades worked nicely with my older Makita jig saw to make some fairly tight curved cuts in 3/4" hard maple. The cuts made by these 12TPI blades were actually fairly smooth and didn't require too much additional clean up. The two blades that I've used so far still seem sharp and cut well. I've used many other Bosch jig saw blades over the years and they always seemed to be good quality. I think these blades are also decently made and reasonably priced at five to a pack.
