Sandvik’s high-quality drill rods are crafted from premium alloy steel and offered in hexagonal and round configurations. These rods are engineered to provide straighter holes with minimal deviation and extended service life.
Sandvik top hammer drill bits offer extended wear life, higher penetration rates, straighter holes and longer bit life. Ranging from 28-152 mm in diameter, threaded button bits use a proprietary grade of cemented carbide throughout. Various button shapes (spherical, semi-ballistic, and conical) and skirt designs (regular or retrac) deliver optimal performance in different rock formations.
