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

Needle shaped tungsten steel self grinding drill bits can be used in hard formations with high grinding properties. Generally, tungsten steel drill bits can drill into formations with rock drillability levels of II-VII; Needle shaped tungsten steel drill bits can drill into rocks of grades VI to VIII.
