Features
 

1. Cost - Initially cheaper investment

2. Less Impact Damage - Impact is less damaging to the cutting structure

3. Better in Hard Rock Formations - The fracturing action of a button bit is better in non-homogeneous rock      formations.

4. More Control Over the Bit - In directional drilling applications, a button bit is easier to control offering            lower torque, greater flexibility and a more steady tool face.
