B116 T. C. (Tungsten Carbide) Metric Core Bit for Geotechnical Investigation Exploration Core Drilling
Product Description
Tungsten Carbide Core Bits are designed especially for soil
investigation and geotechnical drilling, but also suitable in some
applications for mineral exploration. As the tungsten Carbide is
softer than diamond stones, the formations which these bits are
able to handle are limited in the range of soft or some medium
rocks. Like the overburden drilling, cleaning of drill holes, e.g.
for the removal of steel fragments from a drill hole.
Our company is specialized in exporting many types of drilling
rigs, the products including drilling rigs for mining exploration,
water well drilling rigs, coal mine drilling rigs, borehole
drilling rigs, geological drilling machine, construction drilling
rigs, core drilling rig, etc. We also exported the truck mounted
drilling rigs, wheel mounted drilling rigs, crawler drilling rigs
and so on to meet all customers' requirements.
We are also manufactured and exported all kind of drilling
accessories, such as core bits, non-coring bits, reaming shells,
casing shoes & casing bits, core barrels, overshot, drill rods,
casing tubes and other drilling tools.
All specifications are available. If you need any further information, please feel free to contact with us.
