A dry core drill bit is exactly what it sounds like: it’s dry. They have hollow centers that allow a core to be removed from the hole without leaving any material behind.
In most cases, a wet core drill bit is the best solution. Although utilizing a wet core drill bit is ideal in most circumstances, adding additional water on some operations is impractical. Consider drilling a hole in an office wall while also using water to clean things up. That might lead to a major mess. Worse, in cases involving electrical lines or equipment, water could ruin the core drill bit or cause a fire hazard. Dry core drilling generates a lot of dust, although it’s usually easier to clean up in these situations. Dry core drill bits, on the other hand, are the ideal solution when additional water is not required for the job application. When working with electrical wire, using a dry core drill bit is the safest option. Drilling medium to soft bricks with dry core drill bits is also the best solution.
There are situations when the usage of wet core bits is not recommended due to the environment. You can use dry core bits on a core drill rig or a regular portable core drill if this happens. A dry core bit can be used on a rotary hand drill with the help of an adaptor. However, disregarding the adaptor is not always a good idea because it will result in slow RPM. Blocks, bricks, and soft concrete are recommended materials when drilling with dry diamond core drill bit.
The dry core drill bits, when used without water, generate a greater degree of tension and pressure on the blade, which might cause the drilling speed to slow down. Core drill bits’ service life is considerably reduced as a result of this accelerated wear. The service life of these core drill bits is not as long as that of wet diamond core drill bits. However, there are a few points to consider in order to extend the life of dry diamond core drill bits.
- When drilling, don’t utilize too much pressure.
- Remove chips from deep holes on a regular basis and avoid applying side pressure.
- Consistently run the bit at the appropriate speed for the materials you’re working with.
