This brand is among the best. The teeth start and stay sharp as a needle. For cutting wood, the saw is unsurpassed. For metal, a stone support is needed, otherwise the teeth will break (happened to me) - the sharp teeth caught and twisted the drill instead of the saw. Even after losing three teeth, the saw still cut through 1 1/2 inch thick wood with ease. The hole in the side made it very easy for me to remove the drain plug.
