This bit is specially designed for drilling and countersinking drywall screws.

The press-fit collar forces the #2 Phillips bit to disengage once the screw is just below the drywall surface. One bit should do an entire room before it starts to wear.

While not everyone would go through these as quickly as a drywaller, they are handy to have in the shop when a planned renovation project finally gets started. Bits are hardened to Rc62.
