How do carbide gun drills compare to other drilling tools in process equipment?

Carbide gun drill is a kind of drilling tool commonly used in process equipment, compared with other drilling tools, it has the following advantages:

1. High hardness: Carbide gun drill consists of a carbide head and a steel rod, the carbide has high hardness and can withstand higher drilling power and larger impact force, so it can carry out high-speed and high-precision drilling processing on harder workpieces.

2. High precision: Due to the high hardness of carbide gun drill, it can ensure the cutting stability during drilling and reduce the cutting force, which makes the drilling shape more accurate, with small diameter error and good surface quality, and can meet the requirements of high-precision machining.

3. High efficiency: Carbide gun drill has high drilling speed and large drilling depth, which can quickly complete the drilling task and improve work efficiency. At the same time, due to the good thermal conductivity of cemented carbide material, and the reasonable structure design of the gun drill, the cutting heat is effectively distributed to reduce the wear of the workpiece and the drill bit, and prolong the life of the tool.

4. Multi-functional: Carbide gun drills are highly adaptable and can be used for drilling and processing of a wide range of materials, such as steel, cast iron, aluminium alloy, stainless steel and so on. At the same time, carbide gun drills can also be used to process various shapes of holes, such as straight holes, blind holes, inclined holes and other drilling forms.

5. Low cost: compared with other drilling tools, the price of carbide gun drills is relatively low, and the service life is long, the replacement frequency is low, which can save the cost for users.

6. Environmental protection: Carbide gun drilling does not produce a lot of chips in the process, does not require coolant, less pollution to the environment, in line with the requirements of sustainable development.

It should be noted that there are some shortcomings of carbide gun drilling:

1. limited cutting speed: the cutting speed of carbide gun drill is relatively low, when processing harder materials, due to the brittleness of the carbide material, the chip discharge is difficult, easy to produce cutting resistance, reducing processing efficiency.

2. Higher requirements for overcutting and cutting angle: Because the edge surface of the carbide gun drill is fragile and prone to cracks, the control requirements for overcutting and cutting angle are higher and require special attention.

In summary, as a commonly used drilling tool, carbide gun drill has the advantages of high hardness, high precision, high efficiency, multi-functionality, low cost and environmental protection in process equipment. At the same time, it is also necessary to choose the appropriate carbide gun drill according to the specific processing requirements and material characteristics, reasonable use and maintenance to ensure its excellent performance and life.
