How the test was done: At the beginning of every test, each drill received a freshly charged battery. Screwing power: After setting the speed selector set to HIGH, all the clutches were set at 10. If that proved insufficient, then we dialed up the clutch until the drill was able to successfully drive a 1¼-inch-long fine-thread drywall screw into ½-inch-thick drywall and 2x pine lumber. Each fastener was driven to the same depth using a drywall bit. The test continued until the drill couldn’t sink a screw completely. Drilling power: Using a new Irwin ¾-inch spade bit and a speed selector set to LOW, we bored hole after hole through ¾-inch-thick red oak until the battery conked out. Torque: For this torture test, each drill was fitted with a ⅜-inch socket so that we could drive a 3-inch long, ⅜-inch-diameter lag bolt into a pressure-treated pine 4x4 topped with a 2x4. When the tool stalled, we measured how much of the bolt remained above the lumber’s surface.

Milwaukee 2410-22

Price: $150*; Milwaukee Test results: Sank 509 screws, drilled 37 holes, recharged in 33 minutes. Torque test (driving a lag screw): 4 stars. My two cents: “Smooth, consistent power up until the very last fastener. Didn’t bog down in the hole test. Shuts down if overloaded to prevent motor or battery damage.” Tool stats: 2.5 pounds, 250 in.-lbs. of torque, 1,500 max rpm, two speeds, 22 clutch settings, LED task light and battery-life meter, two batteries. Warranty: 5 years on drill, 2 years on battery. *All prices based on manufacturer-approved online distributors.

Hitachi DS10DFL

Price: $100; Hitachi Test results: Sank 403 screws, drilled 20 holes, recharged in 40 minutes. Torque test (driving a lag screw): 2 stars. My two cents: “Very comfortable, though I had to move the clutch to 13 to sufficiently sink the screws.” Tool stats: 2.2 pounds, 195 in.-lbs. of torque, 1,300 max rpm, two speeds, 22 clutch settings, LED task light, two batteries. Warranty: lifetime on drill, 2 years on battery.

Skil 2414-02

Price: $95; Skil Test results: Sank 515 screws, drilled 28 holes, recharged in 49 minutes. Torque test (driving a lag screw): 1 star. My two cents: “One of the least powerful in the lag-bolt test, though it did drive a good number of screws. The battery behaved much like a NiCad in that the battery performance would die, then after a minute of resting it would come back to life. The tool’s battery gauge was inaccurate.” Tool stats: 2.6 pounds, 284 in.-lbs. of torque, 1,500 max rpm, two speeds, 16 clutch settings, battery-life meter, two batteries. Warranty: 1 year on drill, 1 year on battery.
