Concave PDC Diamond Non Core Drill Bits for Hard Rock

Product Description

1.PDC drill bit is super hard material combined with diamond and hard alloy under high temperature. It has the advantages of hard and durable from diamond, and has the advantages of high impact resistance and big blade from hard alloy. It greatly improves the drilling efficiency and is the ideal drill bit for the drill operation of medium & hard as well as super hard rock.
2. The carrier of PDC bits is forged and pressed by first-class steel. Its mechanical capacity is strengthened by fully automatic vacuum heat treatment equipment.
3.The ordinary type adopts Chinese PDC as its blade, while the super-strong type adopts American blade made by GE. Choosing proper type makes high ratio of performance and price.
4.Our PDC drill bits are widely used in all industries, such as coal mining, oil exploration, geological exploration, water and hydroelectric, railway and road, tunneling construction and so on.
5.Two-wing PDC anchor bits (semi-round standard type) is applied to the hardness not bigger than f8. The working life is 10-30 times of the ordinary alloy bits, and the efficiency could be improved by 60%. Besides, the PDC bits don't requires figuring, which lows the labour intensity and helps to saves cost.
6.GE, American company, produces the main material of the blade for two-wing PDC anchor bits (semi-round strengthened type). The diamond content is 1.5 times of the ordinary bits, which has excellent abrasive resistance and applied to medium and hard rock (f≤12). Super strengthened PDC bits adopts newly designed ball type diamond as its blade. Features: fast drilling speed, high impact resistance.
7.When the drill bits work, the edge is used to cut ordinary and symmetrical formation, while the ledge acts as cushioning to avoid huge drilling footage, which helps to low the possibility of damage. Thanks to that, the drilling level of complicated formation is improved.High-efficiency Reaming Bit and button drill bit tapered drill bits

Maintenance Instructions
1. During normal operation, it is strictly forbidden to suddenly reverse and change the running direction to prevent the composite drill bit from falling off.
2. During normal operation, there should be no air leakage in the main air path of the air compressor, and there must be enough air volume and air pressure to prolong the service time of the diamond compact drill bit.
3. When using the new composite drill bit, it should be run-in at low speed for half an hour, and then gradually used normally.
4. When operating in a harsh geological environment, reduce the axial pressure and rotational speed to prevent the drill bit from breaking.
5. During normal drilling operations, if the drill bit needs to be replaced in the middle, it is necessary to strictly check whether there is any debris in the hole, and the new composite drill bit can be used only when the hole is clean.
6. In order to make the drill work normally and stably, the stabilizer should be replaced regularly.
7. When using the new composite drill bit, pay attention to the cleaning of the punched part to prevent debris from affecting normal use.
8. Before using the drill bit, carefully check whether the thread and teeth are in good condition, and gently push it with your hand to test whether there is no problem. There is no dust inside, the air outlet is unobstructed, and the thread is lubricated
, It can only be used after the drill is connected by means of lifting and rotating.
9. It is strictly forbidden to use the bent drill pipe to avoid the damage of the drill bit due to uneven force and affect the normal use time.
10. Choose different drill bits and operation methods according to different situations.
11. Carefully check all parts of the composite drill bit before going down the well to ensure that there is no problem with the drill bit before using it.
12. The composite drill bit should be stored reasonably to prevent dust and other debris from entering the drill bit, which will affect the normal use and the life of the drill bit.
13. The drill should be packed in a special box to avoid vibration and collision.
14. When using, take out the drill bit from the packing box and install it in the spring chuck of the spindle or in the tool library for automatic drill bit replacement. Put it back in the box after use.

Structure
A polycrystalline diamond cutter alloy drill bit is simply a PDC bit, which consists of a bit body and cutters.
(1) Drill bit body. There are two types of drill bit body: cemented carbide body and steel body.
The cemented carbide matrix is precision cast in the alloy mold, the cylindrical cutting teeth are welded on the drill bit body, and the diamond is welded at the gauge position.
The steel body drill is made of nickel, chromium and molybdenum alloy steel. After the heat treatment process, the drill body is drilled, the pillar-type cutting teeth are inserted in the hole, and the button-shaped hard alloy is inserted at the gauge position.
(2) Cutting teeth. Depending on the stratum to be drilled and the appearance design of the alloy bit, the shape, number and sorting method of the cutting teeth on the alloy bit are also different.
The cutting edge is made of thin-layer artificial polycrystalline diamond bonded to the tungsten carbide substrate by ultra-high pressure and high temperature. It has very good wear resistance, and the tungsten alloy base further enhances the impact resistance of the composite sheet.

Features of PDC Bits
(1) No moving parts;
(2) With high-efficiency cutting function;
(3) The alloy drill has a long service life;
(4) Compared with other structural types of alloy drill bits, it has a higher ROP;
(5) The impact resistance is weak;
(6) Most suitable for underground driving force drilling.
