Tool kits from Grainger put the right tool in the palm of your hand. These tool sets come in a variety of models, sizes and specifications. Mechanics tools have every tool you need to work on any auto, including wrenches, ratchets, screwdrivers, pliers and more, and come in kit sizes from 30 pieces up to over 1,200. Smaller tool sets are also available that serve more specialized work, such as electrical and telecommunications installation kits, from 3 pieces up to 116. Insulated tools make working with electrical wiring and equipment much safer and are easier to grip.
