Hole Dozer Yleiskäyttöinen Bimetalli-Reikäsahasarja (11 kpl)

Cut through some thick steel angle iron in under a minute with the larger sizes—the bi-metal teeth held up way better than my old cheap set. The included case keeps everything organized, which is a lifesaver when you're on a ladder.

These teeth ate through some thick aluminum angle I had without even slowing down. The 3.5 TPI design really makes a difference on tougher metal jobs compared to my old set.

Cut through half-inch steel plate like butter on the first try, and the built-in hex shank kept the bit from slipping in my drill chuck. Only wish the case had a bit more space for storing extra pilot bits.
