Kimdrill cluster drills is capable of drilling the large diameter hole from 600mm to 3000mm (23” to 118”) in extremely hard rock formations. 

It consists of multiple DTH hammers and bits in one assembly. Each hammer designs with specially position to ensure even cutting across the hole and also to realize the most efficient and superior drilling performance. And it also fits with the quick bit change system which also enhance the drilling efficiency.
