In the field of metal working, Angle iron is a common structural material and often needs to be drilled. However, in actual operation, we sometimes encounter the situation that the drill does not move the Angle iron, which not only affects the work efficiency, but also may cause damage to the equipment and the drill. So, what is the reason why the drill does not move the Angle iron? How can we solve this problem?

The drill does not move the Angle iron

Improper bit selection:

The hardness and strength of the Angle iron is high, if you choose an unsuitable bit, such as the diameter of the bit is too small or the material is not suitable for processing the Angle iron, it is easy to drill the situation.

Improper use of drill:

When using the drill bit, if insufficient pressure is applied, the speed is set improperly, or no lubricant is used, the friction resistance of the drill bit will increase, resulting in the drill bit is difficult to drill into the Angle iron.

Bit wear or damage:

After prolonged use of the drill, its cutting edge will be worn or damaged, which will greatly reduce the cutting ability of the drill bit, making it difficult to drill into the Angle iron.

Angle iron material problem:

If the material of the Angle iron contains impurities or uneven hardness, it may also cause the drill to be immovable.

Correct selection of drill bits:

Select the right bit according to the material and thickness of the Angle iron. Generally speaking, the drill diameter should be greater than the thickness of the Angle iron, and the material should be suitable for processing the Angle iron. For example, for harder Angle iron, you can choose a high-speed steel bit or a carbide bit.

Correct use of drill bits:

When using the drill, adequate pressure should be applied and the appropriate speed set. At the same time, lubricants should be used to reduce the friction resistance of the drill. In addition, attention should also be paid to the cooling and heat dissipation of the drill to avoid overheating and damage to the drill.

Regular inspection and maintenance of drill bits:

Before using the drill, check whether the cutting edge is sharp and whether there is damage. During use, the bit with severe wear should be replaced regularly. In addition, the drill should also be regularly maintained and maintained, such as cleaning, oiling, etc.

Handle the Angle iron material problem:

If the Angle iron material contains impurities or uneven hardness, it can be pretreated first, such as annealing, quenching, etc., to improve its processing performance.

To sum up, there are many reasons why the drill bit does not move the Angle iron, but as long as we correctly select the drill bit, correctly use the drill bit, regularly check and maintain the drill bit and deal with the Angle iron material problem, we can effectively solve this problem. In the process of metal processing, we should always pay attention to the performance of the drill bit and the machining performance of the Angle iron to ensure the smooth progress of the drilling operation.
