1. High hardness: Tungsten steel Step Drills are made of high-speed steel, which has high hardness and can be used for drilling hard materials. 

2. High wear resistance: Tungsten steel step drills have high wear resistance, which makes them suitable for drilling into metals and other hard materials. 

3. High heat resistance: Tungsten steel step drills can withstand high temperatures, making them suitable for drilling into metals and other hard materials. 

4. Long service life: Tungsten steel step drills have a long service life and can be used for a long time without needing to be replaced. 

5. High accuracy: Tungsten steel step drills have high accuracy and can provide precise hole sizes.

Supal Tools focuses on making tungsten Carbide Drill Bits,to get greater efficiency, a series of step drill bits are developed, which can drill multiple diameter holes and contersinks in one single pass, the geometry and diameter of the drill bits can be designed according to the requirement of different shapes of the holes you need. Step drill bits are widely applied to various situations, and we offer different material options for cutting aluminum, titanium, composite material, carbon fibor, steels, cast iron and other metals.
