TENZ Stairs Thread Technology works by displacing the wood rather than cutting, tearing or milling it. This significantly reduces friction, reducing both the physical effort required by you and the energy input from the drill. Because the wood is displaced and not milled or cut, it closes in on the screw giving a firmer bond.
