Rotary drill bits
The Sandvik range of rotary drilling bits includes geometries and cemented carbide grades for different surface and compressive strengths, abrasiveness, massiveness and homogeneity of rock as well as for various penetration rates and capabilities and characteristics of the drill rig. Innovative bearing technology and improved geometry, materials and machining methods provide longer bearing life.
The selection of Sandvik rotary drill bits covers both blasthole bits for mining applications and bits suitable for construction and civil engineering applications. The product covers hole diameters from 159 to 406 millimeters (6 ¼ to 16 inches). Both air-cooled and sealed bearings are available, as well as various carbide grades and insert geometries with cutting structures optimized for all conditions.
- Insert shapes and grades designed to provide long life and high productivity
- Longer service life for decreased machine downtime
- Air-cooled bearing performance optimized for high hours by advanced metallurgy, proportioning of components, and optimized geometries
