Piła do otworów bi-metalowa 2 cale z trzpieniem 3/8 cala i wiertłem prowadzącym

Installed it on my drill and cut through stainless steel sink with no wobble—the Rip guard teeth held up perfectly. For the clearance price, this is an absolute steal.

Cut through a dozen 2x4s with this hole saw and the pilot bit stayed perfectly centered the whole time — no wobble at all. That Rip guard tooth design really makes a difference on a long cut.

I was skeptical about the "Rip guard" tooth warranty at first, but after cutting through some thick old deck boards this weekend, every tooth stayed sharp and intact. The pilot bit kept the cut dead center without any wobbling.
