Bosch PS32-02
CR’s take: This 12-volt drill is one of only three models in the general-use category with a brushless motor. That means the Bosch PS32-02 can deliver a tad more power than if it used a traditional “brushed” motor. It also means it will run longer on a charge and may have a longer life span. The Bosch is highly rated for handling.
DeWalt DCD701F2
CR’s take: This 12-volt general-use drill is light enough that you won’t tire when swapping out an overhead light fixture but forceful enough to bore holes in hardwood without bogging down. That’s what you get with a brushless motor.
DeWalt DCD991P2
CR’s take: This 20-volt heavy-duty brushless DeWalt DCD991P2 is one of our best performers, snagging top ratings for power, speed, and run time. But the hefty 5-amp-hour battery that produces all that power makes this drill heavy, unbalanced, and a bit awkward to handle.
Hilti SFD 2-A
CR’s take: The unique Hilti SFD 2-A drill falls in our light-duty category because of the limitations of its fixed ¼-inch chuck. That’s not a problem, though, if you’re not drilling large holes. Plus, it goes for half the price of many cordless drills with similar capabilities while still proving to be reasonably powerful.
Kobalt KXDD 1424A-03
CR’s take: This dynamo can drill fast, garnering a top rating for speed. Its performance and great price earn this compact Kobalt KXDD 1424A-03 a CR Best Buy designation. The 24-volt heavy-duty brushless drill packs the power of drills costing twice as much.
Makita FD07R1
CR’s take: This general-use Makita is the third brushless model in our general-use category. It weighs just over 2 pounds and stands barely 6 inches tall. Despite its slim profile, the Makita FD07R1 aced our power test and packs a serious punch, making it a solid alternative to some of the larger 18- and 20-volt models.
Makita XFD061
CR’s take: What this recommended 18-volt brushless Makita XFD061 lacks in power it makes up for in speed. Wallet-friendly, it aced our speed test and drills holes plenty fast. With its ½-inch chuck, the compact and well-balanced design makes it easy to handle while still maintaining the ability to tackle tough jobs.
