We used standard drill bits and drilled holes in softwood and hardwood. These smaller drills are not designed to withstand that type of activity, so we tested them in practical drilling and driving situations. We also awarded points based on ergonomics, the ability to adjust clutch settings, and whether they came with additional features-such as work lamps.įor the drills with less voltage such as 12V and 7.2V, we did not subject them to intensive drilling as we did the others. We did, however, award points for power and torque. We didn’t feel it would be a fair assessment of the tool to award points on runtime. However, we did not award points for runtime because lithium-ion batteries may perform better or worse for a variety of reasons, and things like being stored in subfreezing temperatures can reduce their viability. At the end, we added up the points from the rubric to get a better overall picture of how well each drill did.Īs we drilled holes, we noted each tool’s runtime. If it drilled through pine moderately well, we gave it a 2, and if it drilled through pine exceptionally well, it got a 4. For example, if a drill did not drill through soft pine easily, it got a 0. We recorded each drill’s performance using a rubric and awarded numbers from 0 to 4. The larger a bit’s surface, such as an auger bit or a 2-inch hole-saw bit, the more power a drill must have to successfully drill through wood and other materials. We tested each of the 18V and 20V drills using a variety of drill bits-both standard and specialty, such as auger bits and paddle bits-to determine how much power and torque they had. We had to know whether they would overheat and how much torque they could generate. We demanded more from the powerful models-the 18-volt (V) and 20V drills with ½-chucks-because these are the drills DIYers purchase to construct larger projects, such as garages and sheds. We separated the drills by voltage to remain product-appropriate and performed the most aggressive tests on the highest-voltage drills. We started by charging the batteries fully, so each drill had a fair shot from the outset. To earn a spot in this cordless drill lineup, every power tool was extensively tested.
