Diamond hole saws /diamond core drill bits Dry or wet cutting/drilling
Diamond hole saws are also called diamond core drill bits . 1. Laser welded diamond core drill bits can be used in wet and dry drilling, but not all materials to be drilled are suitable for dry drilling. Very hard materials like reinforced concrete, normally should be drilled with water, otherwise the excessive heat generated during the drilling process may cause the diamonds on the core bit to become blunt, and then lead to poor drilling performance. The situation is just like concrete diamond blades for reinforced concrete cutting. 2. Silver braed diamond core drill bits are most used in wet condition, if not, the diamond segment will be dropped off from the core because of the heat caused by drilling hard materials such as hard concrete,granite,marble,tile,etc. 3. Electroplated diamond core drill bits are mosted used in wet condition also for cutting,drilling marble,granite,tiles,glass,etc. 4. Vacuum Brazed diamond core drill bit can be used in dry condition.
