The number, arrangement and welding angle of the tungsten steel drill bit are different, and the shape of the tungsten steel cutting tool is also different. The bottom edge, inner edge and outer edge of the tungsten steel drill bit can ensure water flow and chip removal. gap. The upper part of the tungsten steel bit body is threaded to connect the core tube, the side part of the bit body is provided with a water groove, and the bottom lip is also provided with a nozzle. Both the sink and the nozzle ensure the circulation of the flushing fluid, and achieve the functions of removing rock dust and cooling the drill bit. In order to increase the gap when drilling into clay layers and shale formations, ribs are welded on the inner and outer side walls of the hard alloy drill bit, which is called a ribbed drill bit. Needle-shaped tungsten steel self-grinding drills can be used in hard formations with high abrasiveness. Generally, tungsten steel drill bits can drill into stratum with rock drillability of grade II to VII, and needle-shaped tungsten steel drill bits can drill into rock of grade VI to Ⅷ. Tungsten steel drills are weighed with ordinary drills or white steel drills. The tungsten steel drills are heavier. Place them on an ordinary gray grinding wheel. The sparks of the tungsten steel drills are dark red and difficult to grind. Steel drills have brighter sparks. The tungsten steel drill bit is brittle. When dropped from the hand, one piece will be broken when the cutting edge breaks. Other drills cannot be broken. 1. Tungsten steel is a metal material with extremely high hardness. It is widely used in industries where high hardness materials are required, such as drill bits. However, the price is very expensive. A tungsten steel as big as an eraser costs about 100 meters. The price is still rising. 2. Tungsten steel belongs to cemented carbide, also known as tungsten titanium alloy. The hardness is Vickers 10K, second only to diamond. Because of this, tungsten steel products (commonly tungsten steel watches) have the characteristics of not being easily worn. 3. Because of this, tungsten steel products (commonly tungsten steel watches) have the characteristics of not being easily worn. It is often used on lathe tools, impact drill bits, glass cutter bits, and tile cutters. It is hard and not afraid of annealing, but it is brittle.
