Wassaras water-powered DTH hammers generates a high piston frequency. The hole straightness is controlled by a tight tolerance between the hammer and the bit diameter. This gives a good flexibility in 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.
To optimize the efficiency of the Wassara hammer, we recommend using an open bit face as this will remove the cuttings more efficient.
We also recommend using inserts that gives the highest penetration speed.
