Wassaras water-powered DTH hammers generate a high piston frequency. The hole straightness is controlled by a tight tolerance between the hammer and the bit diameter. This gives good flexibility in the use of different drill bit designs. Wassara is offering drill bits optimized for the water-powered drilling technology, designed to ensure a long hammer life. They have a front designed for optimal efficiency with dedicated water channels on the striking face. We strongly recommend following the recommendations in Wassara’s Product Selection Guide to get the best drilling performance.
