Sandvik top hammer drill bits are used for blast hole drilling in mining and construction applications. The Sandvik bits are designed to offer extended wear life, higher penetration rates, straighter holes and longer bit life. Ranging from 28-178 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 deliver optimal performance in different rock formations. This assessment includes TH bits with weights ranging from 0.27 kg to 26.0 kg. The average weight for TH bits is 1,4 kg. For further information, visit: https://www.mining.sandvik/en/
