Furniture is made with all types of different sized screws. It can be quite frustrating to have multiple tools on hand and have to fiddle until you find the right sized screw head. This 64 bit set is literally all I need for any furniture project. With two screwdriver sizes, you can install and remove the tiniest screws up to the largest with ease. The ratcheting motion makes it easy on your hands to gain torque. The head on the larger screwdriver swivels 180 degrees, making it easy to fit into awkward spaces. I use this kit every single day and I absolutely LOVE it!
