Diamond Core Bit

: http://geotec-drill.com/1-diamond-tools/1-diamond-bits-1.html

Drilling holes in hard rocks is easier, safer and more efficient with a diamond core bit, Ranging in diameter from 28 to 600mm, the diamond hole saw has a super hard, wear resistant synthetic diamond grit on the contact surface. It creates hole without the need to break up the core (the core is what's left inside the cup-like bit after drilling).

The diamond core bit is durable and cuts extremely fast, without chipping the material it works on. Materials that the hole saw can work with include stone, wall, masonry, marble, and granite. Water is needed during drilling to effectively cool down the diamond tool bit in order to get the maximum output. This is a wet cut core drill bit, meaning that water is needed during the drilling process.
