Electric diamonds are drilling machines using electricity to make power.It is a conventional product in electric tools, and it is also the most demand electric tool product.The annual production and sales volume accounts for 35%of Chinas electric tools.The main specifications of electric diamonds include 4, 6, 8, 10, 13, 19, 19, 23, 32, 38, 49mm, etc. The number refers to the maximum diameter of drill bit with drills with a drill with a tensile strength of 390N/mm2.The maximum diameter of the maximum drilling of non -ferrous metal, plastic and other materials can be 30-50%larger than the original specifications.
The difference between electric diamond and electric hammer
Electric diamond (impact drill): can be drilled, drilling iron, and drilling, but not drilling concrete. Some impact drills say that drilling can be drilled with concrete, which is actually not feasible, but the layer of the drill tiles and the brick is thin.There is no problem.Take the interior, the ceiling is a reinforced concrete, and it is laborious to use a shock drill.Electric hammer: Use it on hard objects such as cement, brick, and stone.During the work, two types of exercises are made, one is axial shock vibration, and the other is the slow rotation of the drill.Puning in thick concrete is very easy.
The difference between electric diamonds and impact drills
Electric diamonds have only rotation methods, which are especially suitable for drilling on materials that need small force, such as cork, metal, tiles, tiles, etc.The impact drill relies on rotation and impact to work.A single impact is very mild, but the impact frequency of more than 40,000 times per minute can generate continuous force.Shock drill can be used for natural stones or concrete.They are common, because they can use the "single diamond" mode or the "impact drill" mode, so it is a basic electric tool worth choosing for professionals and themselves.Electric hammer relies on rotation and beating to work.A single knocking force is very high and has a frequency of 1,000 to 3,000 per minute, which can generate significant force.Compared with impact drills, the electric hammer requires the minimum pressure to drill into hard materials, such as stones and concrete; especially relatively hard concrete.
How to change the drill head for electric drills
Method 1: Holding a small circle with a drill head in one hand, and the big one in the other hand, the big one on the top, twist the drill or loosen the drill head.The black round button on the handle is protected.The one inside is used to adjust the speed.Method 2: Remove the drill head: Put the impact on the ground (the drill head facing up), press the plastic ring at the root of the drill head down, hold the drill with your right hand, and rotate the drill with the left and right to remove it.Install the drill: Still an upside -down shock drill. Press the plastic ring with your left hand down, and take the drill with your right hand to rotate and insert it.
Electric diamond price
The price of electric diamonds is generally around 200 yuan. Electric diamond products are compulsory certification products stipulated by the State Certification Commission. Therefore, when buying, you should first check whether the tool has a 3C logo. The method of consulting is generally. On the outer packaging of the toolOr is there a 3C sign on the nameplate of the tool? If there is still doubt about this (because the manufacturer of the electric diamond has not passed the annual supervision review, the State Council suspension or cancellation of its certificate) can be on the website of the State Consultation Commission to consultWhether the 3C certificate of this tool is currently valid.
