What is the rock button bit

A rock button bit is a type of drill bit used in drilling operations, typically for hard rock formations. Button bits are categorized based on the shape of the button face, and they are generally divided into flat head and ball tooth types. The ball tooth type is more commonly used, and it is often referred to as a cylindrical tooth bit.

The shape of the button face on the cylindrical tooth full-face drill bit determines its classification. These can be divided into:

Flat face button bits,

Convex (or concave) face button bits.

Advantages of Rock Button Bits

The convex face rock button bit has a self-grinding feature during the drilling process. This results in several benefits:

Fast drilling speed,

Long service life,

Accurate positioning,

Coarse rock cuttings,

Low dust generation,

No need for additional grinding.

These features make rock button bits an efficient and durable choice for drilling in hard rock formations.
