High Quality Electroplated Diamond Core Drill Bit For Medium Hard Layer

Electroplated diamond drill bits, also known as surface mounted diamond drill bits, are a special process formula that uses electroplating technology to fix and bond diamond sand at the contact point between the drill bit body and the rock. Many people have a misconception in this: they directly welded the diamond onto the drill bit, but in reality, it was only partially wrapped with diamond sand. In the process of friction with the rock, other components in the special formula are rubbed off, exposing diamond sand. Diamond sand can quickly grind the rock and play a role in rapid drilling.

According to the different rock layers, there may be heights, lows, and conventional specifications. The three specifications can adapt to matching rock layers, allowing for quick drilling and improving work efficiency.

According to the different hardness of rock layers, the matrix hardness is divided into heights of 30 ° -40 °, conventional depths of 15 ° -25 °, and low depths of 5 ° -15 °, which are suitable for different rock layers.

We have regular size inventory year-round: 75 #, 91 #, 110 #, 130 #, 150 #, 171 #, 219 #, larger sizes that our company can customize.

Main use:

1, Used for core drilling in geology, coalfields, metallurgy, building materials, and mines;

2, Used for rock core engineering survey drilling in highways, railways, bridges, building construction, water and electricity, etc;

3, Used for grouting reinforcement drilling in weak and dangerous rocks, foundation treatment, and fractured strata;

4, Used for large-diameter engineering drilling, hydrological well drilling, building pile foundation, and inverted hole construction drilling;

5, Used for ventilation and exhaust in tunnels, monitoring drilling of rock structures, and concrete sampling drilling.
