The hardness of rock maybe soft,medium ,medium hard ,hard and very hard.The hard ness of one same rock maybe also a little different,such as :
Limestone,sandstoneshale has soft limestone,medium limestone and hard limestone,medium sandstone and hard sandstone. So it is import to choose the siutable rock drilling bits for the different drilling project.
We have 15 years sevices experience to produce the drill bits and advanced drilling solutions for different drilling job.We have exported to more than 30 countries ,such as in the Australasian and South American Markets. We can offer different mining drill bits with the sizes ranging from 6 3/4" to 16".
