4 in. HOLE DOZER bimetaal gatenzaag met 3/8 in. as en centerboor

Cut through a cast iron pipe like it was butter—the tooth form really does grip and rip without grabbing. The arbor locks in tight, so I didn't have to stop and re-tighten mid-cut. This thing earned its keep in one afternoon.

Tackling a demolition project in an old building, this saw chewed through steel studs and copper pipe without even slowing down. The built-in arbor makes swapping sizes a breeze, and after a dozen cuts, the teeth still look fresh.

The Rip Guard tooth design on this hole saw lived up to its billing when I drilled through some old steel electrical panels—not a single tooth broke. The arbor and pilot bit were already assembled, which saved me time digging through my toolbox.
