Roller Bits

Roller bits are special wear parts that are used in drilling through hard rock formations, for example. They comprise a base body and rotating roller equipped with carbide-covered pins that is fitted on a socket. This roller turns during the drilling process and crushes the rock, making it easier to penetrate into the hard stone.

Your advantages

• Ideal for drilling in extremely hard rock (with more than 100 MPa)
• Maximum cutting performance and smoother running thanks to ballistic carbide
• Drilling in rock without damage to equipment, smooth drilling process
• Low torque requirement, which makes it possible to use smaller equipment
• Economical alternative to MHD (cluster drill)

Our roller bits are suitable for drilling in extremely hard rock (with more than 100 MPa).
