  • First comment.

    It worked lousy on a thin piece of aluminum, so it must be useless on steel or other hard metals.

  • @scalabration these dont cut as agressivley/ fast as standard Hss bits due to their tip geometry, but on hardened steel they are extremley effective I am a safe engineer and regularly use these bits on safes which have steel hardened to rockwell #65. All in all a top class bit for the price. The carbide tip doesent chip easily either.

  • @CRF80TOP55 Hammer acts as if someone was hitting the back the drill while it is in use with a hammer. This is why they work great for drilling concrete. Hammer action is downward.

    Impact provides the hitting force in a spinning direction. Think of it as hitting a wrench handle while trying to remove a stuck bolt. Impact action is twisting.

  • @scalabration

    it worked lousy because it´s too fat drill, if you first use small drill and then the fat one it will work better.

  • why the driver drill have enough power to drill in concrete?
