What is a diamond drill bit and what types are there

What is a diamond drill bit and what types are there? The drill bit that makes the cutting edge is called a diamond drill bit. The drill bit is an integrated drill bit, the whole bit has no moving parts, the structure is relatively simple, and it has high strength, high wear resistance and impact resistance, and can be used for hard objects (such as rocks) Drill holes on it.

Types of diamond drill bits

Diamond drill bits are classified according to the way in which the abrasive is embedded in the matrix of the bit, and different methods are used to embed the diamond abrasive in the matrix to produce different types of diamond bits.

1. Impregnated diamond bit

The impregnated diamond bit matrix (hereinafter referred to as diamond bit) is formed by powder metallurgy, which is then sintered and bonded to the steel body of the bit.

2. surface diamand bit

The cutting tool part of the table setting diamond bit is also diamond single crystal, diamond polycrystalline or diamond composite.

3. Cone drill bit

A conical drill bit is a drill bit with a conical shape buried in it, and the core in the middle is crushed due to the mutual compaction of the conical shapes. This type of drill bit has a wide range of adaptability to rock hardness, especially for soft to medium hard rock, but Requires a complete stratum and is not suitable for overburden construction.

How to choose a diamond drill

The selection of the drill bit can consider the following factors: the diameter, depth and tolerance requirements of the hole. Different types of drill bits can meet different diameter ranges. Different types of drill bits have different hole-making accuracy.

We are leading manufacturer of various drill bits, diamand bit, impregnated diamand bit, surface diamand bit, etc.

Our impregnated bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to a minimum.

The optimum diamond size, concentration and matrix type are dependent on the hardness and abrasiveness of the formation to be drilled.
