Consumers depend on "experts" to tell them how things should work, or how they should do something, or what they should be purchasing. The idea is there is always someone out there who has more experience than you, problem is, you have to be smart enough to know when these supposed "experts" show they dont know what they are talking about.
Perfect example...
Now first let me say, this has nothing to do with the Drill bits, this is all amount the Terminology used in the video about the drills.
First Mistake... "I showed you the advantage of a impact driver over a traditional Drill" talking about drill bits
Second Mistake... "A traditional drill bit is not designed to take the hammering effect of a impact driver"
Third Mistake.... "I'm a pretty strong guy and having to put a lot of force to drive that through"
Fourth Mistake.... "one of the great things about this drill bit is it works on impact drivers as well as standard drills"
Fifth Mistake.... "Works on impact drivers as well as standard drills"
And the problem is, only listing 5 is being nice.
First whole issue is the guy is telling you these bits work in a Impact Driver and the fact is, they dont. Impact drivers do not have chucks on them, they have 1/4" drivers and can only use bits with a 1/4" drive on them (which these bits dont have) What he means to say, is hammer drill and yet he doesnt. There is a HUGE difference between a hammer drill and a impact driver.
A hammer drill, is first of all, a drill. They have a chuck and can take normall drill bits or bits made for use in a hammer drill. When the drill is put in "hammer mode" (yep you just thought about MC Hammer didnt you, The whole "hammer time" thing just popped into your head, its ok, I wont tell anyone. Actually, yes I will!! ) ANYWAY, when the drill is put in hammer mode, it spins just like normal but the bit goes in and out like you are hitting the back of the drill bit with a hammer (hence the name hammer drill) The spinning chuck has no more torque than normal and the point of a hammer drill is to help drive the bit through surfaces like Concrete.
A Impact driver is first and foremost a DRIVER, not a drill. It is mainly used to drive screws. Most of them do not allow you to turn off the "impact" part of it. When large amounts of torque are applied to the spinning motion, Like you are driving a long screw into dense wood, a hammer type motion is put in the direction of the spinning chuck. The point being to increase the torque and help it spin. It DOES NOT create a motion that moves the bit in and out. It simply helps the chuck turn to be able to drive the screw in.
so take this guy, who is at least giving you the impression he is a professional and knows what he is doing, realize he doesn't understand something that should be basic in the power tool industry and add to the fact that he believes he needs to be a big strong guy to make some of these holes (the point of a tool is to let the tool do the work, and not you. If you are leaning into something that hard, then you are doing something wrong) Add to all that he is comparing apples and oranges with the black oxide bit to a masonry bit...... REALLY? I think thats enough to prove Sears is doing the world a big disservice here.
I'll stop now...
