Anyone who cares about speed is using nailers or screw guns. Or has a drill and an impact driver. This really just turns one problem into a bunch. I'll point out the significant ones haven't seen so far 1. It has no self-centering capability, because you've removed any split point 2. The hole diameter is massive compared to the screw head you can drive because of how it must be designed. Either you are limited in the minimum size of the fastener (IE it's bigger than you want), or the drive is smaller than you want. Example: Let's say this thing will drill like a 1/4" inch hole and then you want to use a 5/16" fastener in that hole. You'd normally have a t-40 head on that fastener, but they literally can't. The width of just the inset torx portion (IE with no accounting for the bit taper and such) is > 1/4" (it's 6.6mm), so they have to undersize the drive. Probably all the way to t-20, maybe t-25 if they are lucky. That's insane. There is maybe a small range of diameters that hit the right sweet spot. 3. The effective point angle here is basically unusable for anything but soft to medium hardwoods. On top of that, because of the flutes they removed, and the fact that it is hard to keep sharp, it will cause more tearout. This will be made worse by having an effective 4 flute head instead of a 2 flute one. If this was in a drill press or a machine, it would be better than the 2 flute one, but in a drill/driver it's just going to add a lot of chatter and increase tearout. It's the same effect that happens if you try to use a 4 flute or 6 flute countersink in a drill driver vs a one or 2 flute one. The extra flutes make it worse because you can't hold it rigidly enough 4. Drilling and driving are very different applications - you aren't driving the screw in at 2000rpm, and you aren't trying to drill with super high torque. Expect to either snap lots of screws, or break lots of drills, depending which wrong tool you use :) 5. As it dulls, it will not just lose the ability to drill, but will start very quickly slipping when you try to drive the screw. 6. It is impossible to sharpen without custom jigs or automation. There are useful drill+something combos, but i do think we found them all already (IE drill+taps are useful, as are drill + c'bore and drill + c'sink) I don't think this is one of them.
