Apply pressure as you begin to drill. Squeeze the trigger of the drill slowly at first. Gain speed as you apply more downward pressure. Allow the tip of the drill bit to penetrate the surface of the rock. Apply more pressure, increase the speed of the drill, keep the bit perfectly straight and drill into the rock until the desired depth is reached.
The position of the drill bit is changed by the rotation so that the impacts are applied to the rock in different positions. HammersWassara. This makes it the superior choice for many drilling applications where airpowered DTH hammer, top hammer or rotary drilling equipment are normally used.
