The rotary tool is a DIYers' staple, and I'm equally a fan of its cousin, the oscillating tool. These can tackle cutting, sanding, grinding, scraping and other tasks all in a cord-free package. I find a use for my Dremel 6300-01 120-Volt Multi-Max Oscillating Kit (Amazon; $125.75) on nearly every project.
Flexible LED Flashlight
I'd always considered dedicated Lithium-Ion drivers a luxury item—until the day I actually used one. These tools are much lighter than cordless drills and provide torque conversion for one task: driving screws and preventing screws from stripping.

Durable Digital Camera
Having a dedicated digital camera for DIY projects that can stand up to paint, sawdust, and rugged conditions is a definite peacemaker in families that love to take pictures. The Pentax Optio WG-1 14 Megapixel (Adorama; $149) is waterproof, drop resistant to five feet, and sealed from dust.
Digital Measuring Tape
The light-weight (2.6 lbs) Milwaukee M12 Heated Jacket provides heavy-duty warmth and comfort for up to 6 hours, keeping your DIYer warm during any outdoor tinkering. Even the techies can get on board because there's a powered USB port for charging portable electronics. Milwaukee; $199
Digital Torque Wrench Adapter
Those who regularly work with mechanics' tools will immediately appreciate a digital torque wrench adapter. These add-ons measure the relative "tightness" of a fastener or component, helping DIYers stay in the Goldilocks Zone of safety.
