The number, arrangement, and angle of welding on tungsten steel drill bits vary, and the shape of tungsten steel cutting tools also varies. The bottom, inner, and outer edges of tungsten steel drill bits can ensure gaps for water flow and chip removal. The upper part of the tungsten steel drill bit body is connected to the rock core tube with a screw thread. A water tank is opened on the side of the drill bit body, and a water outlet is also opened on the bottom lip surface. The sink and water outlet both ensure the circulation of flushing fluid, achieving the purpose of removing rock powder and cooling the drill bit. When drilling into clay and shale formations, in order to increase the gap, ribs are welded on the inner and outer walls of the hard alloy drill bit, which is called a rib type drill bit.

Needle shaped tungsten steel self grinding drill bits can be used in hard formations with high abrasiveness. Generally, tungsten steel drill bits can drill into strata with a drillability of II-VII, while needle shaped tungsten steel drill bits can drill into rocks with a drillability of II-VII.

Weigh the tungsten steel drill bit with an ordinary drill bit or a white steel drill bit by hand. The tungsten steel drill bit is heavier and is ground on an ordinary gray grinding wheel. The spark of the tungsten steel drill bit is dark red and difficult to grind. The spark of the ordinary drill bit or white steel drill bit is brighter.

Tungsten steel drill bits are brittle, and when they fall from their hands, one piece of the blade will fall off as soon as it falls, while other drills cannot fall off.

1. Tungsten steel is a metal material with extremely high hardness, widely used in industry in places where high hardness materials are needed, such as drill bits. However, the price is very expensive. A tungsten steel as large as an eraser costs about 100 meters, and the price is still rising.

2. Tungsten steel is a hard alloy, also known as tungsten titanium alloy. The hardness is Vickers 10K, second only to diamonds. As a result, tungsten steel products (commonly including tungsten steel watches) have the characteristic of being less prone to wear and tear.

3. Therefore, tungsten steel products (commonly known as tungsten steel watches) have the characteristic of being less prone to wear and tear. Commonly used on lathe tools, impact drill bits, glass knife heads, and ceramic tile cutting blades, it is hard and not afraid of annealing, but brittle in texture.
