In the course of this test, we drilled 1,510 holes and drove 375 lag screws.įlex, short for Flex Elektrowerkzeuge, is a German power tool company muscling its way into the American market. After letting the battery and the drill cool off for 15 minutes, we continued hole drilling until the battery died. After that we went back to drilling holes with the spade bit until the tool’s thermal overload circuit prevented drilling. Each screw was ¼-inch diameter and two inches long. 2 and Better”) using a sharp one-inch-wide Speedbor spade bit-the classic design without a lead screw, easily resharpened with a single-cut metal file. To test each tool, we made 25 holes through Douglas fir 2 x 8 (Grade: “No. This can help you finish a project a little quicker than you might be able to otherwise Does the drill come by itself, without a battery and a charger, or does it come with one or two batteries, a charger, and maybe a carrying case?
