MAXDRILL ROCK TOOLS CO.LTD

1. Threaded drills
-Threaded ball tooth drill
Threaded joint column tooth brazing head is mainly with the hydraulic rock chisel machine (or wind chisel machine) and hydraulic brazing (wind-moving brazing) supporting the use of a drill bit, through different forms of thread and brazing, drill ingestoperation operation, drill head diameter from 32-203mm, mainly used in underground mining, open-air mining. Threaded ball teeth drill using high-quality steel and carbide for raw materials manufactured, after a special heat treatment process, the ball tooth drill can meet the requirements of strong hardness of rock formation, and can minimize the loss in the energy transfer process, solid tooth strength uniform not easy to lose teeth and teeth, so that the impact energy can be concentrated on the rock, to achieve the purpose of high-efficiency excavation.
2. Taper drills
- Taper ball tooth drill
Taper-connected column-tooth brazing head is mainly a drill bit used in conjunction with wind-moving rock drilland and cone rod, through taper and brate joint, for drilling operation, mainly used in the mine's secondary crushing, anchor support, laneway excavation and other fields, suitable for hard and very hard rock operations. As an upgrade product of a word and cross drill, the taper ball tooth drill because of its head carbide teeth and hot-plated trouserbody makes it good digging effect and long service life, its non-grinding life is about 5-6 times the same diameter blade head grinding life of 5-6 times, is conducive to saving auxiliary working hours, reducing the worker's physical labor and speeding up the engineering speed. Therefore, different diameter saperall connections and threaded connection ball teeth brazing heads are widely used in various types of hard and brittle rocks with drilling car drilling rock.
(1) Type: Ball teeth Size: 19mm, 22mm, 25mm
(2) Diameter: 38-42 mm.
(3) Taper: 4 degrees 46 degrees, 6 degrees, 7 degrees, 11 degrees, 12 degrees
(4) Packaging: Carton packaging
(5) Capacity: 50,000 units/month
3. Tapepon brazing
The tapered blots generally refer to the blots made of H22 and H25 hexagonal hollow brazing steel. It is suitable for small pneumatic rock drill or hydraulic rock drill. The cone-shaped brazing rod is a conical shape, and the tapered-linked brazing head can be used to drill rock, usually used in drilling operations such as rock drilling, expansion and other quarries, coal mines, roadfoundations, construction and other fields.
The taper blower is used in conjunction with the taper brazing head and is used in different lengths for different occasions. The cone angle is usually 7 degrees, the international traffic is 12 degrees, the diameter of the cone is usually 25, can also be produced according to the needs of the user , 22 or other specifications. Light rock chiopers are usually equipped with tapered brazing of 7 degrees and below, while high-power rock drills mainly use 11 degrees and 12 degrees of tapered brazing.

4. Overall brazing
The overall brazing is a brazing tool, brazing, brazing and tailings, the advantages are: eliminate the energy loss at the conical brazing connection, high efficiency; Its use range is the scope of tapered brazing, and extends to the scope of wind brazing secondary crushed rock. When the head alloy sheet is normally scrapped, it can be cut for tapered brazing. Usually the whole brazing is used for underground mining and small hole drilling, with small power rock drillers such as air-legged or handheld use. It can effectively reduce the loss of impact energy, improve the speed and efficiency of drilling. When the rock is soft and easy to chisel, the use of integral brazing can greatly improve the rate of rock drilling. The overall brazing is usually suitable for drilling holes between 24 mm and 44 mm in diameter.
The drilling speed of the overall brazing of Myerin drilling is fast, the effective utilization rate of impact energy is 18% to 25% higher than that of the active brazing head, it is easy to retreat, does not need to handle the brazing head, and avoids the problems such as brazing pants, cracking pants, brazing cones breaking. The whole tool after wear can also be polished into a tapered tool. (It is recommended to drill in the lower small diameter rock holes with a serious rate of brazing loss, or to drill a light rock drill with a diameter of less than 42mm).
Depending on the application, the length is usually 600 millimetres to 9600 mm, etc.
1 Material: 95CrMo
(2) Brazing tail size: Hex.19 , Hex.22 (quarrying brazing also applies)
(3) Head diameter: 24mm-44mm
(4) Length: 0.4m-10m
(5) Packing: wooden boxes or bundles
(6) Capacity: 20,000 pieces/month
5. Brazing tail
Brazing tail is mainly used in mining operations, the selection of high-quality alloy steel as a raw material, after the overall carburetod treatment. The use of dedicated CNC machine tool processing equipment and processing processes to ensure tail details, internal water holes and side water hole processing quality. The brazing tail is evenly heat treated and scientifically straightened using precision instruments to ensure the straightness and irritability of the brazing tail. The brazing tail is used to transfer the energy of the drilling rig and drill pipe, one end is connected to the drill rig, one end is connected to the drill pipe, so the drilling rig's energy can be transferred to the drill bit, and finally to achieve the purpose of digging. Our brazing tails are available for: Atlas Copco, Furukawa, Ingersoll-rand, TAMROCK, etc.
