Most of us like using battery powered impact drivers for turning screws. This works in a lot of cases, but can cause problems with stripped screw heads that cam out, or over driving and destroying the holding power of the wood you are trying to attach to. Conventional screw drivers give you more control but can be darn heard to turn, especially in hardwoods. Both of these traditional methods of driving are impossible to use in tight confined spaces. The VMTW Palm Hex Head Tool Driver is the answer to all of these problems .Way more control, way mower power, compact size.
