6. DeWalt D55141R Air Compressor

Why he'll love it:

Air compressors are a very handy item to have in the garage. They can be used to power Nailers, sprayers and hundreds of other air tools and are also useful for inflating things like car tires and inflatable pool toys. When equipped with a blow gun attachment, compressors also become a great tool for cleaning dust off of things. The D55141 is driven by a .6 HP motor that runs quickly fills the 2 gallon tank and runs much quieter than other compressors. Two air outlets enable simultaneous use of two pneumatic devices. Designed tough, the DeWalt D55141 is a powerful little compressor that is small enough to be considered portable, but powerful enough to handle most household tasks your Dad can throw at it.
