Bosch Tools. Gen2 Compact Tough Drills offer small and light drill/driver and hammerdrill/driver options. Available models weigh 4.2 pounds or less, depending on the battery selected, and measure just 7 inches long for the drill/driver, or 7.5 inches for the hammer-drill/driver. The 18-volt tools also feature a 4-pole motor and all-metal gear train and clutch for added power. A small-diameter grip makes the tools more comfortable to hold. Kits include the tool, charger, battery, case, and bits. 877.267.2499.
