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 does a rock drill bit work?
A DTH drill has a drill string with a drifter attached to the end,
which is located in the bottom of the hole. Rock is crushed by
directly striking the bit attached to the drifter. A rotary drill
crushes rock by applying crushing force to the bit on the end of
the drill string, which is pressing into the bedrock.
