Because not all drill bits are created equal, it is important to understand the characteristics of the drill bit material, coating, and frequency of use to select the right drill bit for stainless steel.
The first thing to consider is the material, because stainless steel is an extremely hard material, and if you choose drill bits that drills wood to drill stainless steel, it will not achieve the desired results. Therefore, the drill bits for stainless steel needs to be harder than the steel itself. Carbide is one of the materials used in stainless steel drill bits. Titanium and tungsten carbide are almost as hard as diamond, making them ideal for penetrating steel. These carbide-infused drill bits are a reliable choice for drilling stainless steel.
The second thing to consider is the coating. Many manufacturers add metal coatings to construction materials such as drill bits. These coatings can improve penetration and protect the drill bit. Black oxide coatings can reduce friction and heat, which are important factors to consider when drilling metal.
Also consider the frequency of operation. Because high-speed metal drilling generates excessive friction and heat. The extra pressure on standard drill bits tends to wear them out quickly.
