BAR CUTTER AND BAR BENDER
Bar cutter
Bar Cutter is a tool that has been specially designed so that it can be used to cut reinforcing steel according to the planned size. The use of this tool is very helpful in construction projects. Usually the production of reinforcing steel has its own size, which is 6m. 9m and 12m. Therefore, to support concrete construction work, the reinforcing steel must be cut to the desired size. In addition, reinforcing steel has two types based on its shape, namely plain concrete reinforcing steel and fin reinforcing steel. In plain iron reinforcing steel, it has a circular cross-section and has a flat, finned surface. While finned concrete reinforcement has a surface shape with transverse fins and longitudinal ribs which are used to increase adhesion and resist the longitudinal movement of the bars against the concrete. Well, with the Bar Cutter machine, it certainly makes it easier for every job that uses large amounts of reinforcing steel. For example, in large constructions such as buildings, bridges and so on.
Types of Bar Cutter Based on How It Operates
Bar Cutter is specifically used as a reinforcing steel cutting tool so that it can get the desired size. Based on the way of operation, this tool is divided into two types. Including the following.
1. Electric Power Bar Cutter
As the name implies, this type of Bar Cutter is an iron or steel cutting tool using electric power. Through this tool can produce steel with various diameter sizes, both in all main reinforcing steel. This type of Bar Cutter that uses electricity certainly makes the process easier and faster. No wonder this tool is often used in large construction projects to be more effective and efficient of course.
As for the electric Bar Cutter, it is usually equipped with inner cutting blade openings ranging from the smallest to the largest. The large blade opening on the Bar Cutter is usually special for cutting iron with a large diameter as well as several smaller diameter iron or steel. The way the Bar Cutter works is also fairly simple, namely by entering the iron or reinforcing steel to be cut and then pulling the cutter lever. It didn't take long for the iron or reinforcing steel to be cut.
2. Manual Bar Cutter
Manual Bar Cutter is an iron or steel cutting tool that is operated manually by workers. The use of this manual cutting tool is usually on iron or reinforcing steel which is located at the installation location of iron or reinforcing steel with a smaller diameter. Of course, the use of a manual Bar Cutter is not effective in cutting iron or reinforcing steel with a large diameter. Instead, it prolongs the time or process so that the efficiency is no longer there. Therefore, the use of this Bar Cutter must be adjusted to the needs of cutting iron or reinforcing steel. That way, the process won't take long and is certainly more effective.
Use of Bar Cutter
As an iron or steel cutting machine, Bar Cutter has a wide range of specifications. Of course, each machine with different specifications is also equipped with different cutting capacities. Usually, the capacity of this machine corresponds to the size or diameter of the iron or reinforcing steel. Therefore, before starting to work on the concrete frame, you should know the diameter size of the iron or steel reinforcement first. So that the specifications of the tool used can be adjusted to its size. After that, proceed to the process of operating iron or steel cutting tools. Its operation is adjusted to the type of Bar Cutter, namely electric or manual. This is as described above. However, it is important to remember that cutting iron or small diameter reinforcing steel can be done all at once. Meanwhile, large diameters must be done one at a time to be more secure.
The Relationship Between Bar Cutter and Bar Bender In Construction Projects
In working on a construction project, Bar Cutter is usually equipped with other tools, namely Bar Bender. Both are complementary tools used in the manufacture of concrete frames. The term bar in this tool does refer to reinforcing steel bars. Of course, both tools have the same important function. If Bar Cutter is used for cutting then Bar Bender is used for bending. So, the process of working on this concrete frame begins with cutting the steel as needed. After that, it is continued with the process of forming the frame through bending according to a predetermined pattern. If you have been directly involved with a construction project in the field, of course, you are familiar with these two tools. But if you haven't, we'll give you an idea of how to use the tool.
Bar Bender
The bar bender is a project tool used to bend threaded reinforcing steel. The bar bender is very helpful for the blacksmith in bending so that the productivity of the craftsman is increased. This tool uses the help of an electric transformer with a fairly high electrical power. The way this Bar Bender works is that the steel to be bent is inserted between the press shaft and the bending shaft and then the angle is adjusted according to the desired bending angle and the length of the bending. The ends of the reinforcement on the bending shaft are held using a bending wrench. then the pedal is pressed so that the bending wheel will rotate according to the desired angle and bending. The bender bar can adjust the bending angle of the reinforcement simply and neatly.
Types of Bar Cutter Based on How It Operates
Bar Bender is specifically used as a tool for bending reinforcing steel so that it can get the desired size. Based on the way of operation, this tool is divided into two types. Including the following.
1. Electric Bar Bender
Electric Bar Bender is a reinforcing steel bending device using electric power. This type of Bar Bender is capable of bending even large diameter reinforcing steel. How to use it is quite easy, namely the input of iron or steel between the shaft and the bending arm. Then press the bend angle and press the button to turn the bending arm.
