The number, arrangement, and welding angle of tungsten carbide inserts on drill bits vary, resulting in different shapes of tungsten carbide cutting tools. The bottom, inner, and outer cutting edges of tungsten carbide drill bits ensure gaps for water flow and chip removal. The upper part of the tungsten carbide drill body is connected to the core tube with a threaded connection, and the side of the drill body features water channels. The bottom lip also has water outlets. Both the water channels and outlets ensure the flow of flushing liquid, facilitating the removal of rock dust and cooling the drill bit. When drilling through clay and shale formations, to increase the gap, ribs are welded to the inner and outer walls of the hard alloy drill bit, known as ribbed drill bits.

In high abrasiveness hard formations, needle-shaped tungsten carbide self-grinding drill bits can be used. Generally, tungsten carbide drill bits can drill through formations with rock permeability ranging from II to VII levels, while needle-shaped tungsten carbide drill bits can penetrate rock permeability levels from VI to VIII.

Tungsten carbide drill bits are heavier than regular or high-speed steel drill bits when held in the hand. When subjected to grinding on a standard gray abrasive wheel, tungsten carbide drill bits produce a dark red spark and are difficult to grind, whereas regular drill bits or high-speed steel drill bits emit a brighter spark.

Tungsten carbide drill bits are brittle; if they fall from your hand, the cutting edge can shatter and lose a piece, while other drills won't chip off.

Tungsten carbide is a highly durable metal material widely used in industries for tools requiring high hardness, such as drill bits. However, it is quite expensive; a tungsten carbide piece as small as a rubber eraser can cost around 100 meters, and prices are still rising.

2. Tungsten carbide, also known as tungsten-titanium alloy, is a type of hard metal with a Vickers hardness of 10K, second only to diamonds. This is why products made of tungsten carbide, such as tungsten steel watches, possess the property of being highly wear-resistant.

3. Consequently, tungsten carbide products (commonly found in tungsten steel watches) feature a high resistance to wear. They are frequently used on lathe tools, hammer drill bits, glass cutting blades, and tile cutters. They are hard and do not easily soften, but they are brittle.
