The difference between impact drill bit and twist drill bit

The difference between impact drill bit and twist drill bit

There are different types of drill bits. According to the drilling method, one is an impact drill and the other is a twist drill. What is the difference between the two?

1. What are the differences between impact drill bits and twist drill bits?

1. The working principles of the two drill bits are different. If an impact drill is used, it achieves the purpose of drilling through rotation and impact. Relatively speaking, it can produce an impact frequency of more than 40,000 times per minute, and this impact force is continuous.

2. If you use a twist drill bit, it makes holes by rotating and cutting. That is to say, it can form a spiral, just like a twist, with two or three grooves. The use of two grooves is the most common, and can be used in hand electric drills or electric hand drills.

3. The impact capabilities of the two are different. The impact drill bit is relatively more powerful and is more suitable for drilling on some natural stones or hard concrete surfaces, but the impact force is not as good as that of the electric hammer. Twist drill bits are more suitable for drilling holes in materials that are not particularly hard. Relatively speaking, their impact capabilities are weaker than those of impact drills.

2. How to drill into a cement wall with an ordinary electric hand drill

1. If you plan to use an ordinary electric hand drill to drill holes in a cement wall, it is also feasible. For example, if you need to drill holes in the wall to install an air conditioner, you can use a hand electric drill directly. However, compared with an impact drill or an electric hammer, it The power is slightly smaller.

2. If you want to achieve better drilling capabilities, you can change the hand drill bit to a harder drill bit. It is best to choose an alloy material, because if it is an ordinary drill bit, it cannot penetrate the cement wall.

3. Next, you need to make a mark on the wall where the hole will be drilled, and align it with the mark to drill the hole. You can drill a small hole at the beginning, and then drill it slowly. If there is a deviation, you need to adjust it in time.

Summary: The above content specifically introduces the difference between impact drill bits and twist drill bits. The principles used between the two, including their scope of use, are different. If you want to drill holes in a cement wall, you can use a hand drill, but you need to follow a certain method.
