Features and Advantages
1.Particularly suitable for difficult ground conditions.
2.An efficient installation since drilling, placing and grouting can be performed in a single operation, saving both time and money.
3.Self-drilling system eliminates the requirement for a cased borehole in collapsing soils.
4.Fast, single-step anchoring system with simple equipment able to work with standard track drill (top hammer) or hand-held drilling equipment, eliminating the need for larger casing rigs.
5.Installation with simultaneous drilling and grouting possible, and post grouting system is simple.
6.Continuously drilling and grouting under high pressure causes the grout to permeate into looser soils and creates a bulb-effect for increased bond capacity.
7.Easy installation in all directions, also upwards, and similar installation methods for all ground conditions.
8.Suitable for working in limited space, height and in areas of difficult access.
9.Galvanizing for enhanced corrosion protection is available if necessary.
10.Multiple ranges of drill bits suitable for different ground conditions.
11.Continuously threaded bar pattern can be cut and coupled anywhere along its length to achieve all lengths.
Bits type:
EX: Hardened cross bit for loose to medium dense ground conditions
ES: Hardened button bit for unconsolidated rock with boulders
EC: Hardened arch bit for unconsolidated soil with small boulders
EY: Hardened 3 cutters bit for loose to medium dense ground
conditions
EXX: T.C cross bit for soft to medium rock formations
ESS: Button bit with T.C inserts for medium rock formations
ECC: T.C arch bit for soft to medium rock formations
EYY: T.C 3 cutters bit for soft to medium rock formations
Clay bits: Casted clay bit for Soft clay and soil

Mining Tool B.D of O.E.D Machinery Grop, has been dedicated in development and production of mining drill rods and drill bits for many years, which forms six main series products: taper drill tools, thread drill tools, rotary drill tools, blast furnace frill tools, DTH drill tools, and coal mining tools. We can produce high quality of nearly hundreds of products, like hexagonal thread drill rod, extension rod, speed rod, DTH drill rod, blast furnace drill rod and so on, also shank adapter coupling sleeves, button bit, chisel bit, cross bit, etc.
Our products can be widely used in many basic energy construction projects, such as exploring new mountains, minerals, metallurgy, rail, highway, and water and electricity infrastructure etc.
Our member has stong capability of researching developing and advanced production technology. We have passed ISO9001 International Wuality System Certificate, we can provide superior standard drill tools and also customized drill tools.
Our Sales company, HUNAN GOLDEN GLOBE I AND E OED CO.,LTD., have over 20 years experience of export. We have exported the products to many countries. Trust us that we can provide reliable service for you.
Why trust us and how to control the quality?
Let's me introduce our company.
We have three main workshops, heat treatment workshop, forging workshop and CNC workshop.
Material is very important for a good product. We have excellent heat treatment equipment to control the material quality. For each lot of products, we all have material certification. So even you have some special material requirement, we have best solution for you. Do not hesitate to ask us if you have any question of material. Here's our heat treatment equipment.
Turning machine and grinding machine are also very important. we have advanced CNC machines and skillfull workers to keep the stable quality.
During production, we have engineer to check the dimensions. Our workers are highly trained and they will inspect the products after machining.
For the final inspection, we'll check the dimensions one by one to make sure the quality is qualifed. The inspection report will be sent to you before shipping if you have ordered our products.
We have provided many solutions for different customers.
For example:
Our customer in Norway. They required a special hole of the drill bit to match their specific drill rod.
Our customer in Korea. We have changed the material of their skirt and carbide button bit to diminish the consumption of drill bit.
Our customer in Chile, We provided different length of drill rod as per their requirement.
Our customer in South Africa, new design of thread drill bit have been sent according to their application.
