This instructable is a quick modification for drill drivers done at Techshop that will help the drill bit driver to seat into a screw head better so you can avoid stripping out the heads of your screws. The taper (point) on a driver bit sometimes gets in the way of it seating snugly into the flat bottomed screw head. As always start with the correctly sized driver for screw you are using.
