What istungsten steel drill bitThis problem is inevitable for those who have friends. Carbide drill bits break rock by the impact load generated by the weight and rotation of the bit. In rock drilling, the drill bit is subjected to high-frequency impact loads and various complex stresses, such as torsion, bending, tension and compression. It is suitable for rocks, rock powder and mineral water under high-speed rotation and collision environment. Media wear and corrosion.

The upper part of the drill body is provided with a threaded connection core tube, the side surface of the drill body is provided with a water tank, and the lower lip surface is provided with a nozzle. Flows and nozzles ensure the flow of flushing fluid and provide debris removal and bit cooling. In order to increase the gap when drilling clay and shale formations, the ribs of the carbide drill bit are welded to the inner and outer walls, which is called a ribbed bit. Needle-shaped carbide self-grinding drill bits can be used in hard formations with high abrasives. In general, cemented carbide tungsten steel drill bits can drill into grade II to grade rock formations. Needle-shaped carbide drill bits drill into rock from Class VI to Grade.

There are four basic types of tungsten steel drill bits: solid carbide drill bits, indexable carbide insert bits, welded carbide drill bits and replaceable carbide crown. Each drill has the advantage of being suitable for specific machining conditions. Carbide drill bit Carbide indexable insert, tungsten steel drill bit adopts carbide indexable drill bit, which can process various apertures.

　　tungsten steel drill bitIt is made by smoothly welding the carbide tooth crown to the steel body of the drill bit. The drill bit uses self-centering geometric edges to reduce cutting forces. It provides chip control for most workpiece materials. The surface finish of the processed hole is good, and the dimensional accuracy and positioning accuracy are high. Perform subsequent finishing. The drill bit uses an internal cooling system and can be used in machining centers, CNC lathes or other high-rigidity, high-speed machine tools.

The variable carbide crown tungsten steel drill bit is a new generation drilling tool. It consists of a steel drill body and a replaceable integral hard alloy crown. Compared with welded carbide drill bits, its processing accuracy is 8.5kg, but because the tooth crown can be replaced, the processing cost can be reduced. Increase drilling production. The drill can accurately increase the hole diameter, and has an automatic centering function, so as to obtain a high hole diameter processing accuracy.

The tungsten steel drill bit body and the cemented carbide crown are locked to each other through the well-ground interlocking V-groove adjacent mechanism, ensuring that the tungsten steel drill bit assembly has the same dimensional accuracy and overall rigidity as the welded cemented carbide drill bit. At the same time, the locking mechanism has only one accurate matching position, so the crown can be easily installed on the matching rod, thereby ensuring the repeated positioning accuracy when replacing the crown. When the pull rod is fastened by the locking screw, the drill body components are locked to each other smoothly and have adjacent rigidity, which is sufficient to meet the requirements of high-speed and high-speed cross-production hole processing.

When considering the cost of each well, it should also be included.tungsten steel drill bitThe total life. The overall carbide drill can only be ground 7-10 times, while the welded carbide drill can only be ground 3-4 times. However, carbide crown bits can be replaced with machined steel. At this time, the steel drill body can replace the crown at least 20~30 times.
