What Are the Different Types of Button Rock Drill Bits?

Button rock drill bits are an essential tool for drilling through hard rock formations in top hammer rock drilling. They are designed with carbides button on the tip that provides a high impact force and helps to break through the rock surface. Button rock drill bits are available in different types, each with its own unique features and benefits. In this article, we will explore the different types of button rock drill bits and their applications.

Standard button rock drill bits

Standard button rock drill bits are the most commonly used type of button rock drill bit. They are designed with carbide button on the tip and are suitable for drilling through hard rock formations. Standard button rock drill bits are available in a range of sizes and can be used for both surface and underground drilling.

Retrac button rock drill bits

Retrac button rock drill bits are designed with a retractable drill bit that can be extended and retracted as needed. This feature allows the drill bit to maintain a constant contact with the rock surface, resulting in a more efficient drilling process. Retrac button rock drill bits are ideal for drilling through loose rock formations and are commonly used in mining and tunneling operations.

Drop center button rock drill bits

Drop center button rock drill bits are designed with a slightly concave tip that creates a central depression on the rock surface. This feature allows the drill bit to maintain a more stable contact with the rock surface, resulting in a more efficient drilling process. Drop center button rock drill bits are suitable for drilling through hard rock formations and are commonly used in quarrying and mining operations. For efficient and safe mining and tunneling operations, selecting the right type of mining drill bits is crucial.

Ballistic button rock drill bits

Ballistic button rock drill bits are designed with multiple carbide buttons on the tip that provide a higher impact force and a faster drilling process. This type of carbide button bit is suitable for drilling through medium-hard rock formations and is commonly used in quarrying and mining operations.

Spherical button rock drill bits

Spherical button rock drill bits are designed with many spherical carbide buttons on the tip that provides a high impact force and is highly resistant to wear and tear. This type of drill bit is suitable for drilling through hard and abrasive rock formations and is commonly used in mining and tunneling operations.
