Spray gun is divided into metal cutting power tools, grinding equipment, tools and assembly rail with tools. Common saws are drills, electric grinders, electric wrench and screwdriver, hammer and impact drill, concrete vibrator, electric planer.
 Drill: The primary specifications are 4,6,8,10,13,16,19,23,32,38,49 mm, etc., the number means tensile strength of 390N/mm steel drill holes across the maximum diameter. Of non-ferrous metals, plastics in conjunction with other materials compared original diameter of a largest drilling big size 30 to 50%.
 electric grinders: The grinding wheel or disc on a tools. A vertical electric grinders and electric angle grinder.
 Power tool-electric wrench and electric screwdriver: used in handling threaded couplings. The transmission of electric wrench within the planetary gear and ball screw groove impact mechanism component. Specifications M8, M12, M16, M20, M24, M30 and the like. Using electric screwdriver or jaw clutch transmission gear transmission, the specifications are M1, M2, M3, M4, M6, etc.
 hammer and impact drill: for concrete, brick and building components within a perforated, slotted, playing hair. With expansion bolts seemed to improve a wide range of pipelines, machine speed and quality of these installing of equipment.
 concrete vibrator: for pouring concrete foundation and reinforced concrete structures when tamping the concrete to stop porosity, improve strength. Direct electric vibrator which high-frequency interference power from electric motor driven eccentric rotation also, the formation for the motor via a 150Hz or 200Hz frequency energy.
 Power tool-planer for planing wood or wood pieces, belonging to the bench plane may also be used for small units. Planer knife shaft out from the motor shaft via belt drive.
