One of the newest innovations in the cordless power tool market is the drill with interchangeable heads. These heads range from a drill to a sander and even an inflator. We decided to see if it stands up to the hype by putting Craftsman's Bolt-On through a variety of tests.

Craftsman's Bolt-On kit (PN#16496, $99.99) is available at Sears or sears.com and includes the handle/base unit, the drill/driver head, a 20V lithium-ion battery, and a revolutionary QuickBoost charger. To really test this product, we ordered the drill/driver combo, the hammer drill attachment (PN#34975, $29.74), the impact driver attachment (PN#34973, $34.99), and the high-pressure inflator attachment (PN#3497, $19.99).

After opening the box and charging the included battery, we attached the drill/driver head and were ready to start drilling. The assembled drill weighs in at just under three and a half pounds, so it won't fatigue your hand when using it all day. Speaking of using it all day, we used it on a project for six hours before it finally threw in the towel. However, the convenient QuickBoost charger returned the battery to 100-percent in less than half an hour. In our hands, the grip was fairly comfortable. The only gripes we have are that the location of the included combo bit caused the flat-head end to scratch our hand while using the drill. Also, the grip got dirty very quickly due to the light gray coloring. Other than that, it felt like a quality drill.

The drill attachment powered through everything we threw at it, from ¼-inch plywood to ½-inch-thick steel plate. The two-speed hammer drill, at 24,000 blows per minute, had the cajones to power a lag bolt into a cement pad without batting an eyelash. Next, we attached the high-pressure inflator, which according to the manual has a maximum rating of 120 psi. However, when we attempted to add air to a tire on our 2013 Ford F-150, it tapped the mat like Cain Velasquez being choked out by Anderson Silva. Fortunately, we were able to add air with the inflator when the truck was jacked up with no weight on the tire. The next kink we ran into was when we tried to remove a lug nut that had been torqued down to 80 lb-ft. According to the insert that came with the impact driver attachment, the torque rating is 1,300 in-lb, which converts to 108 ft-lb. Its real-world torque didn't reach that number at all, but it did not have trouble screwing in a 3-inch wood screw into a 4x4-inch piece of pressure-treated lumber. I guess it wasn't meant for tearing apart a pickup truck.

Overall the Bolt-On handled most tasks with ease. Even though it didn't excel in every category, it does offer the handyman several tool options in one convenient package at a wallet-friendly price. If you are in the market for a new drill/driver, you might want to think about the Bolt-On. Since the other attachments are only $20-$40, you can purchase all of the heads for a fraction of what each tool would cost you.
