When wiring or rewiring your workshop, consider installing extra outlets in the ceiling, positioned over groupings of power tools. Ceiling outlets can be more accessible and can help eliminate tripping over extension cords. If you are setting up or remodeling your workshop, also plan to install at least one outlet every 3 ft. around the perimeter.
When you buy a drill bit set, it most likely will come in a storage case. This case will help you figure out which size bit you need to use. When drilling holes for a pilot or lead hole for a nail, find which slot in the bit case the nail will fit in. The next size down is the bit you should choose. When drilling a pilot hole for a screw, you need to choose two bits. One for the starter hole and one for the pilot hole. Find which slot in your bit storage case the screw will fit in. That is the size of bit you should use for the pilot hole. For the starter hold, use the next smaller sized bit.
