8. DeWalt DC983KA XRP Cordless 14.4v drill

Why he'll love it:

Modern cordless drills are almost as powerful as their corded counterparts, but have the added benefit of being able to be used anywhere. For a great heavy-duty cordless drill your Dad will surely love, DeWalt's popular DC983 14.4v 1/2" drill/driver is a great choice. The three-speed transmission delivers up to 1800rpm with a maximum of 450 inch/lbs of torque. An all-metal ratcheting keyless chuck features carbide jaws for maximum bit grip. The kit includes two XRP batteries, a charger, and a storage case to keep everything together.

At only $150 for the reconditioned version, this is a great way to get your dad DeWalt cordless quality at a great price.
