Double Insulation: An electrical appliance that is double insulated does not have an earth wire fitted. The appliance is designed in such a way that the electrical parts can never come into contact with the outer casing of the device.
Variable Speed: Drills usually have a variable speed trigger, meaning that the harder you squeeze, the faster the electric motor spins the driveshaft. Cheaper models run at a single top speed, but pricier models offer between two and four maximum speed settings.
SDS-Max Shank: SDS stands for Slotted Drive Shaft or Slotted Drive System. SDS bits are inserted into the chuck to make a rotary hammer or a hammer drill.
