Why to buy Stanley 500W 100mm Rotary Hand Drill (STDR5510C) :
Hammer Action drill also known as a rotary hammer, is a rotary drill with a hammering action. The hammering action provides a short, rapid hammer thrust to pulverize relatively brittle material and provide quicker drilling with less effort. A hammer drill has a specially designed clutch that allows it to not only spin the drill bit, but also to punch it in and out which is suitable for drilling into masonry.
A variable-speed drill with an adjustable clutch gives you versatility for drilling different materials and using a variety of bits. Drilling softwood, hardwood, metal and masonry all require different speeds and torque, or rotational force. Harder materials and larger bits require lower speeds and more torque, while higher speeds and lower torque work with softer materials and smaller bits. The drill trigger controls the speed. You set the clutch to the desired torque level. A properly adjusted clutch keeps you from driving a screw too deep and reduces the possibility of stripping a screw head or snapping a screw off.
