Electric drills are commonly used drilling tools. Traditional electric drills use alternating current (wet electricity). It is not convenient to connect the power cord. Today's electric drills have been connected with electric screwdrivers (electric screwdrivers). Most of them have rechargeable batteries. Lithium-ion battery is the main tool, which can be used as a tool for drilling, screwing, and screwing up. It has fewer power cords and is more flexible and convenient to use. Amateurs can consider buying this dual-use electric batch, but want to buy a larger torque, the disadvantage is not to <a href="https://www.worksitetool.com/product.html" rel="noopener noreferrer" target="_blank">drill</a> the wall. Various electric drills There are three main types of electric drills: electric drills, electric drills, and hydraulic drills. Electric drill: It is mainly used for drilling wood. It can be drilled with ordinary iron drills, but it is very difficult. It is necessary to use a small drill floor and turn it into a drilling machine. Need to use a stone puddle, but the effect is poor and laborious. As for the main stone puddle wall, it is not powerful enough. If you only drill one or two holes on the hook or laminate, slowly drilling is also OK. Electric screwdriver: It is mainly used for screwing up and screwing up. It can also be used as an electric drill. It can also drill wood, but the effect is certainly not as good as a real electric drill, and it can't drill sand brick walls. Electric batch generally has a torque control ring, the maximum torque is about 400 pounds. There are also high and low speed gears. When the electric drill is used, the high speed gear is used. When the electric screwdriver is screwed, the low speed gear and the reverse gear on the electric drill can be used to lift the screw. Some electric drills have LED front lights. When you press the trigger, the lights turn on, and it is very convenient to illuminate the working point in front. How to use: Unlike an electric drill, do not press it for a long time. When pressing the screw, press the trigger exhaustively, so that you can force the screw head into the wood with sufficient torque. Hydraulic drill: This is a heavy-duty electric drill, which is mainly used as a diamond poop wall. It must be used with a special hydraulic drill bit. It is generally not used as an ordinary electric drill because it is too bulky and the cable head is different. . 2. Drilling method Drilling principle: Drilling from fine to large, that is, first use a small drill bit to drill small holes, and then change the large drill bit to drill larger holes, can not be in one step, all materials are the same. Drilling wood: This is the easiest, as per the mark drawn, you can directly drill down with a small drill bit, and then change to a larger drill bit, the number of replacements depends on the need. 2. Drilling iron: First draw a circle mark on the hole with a boxhead pen Use a nail to cut the crosshairs in the center of the hole Place the guest (punch center punch) in the center of the crosshairs and hit a dent with a hammer Drill a pilot hole with a young drill Change to a larger drill Repeatedly replace the larger drill bit until the required hole diameter is reached. Note: It takes a long time to drill the iron, and long-term friction generates high temperatures, which may burn the drill bit, that is, overheating will damage the drill bit, and it can no longer be used after cooling. Therefore, it is necessary to add coolant while drilling. It is best to use oil and water. It is better to immerse the drill bit in water at regular intervals to cool down. 3. Drilling tiles: It is best to choose to start at the brick seam, because the tiles will not be drilled or countersunk, because the tile surface is smooth, and the drill will slide around. The construction procedure is roughly the same as that of iron drilling. Binzi drilled a hole in the brick surface to drill down. No binzi can be nailed. 4. Diamond shit: For diamond shit, you need to use the shock wave mode. It is best to use oil pressure drills. Ordinary electric drills can also be used (referring to partition walls), but you need to use stone shit drills. The drills are different from ordinary drills. The naked eye Can also be divided. The pilot hole must be opened with one minute of the nozzle, and then the larger one should be replaced. Because the nozzle is forced to press against the wall when drilling the wall, the young body of the one-point nozzle is very easy to break, so you need to buy a few more. If you use a hydraulic drill, you need to use a hydraulic drill bit, which makes drilling easier. When you drill, you must press the drill bit against the wall. Hold the handle and the trigger switch with one hand, and hold the front drill handle with the other hand. It has strong resilience and should hold the drill tightly with both hands. It is best to use a metal detector to check whether there are wires and metal obstacles at the drilling position when drilling. 3. Electric drill to drill Need to drill vertical and accurate drilling, handheld electric drill is not possible, do not need to buy a professional drilling machine, go to the hardware shop to buy a drill stand, you can immediately turn a portable electric drill into a drilling machine, but remember to also buy a drill press vice to clamp Tight workpiece. 4. Other matters The bit that has just finished drilling a wall or iron is very hot and should not be touched immediately. In order to avoid dust scattered when drilling the wall, use the long pipe of the vacuum cleaner to align the drilling position before drilling. When drilling smallpox, a wide-mouth bottle rubber cap can be set on the hydraulic drill bit to hold the falling dust.
