FAQ:

1. What is button bit?

Button bits, or roller cones, have rotating cones that contain tungsten carbide inserts. Tricone, or three cone bits, are the most common; however, manufacturers continue to make two cone and one cone bits.

2. How do you drill through boulders?

Apply moderate pressure to the drill, and drill for one minute. Don't force the bit into the boulder; let the drill do the work. Remove the bit from the hole, and cool it in the pitcher of water. Lightly spray the boulder with water to remove dust and to cool the rock.

3. How about the common packing?

A: If there is no special packing demand, we will take it as our normal packing. First in small carton, and then put in the bigger carton together to make sure goods completed.
