40# steel from steel manufacturer of the leading level in
ChinaTechnologists' regular investigation on construction
sites help to set the teeth properly.Many experiments on the
sites help to design some new type drilling tools.Rich
experience of providing drilling tools for rotary drilling rigs of
Baue, Sany and other famous brands.Rotary drilling tool is one of
the most important parts in rotary drilling construction. It
directly affects the construction quality, efficiency and cost. The
two main functions of rotary drilling bit are guiding and drilling.
There is no good or bad drilling tool type. According to
different geological types, strength and construction technology,
the proper type of drilling tools should be selected to make
the most of its function and effect. Parameter:NameRotary

frequently applied High efficiency and easily unloading For
dry piling and casing construction For very hard rock, to carry out
the rock coreRotary drilling tools are mainly divided into the
following types:Double bottom double cut drilling bucket: a
standard drilling tool for rotary drilling rig. When applied for
below 500KPa total or strongly weathering rock layer, flat bucket
teeth would be used as the cutting bits for drilling buckets;
When applied for below 30MPa gravel, cobble and boulder layer and
total or strongly weathering sedimentary rock layer, bullet teeth
would be used. 2. Clam drilling bucket: high drilling
efficiency and easily unloading the slag, especially suitable for
piles of smaller diameter. It is widely applied in China for clay
layer, plastic rock layer, dense gravel and cobble layer, and
slightly hard sedimentary rock layer, etc.3. Core barrel: with
all kinds of carbide cutting bits around the bottom of the shell,
the core is broken at the joint crack, and taken out of the hole
with the core barrel. When applied for below 90MPa, bullet
teeth would be used as the cutting bits for the core barrels; When
applied for above 60Mpa, roller bits would be a better choice as
the cutting bits for the core barrels.4. Auger, previously as a
standard drilling tool for rotary drilling rig, nowadays is
gradually replaced by other drilling tool types in China, because
of the low unloading performance, and low drilling performance for
hard rock layer. However, augers are still suitable for dry piling
construction and casing drilling construction, and gravels,
boulders and total or strongly weathering rock layer.5. Belling
bucket: for improving the bearing capacity of the pile bottom.6.
Clean-out drilling bucket: for furtherly cleaning out the slag from
the pile bottom.***Casing, as a supplement for drilling tools,
is for protecting the pile wall from collapse in loose
formation, and prevent groundwater into the pile, and benefits the
decrease of pile gradient. Casing consists of single wall casing
and double wall casing. Casing elements include casing driver,
casing, casing shoe, etc.In accordance with the complicated
construction requirement, we have produced more than the above
mentioned types of drilling tools. Here is some samples as below:
For any advice about selection of rotary drilling tools, please
email usProduction of rotary drilling toolsThe production of rotary
drilling tools must be carried out in strict accordance with the
process standards. The process quality control work should be done
well. The self-inspection, mutual inspection, general inspection
system should be checked, and the quality records should be kept
timely, accurate, clear and complete to ensure product
qualityShipment and package of rotary drilling tools:Package: iron
support and wrapped with plastic filmTransportation: by sea, land
and air.Main ports: Manzhouli, Tianjin, Qiangdao, Shanghai, Yiwu,
