Diamond Core Bit

According to the welding method, we can make a definition for the diamond core drill bits, high frequency welded core drill(silver and copper welding), laser welded core drill and vacuum welded core drill. Most of the diamond core drill bits in the current market is welded by high frequency, they are used for drilling stone and concrete mainly. Laser welded core drills are used for drilling/coring 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.

Quality diamond core drill bits set with laser-welded or High-Frequency weld segments. The high diamond concentration provides exceptionally high cutting performance as well as long operating life, especially recommended for hand-operated and stationary wet drilling. Suitable for reinforced concrete, asphalt, masonry, natural and artificial stone.
