What are the Characteristics of Tungsten Carbide Drill Bits?

The shape of tungsten steel cutting tool is also different depending on the number of inlays, arrangement and angle of inlays on the tungsten steel drill bit. The bottom edge, inner edge and outer edge of the tungsten steel drill bit can ensure the clearance for water passage and chip discharge. The upper part of the tungsten steel drill body is screwed to connect the core pipe, and there is a water groove on the side of the drill body and a water opening on the bottom lip. The flume and the spout ensure the flow of flushing fluid to remove rock dust and cool the bit. In order to increase the clearance when drilling clay and shale formations, ribs are welded on the inner and outer walls of the carbide bits, which are called ribbed bits.

In highly abrasive hard strata, needle like tungsten steel self-sharpening bits can be used. Generally, tungsten steel drill bits can drill into the stratum where the drillability of rock is Ⅱ to Ⅶ, while needle tungsten steel drill bits can drill into the rock of Ⅵ to Ⅷ.

The cemented carbide drill bit and ordinary drill bit or white steel drill bit are put in the hand to weigh, the tungsten steel drill bit is heavier, and put on the ordinary gray grinding wheel to grind, the spark of tungsten steel drill bit is dark red, and it is hard to grind, and the spark of ordinary drill bit or white steel drill bit is brighter.

Tungsten steel drill bit is brittle, from the hands of the ground, the edge of the avalanche on the avalanche of a piece, other drills are not avalanche.

1.Tungsten steel is extremely hard metal materials, in industry is widely used in drills and other places that require high hardness materials. However, the price is very expensive, an eraser so big tungsten steel to be about 100 meters, and now the price is still rising.

2.Tungsten steel belongs to cemented carbide, also known as tungsten titanium alloy. Hardness of Vickers 10K, second only to diamond. Because of this, tungsten steel products (common tungsten steel watches), with the characteristics of not easy to be worn.

3.Tungsten steel products (commonly found in tungsten steel watches) have the characteristic of not being easily worn. Commonly used in lathe tools, impact drill bits, glass cutter bits, tile cutter above, hard not afraid of annealing, but brittle.

Tungsten carbide drill bit (also called carbide drill bit) is a kind of drill bit made of materials composed of tungsten, carbon and other alloying elements (such as cobalt). It is widely used for drilling metal, stone and other hard materials because of its high temperature resistance, high hardness and wear resistance.

Tungsten Carbide Drill Bit Features:

High hardness: the hardness of tungsten steel drill bits is very high, generally can reach HRA 89 or above, which is much harder than ordinary steel drill bits, so it can effectively deal with the processing of hard materials.

Strong wear resistance: due to the special structure of tungsten steel, the drill bit can maintain a long service life and is not easy to be worn out under the high-intensity working environment.

Good high temperature resistance: tungsten steel material can withstand high temperature, usually not easy to fail under high temperature working environment, suitable for high speed drilling and other high temperature working conditions.

Strong pressure resistance: tungsten steel drills have strong pressure resistance and can withstand larger processing pressure, so they are suitable for high load processing occasions.

High efficiency machining: tungsten steel drill bits have high precision and good cutting performance, and generate less heat when drilling, which can effectively improve the machining efficiency.

Easy to process: Although the material of tungsten steel is hard, through advanced processing technology, it can be made into various complex shapes of drills to adapt to different needs.

These features make tungsten steel drills widely used in metal processing, stone processing, machinery manufacturing and other industries, especially suitable for precision processing and higher hardness materials.
