It's not remotely capable enough. There's a reason you never see one of these things cut something soft like a tomato into even slices (or at all).

Their extremely clumsy fingers/hands can pretty much just open and close. I have doubts they could even fasten a screw using any kind of screwdriver, given the hardware's overall lack of precision and degrees of freedom in their digits.

They have about enough degrees of freedom to grip most things, but not enough to manipulate (such as rotate) something like a screwdriver they are already holding. Some sources claim they can be precise to within around 1 newton with their grip force - this does not include the additional error introduced by the rest of the robot the hand is attached to. This is relevant if they're holding something that is also pressed against a cutting-board. Best case for them is simply holding an object without having to exert further control, since they have some sort of clutch mechanism that decouples the motors and essentially locks their fingers in place. That gets rid of the shaking you'd otherwise see when they have to exert continuous motor effort. You do not have that luxury when you are manipulating something soft, such as when cutting a tomato, or when you're trying to turn a screwdriver in your hands.

We can deduce they are at least an order of magnitude off human precision, likely multiple. These things are not going to cut tomatoes into something you'd put onto a sandwich or burger, then sell to customers, any time soon.