2. Manual Bar Bender
Manual Bar Bender is a type of Bar Bender that is operated manually by workers. This tool is usually used to bend iron or steel whose diameter is smaller. Or use directly in the field when additional reinforcement is needed.
Use of Bar Bender
Bar Bender is used to bend iron or reinforcing steel without requiring a lot of force. This certainly simplifies and speeds up the process of bending iron or steel. Almost the same as Bar Cutter, Bar Bender as a bending tool also has a capacity that varies according to the size of the diameter. Therefore, this capacity will determine the bending of concrete as needed. After the iron bar or reinforcing steel is cut using a cutting tool, the next step is to bend it using this tool. It should be noted that the bending must be in accordance with the design or design pattern drawing.
The process is also quite diverse, namely one piece of iron or steel can be formed into a ring (square, rectangular, trapezoidal and so on, U pattern, L pattern and many more. The way Bar Bender works is to rely on its two main shafts, the press shaft and the shaft. bend and the wheel to bend. First, put the steel into the press shaft into the bending shaft. Adjust the amount of the bending angle and lock it. After that, press the compression shaft until the wheel rotates and the iron bar is successfully bent.
Tips and Rules for Cutting and Bending of Reinforcing Steel
If you want to use steel cutting and bending tools, we recommend that you prepare a pattern, drawing or frame of reference. If you already have a plan in advance it will make the process easier. Of course in the process of cutting and bending concrete must be done properly in order to produce quality iron or steel. Therefore, there are some rules that must be observed. The rules for cutting and bending iron or steel are as follows.
- Before cutting and bending iron or steel, make sure it is clean from rust, mud, oil and other impurities. This is very important because it can damage the engine and the results are less than optimal.
- Be sure to check the dimensions of the reinforcing steel to avoid cutting and bending errors. Check tables or diagrams that contain information on cut distances, bend angles and the amount of reinforcing steel to be cut or bent.
- When bending the reinforcing steel, be careful not to damage the reinforcing steel.
- The bending of reinforcing steel with a diameter of about 2 cm or more must use a bar bender machine.
- Bending of reinforcing steel should not be done from the opposite direction when the reinforcing steel has been bent.
- Reinforcement steel that has been bent and then straightened must not be bent within 60 cm of the previous bend.
- The bending process of reinforcing steel must be carried out when the reinforcing steel is cold. Meanwhile, the bending of reinforcing steel with the hot method can only be done with the approval of the project quality control.
- The bending of reinforcing steel by the hot method should not be cooled by water.
- Reinforcement steel that is partially embedded in concrete may not be bent or straightened before obtaining permission from the construction planner.
- After the reinforcing steel is cut or bent, always re-examine so that the results are in accordance with the frame or reference drawings.
After knowing some rules of cutting and bending reinforcing steel will give more optimal results.
Tips for Choosing Steel Cutting Tools
Bar Cutter is defined as a tool for cutting iron or reinforcing steel using electric power. No wonder the results are of higher quality and of course easier and faster without spending a lot of energy. There are several different types of iron cutting tools according to their respective specifications. Some of them have bandsaw, plasma cutter and saw off types on cutting machines. However, in some developed countries already use the cold blade type which is shaped like a circular saw. This tool can be used to cut various types of metal materials. Meanwhile, the most popular type of machine in Indonesia is the cut-off machine. The machine can be used to cut various metals from mid steel to aluminum more effectively. When choosing an iron or steel cutting machine, you must pay attention to the power of the machine. This is very important because the engine power has a great influence on the power and torque released when the tool is used. The greater the power will affect the speed of the cutting tool. That's all, there are some other important things that you should pay attention to when choosing a mower. Are as follows.
1. Pay attention to the size of the knife
When choosing an iron or steel cutting machine, you should pay attention to the size of the blade. The size of the blades of this cutting machine is generally very diverse. Therefore, before using it, it must be adjusted to the cutting needs.
2. Choose the machine with the best brand

Usually, cutting machines with well-known brands are easier to get on the market. In addition, well-known brands usually offer guarantees that are of higher quality, more durable and have higher accuracy and are equipped with spare parts guarantees in the event of a breakdown. The design of branded mowers is also better so as to provide comfort and convenience for its users. Although the prices offered tend to be more expensive, the quality produced will not disappoint. Not only that, there's nothing wrong with choosing a branded iron or steel cutting machine because it tends to be more durable and can last a long time. Of course, it will save your budget because you don't need to buy a machine often.
3. Warranty service
Iron or steel cutting machines that come with a warranty tend to be safer. So, in the event of a machine breakdown, you can take advantage of the warranty to repair the machine. Standard Size of Reinforced Steel When performing the process of cutting steel reinforcing concrete, you should know the standard size. This is very important because the type, size and quantity used must be in accordance with the technical calculations. In addition, the measurement of the concrete reinforcement uses a Bar Cutter, where the cutting process is in accordance with the diameter of the reinforcing steel. Well, here are the types, sizes, weights and lengths of reinforcing steel as well as tolerances for size deviations.
