How many guys does it take to hold the drill itself? :D
I think I have to call BS or should I say AI on this.
The drill shows a round shaft and maybe a taper since there is what looks like the tang of a morse taper. The largest twist drills seem to be about 90mm or 3in diameter and this exceeds that by a bunch. Also, the guy is holding it rather than it being in a fixture.
Maybe it is just an advertising model, but a solid hunk of steel that size would weigh more than that guy could handle. A 6" diameter (the image looks larger than that) 6ft long of 1018 is over 575 pounds. Even if it was only half that weight because of the twists, whipping a 300 pound hunk of metal is BS or AI...
I don't like the angle, do it over
also, look at that tiny drive tang on the back end and that small taper.
Something not right there.
