FAQ:
1. What is a button bit used for?
Button Bits for Hard Rock Drilling
Oilfield, waterwell, HDD, and geothermal drillers extensively use button bits to drill hard rock.
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. What are rock drill bits made of?
Made from premium alloy steel and high quality tungsten carbide. Heat treated and shot peened to deliver a durable and reliable balance of strength and toughness. Large bit forgings are individually ultrasonically tested and screened for inclusions and flaws. Specially designed bits for any application.
4. How do I choose a hammer drill bit?
Before selecting a hammer for rotary drilling, determine the diameter of the holes you need to drill. The diameter of the holes will dictate the type of hammer and the bit holding system you select. Every tool has its own optimal drilling range.
