Whether for large or small drywall projects, this screw attachment with a ¼" hex drive and depth stop reliably assists you in achieving perfectly countersunk screws in series. By ensuring the correct plunge depth for each screw, you secure optimal hold for the drywall panels and make subsequent taping work easier. You only need to set the magnetic bit holder with depth stop to the required plunge depth once, allowing for precise screw placements in series thereafter. The patented plastic cap features a window that provides a clear view of the bit and screw, keeping you informed of your progress. The bit can be replaced if necessary, and a Phillips® 2 bit is included.
