Description :
According to the welding method, we can make a definition for the diamond core drill bits, high frequency/brazing welded core drill bit, laser welded core drill bit and electroplated diamond core drill bit. Most of the core bits in the current market is welded by high frequency/brazing, they are used for drilling stone and concrete mainly. Laser welded core drill bits are used for drilling concrete in complicated condition like water deficiency. To drill crisp material like marble, glass and ceramic porcelain, vacuum welded core drill is a good choice.
Advantages:
Less dust means safer work environment for miners
Lower total forces means less wear and tear on machinery
Lower vertical forces mean better penetration with less damage of the bit
Lower drag forces mean less power needed to push the pick through the cut
Applications:
1. Urban subway, high-rise buildings, airport, Geothermal hole,foundation anchoring.
2. Jet grouting and dewatering.
3. The blast hole,the anti-floating anchoring hole.
4. It can be also used for pipe shed engineering.
