Introduction and analysis of various deep hole drills
2025-05-27
There are many types of deep hole drills, each with different uses. Today, we will introduce these classifications.
The first is the gun drill. Gun drills were originally used to machine gun barrels, hence the name. It has only one cutting part, and during processing, the cutting fluid is passed through the center of the drill rod and sprayed into the cutting area through a small hole in the drill bit.
The second is the single-tube drill. The cutting fluid of this deep hole drill is delivered by pressure, so it can be used for deeper depths and has higher production efficiency.
The third is the jet-suction drill. The principle is similar to the second one, but its bore is smaller and the drilling is deeper. It also has the function of suction chips, and it is a type of deep hole drill with better current use effect.
The fourth is the DF deep hole drill. It is a combination of the advantages of BTA deep hole drills and jet drills, and it is also a testament to technological development. It has a wide range of applications and is the future trend of deep hole drill development.
The above is a brief introduction to several different types of deep hole drills. Each has its own strengths and uses. Although they are constantly developing, each of them is indispensable.
