I have had the woodscrew version of this for about 15yrs so the concept itself is not new.

 

Good if you are drilling and tapping lots of identical holes. Not so good if you are usually tapping one-off holes in a wide variety of sizes (I would guess not available across the full range of UNC/UNF/BSW/BSF etc) and no use at all for blind holes.

Tried them still use drill and separate tap very brittle and won’t drill and tap much above 4mm thick

Things like this always look great but in everyday situations, offer very little. I would rather do it once, slowly, bit of grease on the tap (or tallow for the old school toolmakers) .....get it straight and right rather than crashing through it and as Alec said....no good for blind holes!
