How to choose a long-life drill bit

Choosing a drill bit with a long life is mainly considered from the following aspects:

1. Consider the stratum condition

For hard rock strata, drill bits with high hardness you can select good abrasion resistance, but for soft rock strata, you can select impact-resistant drill bits

2. Reasonable preparation of drilling fluid

The performance of the drilling fluid will affect the cooling and lubricating effect of the drill bit. Unsuitable drilling fluid will accelerate the wear of the drill bit.

3. Optimize drilling parameters

The unreasonable setting of drilling pressure, rotational speed, impact frequency, and other parameters will also lead to premature wear of the drill bit.

4. Regular inspection and maintenance

Regularly check the wear of the drill bits and replace the badly worn bits in time

5. Operator's skill level

The technical level of the operator directly affects the parameter control in the drilling process, which in turn affects the life of the drill bit.

Choosing the right, high-quality drill bit can maximize the life of the drill bit

Choose the right drill bit material

-PDC Drill Bit

Those drill bits have very high wear resistance, fast drilling speed, and adaptability, and you can widely use them for drilling in soft rock, medium hard rock, and hard rock.

-DTH hammer Bit

Those bits drive the hammer up and down by compressed air to break the rock, as a result, you can use it for drilling hard rock, or broken rock.

Choose the shape of the drill bit

Spiral Angle: If the spiral angle is larger, the chips are not easily discharged, leading to overheating of the drill bit.

Rake angle: If the rake angle is too large, the cutting force will be too great, leading to excessive wear

Choose famous brand drills

The quality of drill bits of famous brands is more guaranteed, and the life is longer, such as Pearldrill， XCMG， Hengwang, and so on.
