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 bit and drill for one minute. Do not force the drill into the boulder; Let the drill do its job. Remove the drill from the hole and cool it in a pitcher. Spray the boulder lightly with water to remove dust and cool the rock.

 

3. What are rock drill bits made of?

Made of high quality alloy steel and high quality tungsten carbide. After heat treatment and shot peening, a durable and reliable balance of strength and toughness can be achieved. Large drill forgings are individually ultrasonic tested and screened for inclusions and defects. Drill bits designed 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.
