Percussion drill is a kind of equipment for clamping percussion electric drill bit. It is used for drilling concrete foundation, wall, brick wall, granite and installing expansion bolts, plastic expansion pipes and other fasteners in the hole. So, do you know what type of percussion bit? Impact drill bits include high-speed steel drill bits for metal drilling, masonry drill bits, woodworking drill bits, ceramic tile drill bits, etc. What are the precautions for using impact drill bit? Next, let’s learn about the relevant knowledge of impact drill bits.
Classification of Impact Drill Bit
1. High speed steel drill bit is used for drilling metal and it is black. It can drill holes on metal materials such as alloy steel, non-alloy steel and cast iron. Be careful not to rotate too fast during operation, which is easy to burn the bit edge.
2. Masonry drill bits are used to drill holes in concrete and stone materials. The cutter head is made of cemented carbide.
3. Woodworking drill bits are required to drill holes in wood materials. Woodworking drill bit has low requirements for tool hardness, and the tool material is high carbon steel. In fact, metal drills can also drill wood. However, because the wood is easy to heat and the brittle debris is not easy to take out, it needs to rotate slowly when drilling, and the debris often needs to be removed.
4. If it is necessary to drill holes on ceramic tiles or high hardness glass, ceramic tile drill bits shall be used. The tool material shall be high hardness tungsten carbon alloy. Pay attention to control the drilling speed during use.
Precautions for Using Percussion Drill
1. Drill bits of different materials are used to drill different materials. The harder the tool, the worse the toughness and the finer the drill bit, the worse the stiffness. Therefore, we should control the speed of drilling. When drilling, it is best to add appropriate cooling oil or cooling water. Now some drill bits are coated with hard metal film, which is used to drill steel, iron and other materials without heat treatment, which is easy to stick to the drill bit. Therefore, it is best to clean and lubricate the drill bit with soapy water after drilling.
2. Before using the drill bit, it is best to drill a sample hole on the material to be drilled to prevent the deviation and inconvenience at the beginning.
3. Black drill bit is more suitable for iron drilling. They are occasionally used in daily life. It is suggested that it can be used at home.
